    Why SMS still matters for Shopify stores<\/h2>\n

    WhatsApp is popular, but SMS is still the one channel that reaches every Indian mobile number. For order updates that customers must not miss, most stores keep SMS in the mix, either on its own or as a second channel next to WhatsApp.<\/p>\n

    \"Shopify
    The main SMS types in India. Shopify order updates usually sit under service messages, while offers are promotional.<\/figcaption><\/figure>\n

    Do Shopify stores in India still need SMS if they use WhatsApp?<\/h3>\n

    Yes, most Indian Shopify stores still benefit from SMS, because it reaches any mobile number with network coverage, including basic phones and numbers with no WhatsApp account. WhatsApp is great for rich updates and invoices, but SMS is the safety net for customers you would otherwise miss.<\/p>\n

    What are Shopify SMS alerts?<\/h3>\n

    Shopify SMS alerts are automatic text messages sent to your customer when something happens to their order, such as order placed, shipped, out for delivery or delivered. In India they go through DLT, so each message uses an approved header and template. The free Fast2SMS app sends them from your Shopify store for up to 12 events.<\/p>\n

    Does Shopify send order SMS on its own in India?<\/h3>\n

    Shopify’s built-in notifications are mainly email, and for Indian SMS you need a DLT-registered sender and approved templates, which an app and SMS provider handle. That is why Indian stores use an app such as Fast2SMS: it connects your Shopify order events to your own DLT templates and sends the SMS from your approved header.<\/p>\n

    Which customers benefit most from order SMS?<\/h3>\n

    COD buyers, customers on basic phones, customers in areas with weak data, and older buyers who do not use WhatsApp much all benefit most. SMS lands in the phone’s normal message inbox without needing mobile data. For a COD parcel, an SMS that says “out for delivery today” is often what makes sure someone is home.<\/p>\n

    Is SMS more reliable than WhatsApp for order updates?<\/h3>\n

    Neither channel can promise guaranteed delivery, but they fail in different ways, which is why pairing them works. SMS needs only mobile network, while WhatsApp needs data and a WhatsApp account on that number. Sending key updates on both channels covers far more situations than either one alone.<\/p>\n

    Do customers trust SMS from a store?<\/h3>\n

    Customers tend to trust SMS that comes from a clear brand header, such as a six-letter sender ID that matches your store name. DLT makes that header verified: only your registered business can send from it. A message from your own header, with the order ID in it, looks far more genuine than one from a random number.<\/p>\n

    Which Shopify events work best on SMS?<\/h3>\n

    Short, time-sensitive events work best on SMS: COD order placed, Shipment created with a tracking link, Out for delivery, Order cancelled and Refund created. These are messages the customer needs to see even without data. Longer or richer updates, like invoices, are better on WhatsApp.<\/p>\n

    Can SMS carry a tracking link?<\/h3>\n

    Yes, SMS can carry a tracking link, as long as your DLT template has a URL variable in the right place and the link’s domain is allowed for your account. Many stores put the tracking URL in the Shipment created SMS. Operators check links in SMS, so register the domains you use when you set up DLT.<\/p>\n

    Is SMS still worth it if my customers are young and urban?<\/h3>\n

    Often yes, as a backup channel for the few events that really matter. Even urban customers switch numbers, run out of data or mute WhatsApp business chats. You do not need SMS on every event: keeping it on COD, shipment and out-for-delivery messages is a light-touch way to make sure those updates land.<\/p>\n

    What does a Shopify store need to start sending SMS?<\/h3>\n

    You need DLT registration for your business, an approved six-letter header, approved templates for each message, a PE-TM chain that includes your SMS provider, and an SMS app connected to Shopify. With Fast2SMS, the Shopify app is free, DLT support is free, and you pay only per SMS from your own wallet.<\/p>\n

    DLT basics for Shopify store owners<\/h2>\n

    DLT stands for Distributed Ledger Technology. It is the system Indian telecom operators use to register every business that sends SMS, along with its headers and templates. You do not need to understand the technology, just the steps. For the full guide, read our DLT registration A to Z FAQ<\/a>.<\/p>\n

    DLT for a Shopify store, in six steps:<\/strong><\/p>\n

      \n
    1. Pick one operator DLT portal and register your business as a Principal Entity.<\/li>\n
    2. Register a six-letter header that matches your brand, for order updates and OTPs.<\/li>\n
    3. Write one Service Implicit template per Shopify order event you want on SMS, with typed variable tags for name, order ID, amount and links, plus a Transactional template for OTPs if you use OTP login.<\/li>\n
    4. Add Fast2SMS’s TMD ID to your PE-TM chain on the portal.<\/li>\n
    5. Make your approved templates available in your Fast2SMS account.<\/li>\n
    6. Install the free Shopify app, fetch the templates, map the variables and send a test.<\/li>\n<\/ol>\n

      What is DLT registration for a Shopify store?<\/h3>\n

      DLT registration is the one-time process where your business registers on an operator’s DLT portal as a Principal Entity, then gets its SMS headers and message templates approved. Without it, operators block your business SMS. For a Shopify store, the entity is your business, and the templates are your order messages.<\/p>\n

      Is DLT compulsory for Shopify order SMS?<\/h3>\n

      Yes, DLT is compulsory for all commercial SMS sent to Indian numbers, including Shopify order updates and OTPs. Messages that do not match a registered header and approved template are blocked by operators. There is no shortcut around it, but you only do most of the work once.<\/p>\n

      What documents do I need for DLT registration?<\/h3>\n

      You usually need business identity documents such as your business PAN, GST certificate or incorporation proof, plus authorised signatory details and a letter of authorisation. Exact lists differ slightly between operator portals. Fast2SMS gives free DLT support, so the team can check your documents before you submit.<\/p>\n

      What is a Principal Entity on DLT?<\/h3>\n

      The Principal Entity, or PE, is your business, the one sending the messages. When you register on DLT, you get a PE ID or entity ID. Your headers and templates are all linked to this entity, and your SMS provider uses it when sending your messages.<\/p>\n

      Do I register on every operator’s DLT portal?<\/h3>\n

      No, you register on one operator’s DLT portal, and the registration is shared across operators through the DLT system. You choose one portal, register your entity, headers and templates there, and messages can then reach customers on any Indian network. Our team can suggest which portal to use.<\/p>\n

      How long does DLT registration take?<\/h3>\n

      Timing varies by operator portal and by how complete your documents are. Entity approval comes first, then headers, then templates, and each step has its own review. Submitting clean documents and well-written templates the first time is the best way to avoid back-and-forth.<\/p>\n

      Is there a DLT registration fee?<\/h3>\n

      Some operator portals charge a one-time registration fee for the entity, and the amount depends on the portal you choose. Fast2SMS itself does not charge for DLT help: the DLT support is free. Check the current fee on the portal before you register, since it is paid to the operator, not to Fast2SMS.<\/p>\n

      What is a header or sender ID?<\/h3>\n

      A header, also called a sender ID, is the name customers see as the sender of your SMS. For Transactional and Service Implicit messages it is six letters, often a short form of your brand, like MYSTOR. For promotional messages it is a six-digit number. You register headers on DLT under your entity.<\/p>\n

      What is a DLT template?<\/h3>\n

      A DLT template is the approved text of a message, with fixed words and blank variable slots for details like name, order ID and amount. Every SMS you send must match an approved template exactly, apart from the variable parts. Each template gets a template ID and is linked to one or more of your headers.<\/p>\n

      What happens if I send SMS without DLT?<\/h3>\n

      The operators block it. Messages that do not match a registered entity, header, template and chain are rejected before reaching the customer. In the Shopify app, you would see these as failed messages in the Logs tab with a reason, which is why it pays to get DLT right before you switch events on.<\/p>\n

      Can Fast2SMS do DLT registration for me?<\/h3>\n

      The registration has to be in your business’s name, because you are the Principal Entity, but Fast2SMS gives free DLT support at every step. The team helps you pick the portal, prepare documents, choose headers, write templates that pass and set up your PE-TM chain. Book a free meeting at fast2sms.com\/meet to start.<\/p>\n

      I already have DLT from another SMS provider. Can I use it?<\/h3>\n

      Yes, your DLT entity, headers and templates belong to your business, not to the provider. To send through Fast2SMS, add Fast2SMS’s telemarketer details to your PE-TM chain on your DLT portal and make your templates available in your Fast2SMS account. Then the Shopify app can fetch and use them.<\/p>\n

      Headers and categories for each Shopify event<\/h2>\n

      Every DLT template is registered under a category, and the category decides who you can message and when. Under the current rules there are three: Transactional, Service Implicit and Promotional. For a Shopify store, order events fall under Service Implicit, OTPs can go as Transactional, and marketing-style messages are Promotional. Use the table below as a starting point, and confirm the final choice with your DLT portal or our free DLT support.<\/p>\n

      What DLT categories exist for SMS?<\/h3>\n

      DLT templates now fall into three categories: Transactional, Service Implicit and Promotional. Transactional covers OTPs for any business, not just banks. Service Implicit covers messages that follow from a customer’s own action, like an order. Promotional is for marketing, and goes only to non-DND numbers between 10 AM and 9 PM. The old consent-based service category has been merged into Promotional.<\/p>\n

      Which DLT category should Shopify order SMS use?<\/h3>\n

      Shopify order updates normally use Service Implicit, because the customer’s own order is the reason for the message. That covers order placed, payment, fulfilment, shipping, delivery, cancellation, refund and COD messages. Service Implicit messages can reach customers at any time and are not blocked by DND, since they are not marketing.<\/p>\n

      Can a Shopify store use the Transactional category?<\/h3>\n

      Yes, for OTPs. Under the current rules, Transactional is no longer limited to banks: it covers OTP messages for any business, including a Shopify store sending login codes. Your order updates, such as order placed, shipped and delivered, still go under Service Implicit. If a template is filed under the wrong category, it may be rejected, so check with DLT support before submitting.<\/p>\n

      Which category is right for abandoned checkout SMS?<\/h3>\n

      Abandoned checkout SMS is Promotional, because no order exists yet and the message nudges the shopper to buy. That means a six-digit numeric header, sending hours of 10 AM to 9 PM only, and no DND numbers. The old consent-based service route has been merged into Promotional, as our guide to the category merge<\/a> explains, which is why most stores send cart reminders on WhatsApp instead.<\/p>\n

      Which category should a welcome SMS use?<\/h3>\n

      A welcome SMS is Promotional, since it is not tied to an order the customer placed. It needs your six-digit header and can only go out between 10 AM and 9 PM to non-DND numbers, which does not suit a message that fires the moment someone signs up. That is why most stores send the welcome message on WhatsApp. In the Shopify app, welcome also skips your opt-out list.<\/p>\n

      Which category should OTP login SMS use?<\/h3>\n

      OTP login SMS for a Shopify store can be registered as Transactional, since the Transactional category now covers OTPs for any business, not just banks. The OTP login feature needs a Fast2SMS Smart OTP setup and works only on stores with classic customer accounts, because Shopify removed legacy accounts for new stores. Order SMS work on every store.<\/p>\n

      How many headers does a Shopify store need?<\/h3>\n

      One six-letter header is usually enough for your order updates and OTPs: order placed, shipping, COD and login codes. If you also send promotional SMS, including abandoned checkout or welcome messages, you need a separate six-digit numeric header for those. Some brands register a second six-letter header for a sub-brand, but most stores keep it to one.<\/p>\n

      How do I choose a good six-letter header?<\/h3>\n

      Pick six letters that clearly match your brand, so customers recognise you at a glance: a short form like MYSTOR for “My Store”. Avoid generic words that could belong to anyone, since DLT reviewers may reject them. The header must relate to your registered business name or brand.<\/p>\n

      Can I use the same header for SMS from Shopify and from the portal?<\/h3>\n

      Yes, a header belongs to your DLT entity, so you can use it for Shopify order SMS through the app and for other service messages sent from the fast2sms.com portal. Just make sure each message uses a template linked to that header on DLT. Promotional campaigns still need their own numeric header.<\/p>\n

      Can service SMS reach DND customers?<\/h3>\n

      Yes, Service Implicit order updates and Transactional OTPs can reach customers who are on DND, because they are not marketing. Promotional SMS, which now includes abandoned checkout and welcome messages, cannot reach DND numbers. That is one more reason to keep order updates free of offers and send marketing-style messages on WhatsApp to opted-in customers.<\/p>\n

      Can I add an offer to an order confirmation SMS?<\/h3>\n

      We advise against it. Adding a discount or promotion to an order update can change how DLT treats the template, and it may be rejected as a service message. Keep order SMS purely about the order. If you want to share an offer, send it separately as a promotional SMS within the allowed hours.<\/p>\n

      Writing DLT templates for Shopify variables<\/h2>\n

      A DLT template is fixed text with blank slots. The fixed text is checked word for word, and each slot is filled with order data when the SMS goes out. The trick for Shopify is to write templates whose slots match the variables the app can map: customer name, order ID, amount, tracking number, tracking URL, order status URL and so on.<\/p>\n

      Here are sample templates we often start from. Each slot uses a typed DLT tag: green chips are {#alphanumeric#} (names, order IDs, tracking numbers), blue chips are {#numeric#} (amounts) and amber chips are {#url#} (links). Replace MyStore with your own brand, and see more examples in our Shopify DLT SMS templates<\/a> guide.<\/p>\n

      \n

      \"DLT
      A quick reference for DLT variable tags. Match each tag to the kind of Shopify data it will carry.<\/figcaption><\/figure>\n

      How do I write a DLT template for Shopify order SMS?<\/h3>\n

      Write the fixed message in plain words, and put a variable tag wherever order data will change, such as name, order ID or amount. Keep your brand name in the fixed text, keep it to one purpose per template, and submit it under Service Implicit. The Shopify app will later fill each tag with the variable you map.<\/p>\n

      Which variable tags should a Shopify DLT template use?<\/h3>\n

      Use typed tags that match the data in each slot: {#alphanumeric#} for customer name, order ID, order date and tracking number, {#numeric#} for amounts and quantities, and {#url#} for order status and tracking links. The old plain {#var#} tag is outdated. Other typed tags are {#urlott#}, {#cbn#} for a callback number and {#email#}; our DLT variable tagging guide<\/a> explains each one.<\/p>\n

      How many characters can a DLT variable hold?<\/h3>\n

      An {#alphanumeric#} tag holds up to 40 characters and must not start with www or http, a {#numeric#} tag holds numbers only, up to 40 digits, and a {#url#} tag holds a link of up to 120 characters. That is plenty for names, order IDs, amounts and tracking links, but long product names can still run over, so leave them out or map items count instead.<\/p>\n

      Should I put product names in Shopify SMS?<\/h3>\n

      Usually not. Product names can be long, can include symbols, and can push the SMS past its variable limit or into extra SMS parts. Order ID and amount are enough for the customer to recognise the order. Save product names for WhatsApp, where longer messages are normal and cost does not rise with length.<\/p>\n

      How should I handle links in Shopify SMS templates?<\/h3>\n

      Put a {#url#} tag where the link goes, write the rest of the message around it, and make sure the domains you send are whitelisted for your account. Links can be up to 120 characters and are validated before delivery. For Shopify this means your store domain for order status links and your courier or tracking domain for tracking links. Operators check links in SMS, so plan these domains before you submit.<\/p>\n

      Why was my Shopify DLT template rejected?<\/h3>\n

      Common reasons are a wrong category, a brand name that does not match your entity, variables placed where fixed text is expected, promotional words in a service template, or a link not set up correctly. Read the rejection reason on your DLT portal, fix that one thing and resubmit. Fast2SMS DLT support can review the wording for free.<\/p>\n

      Can one template cover several Shopify events?<\/h3>\n

      It can, if the wording fits, but we suggest one template per event. A customer understands “shipped” and “out for delivery” better as separate messages, and separate templates make your Logs clearer. It also avoids generic wording that DLT reviewers sometimes push back on.<\/p>\n

      Should I write the amount with Rs or the rupee symbol?<\/h3>\n

      Many stores write “Rs.” in the fixed text before the amount variable, because it keeps the SMS in plain English characters. Using the rupee symbol can switch the message to Unicode, which fits fewer characters per SMS part. Whatever you choose, keep it in the fixed text so every SMS looks the same.<\/p>\n

      How long should an order SMS be?<\/h3>\n

      Aim to fit in one SMS part: 160 characters in plain English, or 70 characters for Unicode such as Hindi. Remember that variable values add length, so allow room for a long name or order ID. Longer messages are split into parts, and each part usually counts as one SMS, so shorter is cheaper.<\/p>\n

      Can I write Shopify SMS templates in Hindi?<\/h3>\n

      Yes, DLT allows templates in Hindi and other Indian languages as Unicode. Keep in mind that Unicode SMS hold fewer characters per part, so a Hindi order update can use more SMS parts than the same message in English. Many stores keep SMS in English and use WhatsApp for local-language messages.<\/p>\n

      Where can I find more sample SMS templates?<\/h3>\n

      Our sample SMS templates for DLT<\/a> page has ready wording across many message types, and the Shopify DLT templates guide has one for each Shopify event. Adapt the wording to your brand before submitting, since copied templates with another brand’s name will be rejected.<\/p>\n

      Do I need to include an opt-out line in order SMS?<\/h3>\n

      Service Implicit order updates normally do not need an opt-out line, because they are about the customer’s own order. Promotional templates are different, and your DLT portal may expect opt-out wording there. When in doubt, ask Fast2SMS DLT support before submitting, which is free.<\/p>\n

      Connecting DLT templates in the app<\/h2>\n

      Once templates are approved on DLT and available in your Fast2SMS account, connecting them in Shopify takes a few clicks. You never copy template IDs by hand: the app fetches them for you.<\/p>\n

      The one thing to watch is the order of your variables. If your approved template reads “Hi {#alphanumeric#}, your order {#alphanumeric#} of Rs.{#numeric#}”, the first slot must be customer name, the second order ID and the third amount. The live preview shows the filled-in SMS, so a wrong order is easy to spot before a customer sees it. Fix it there, send a test, and only then turn the event on.<\/p>\n

      \"Shopify
      The Automations tab: choose SMS, WhatsApp or Both for each event, then pick an approved template.<\/figcaption><\/figure>\n

      How do I connect my DLT templates to Shopify?<\/h3>\n

      Install the free Fast2SMS app, paste your Fast2SMS API key in the Setup tab and click Validate & Save. Then open an event in the Automations tab, set the channel to SMS, and fetch templates. The app pulls your approved DLT templates from your Fast2SMS account, and you pick one for that event.<\/p>\n

      Do I have to copy DLT template IDs into Shopify?<\/h3>\n

      No, the app fetches approved DLT templates straight from your Fast2SMS account in one click. You never type template IDs, which removes the most common cause of failed SMS we used to see. You simply search the picker by template name, ID or a few words of text and select it.<\/p>\n

      Why doesn’t my new DLT template show in the app?<\/h3>\n

      The app only lists templates that are approved and available in your Fast2SMS account. If a template is still pending on DLT, or has not been added to your Fast2SMS account yet, it will not appear. Check its status in your Fast2SMS panel, then fetch templates again in the app.<\/p>\n

      How do I map Shopify data to DLT variables?<\/h3>\n

      Each variable tag in your template, such as {#alphanumeric#}, {#numeric#} or {#url#}, shows up as a dropdown. You choose which Shopify value fills it: customer name, order ID, amount, city, pincode, payment method, tracking number, tracking URL, order status URL and more, from 18+ variables. Map them in the same order they appear in the template text.<\/p>\n

      Which Shopify variables can go into SMS?<\/h3>\n

      The app offers customer name, order ID, amount, phone, city, pincode, payment method, items count, product name, order date, subtotal, discount, tax, currency, coupon code, shipping method, order status URL, tracking number, tracking URL, checkout recovery URL and invoice URL. For SMS, keep to short values and approved link types.<\/p>\n

      How do I check the SMS before customers get it?<\/h3>\n

      Look at the live preview, which shows your SMS in an iPhone-style message view with real-looking values filled in. Then use test send to deliver it to your own admin number. The app shows a request ID for the test, and the message appears in the Logs tab with its delivery status.<\/p>\n

      Which sender ID will my Shopify SMS come from?<\/h3>\n

      Your SMS goes out from the header your DLT template is approved under, as set up in your Fast2SMS account. That is why the header and template must be linked correctly on DLT. If you have more than one header, make sure the template you pick is linked to the one you want customers to see.<\/p>\n

      Can I use SMS and WhatsApp on the same event?<\/h3>\n

      Yes, set the event’s channel to Both and pick one approved template for each: a DLT template for SMS and a Meta-approved template for WhatsApp. The customer then gets both messages. Stores often do this for COD order placed, Shipment created and Out for delivery.<\/p>\n

      Can I get a copy of each order SMS on my own phone?<\/h3>\n

      Yes, turn on “Also alert admin” for the event, and a copy goes to your admin numbers. You add those in the Settings tab: one primary number plus up to 10 more. Owners often use this for order placed and cancellation alerts, so the team knows the moment something happens.<\/p>\n

      What happens if I change a template on DLT later?<\/h3>\n

      An edited or new template gets its own approval, so fetch templates again in the app and select the new one for the event. Then check the variable mapping and live preview, because the slots may have moved. Send a test to your own number before customers see it.<\/p>\n

      Is the Fast2SMS Shopify app free for SMS?<\/h3>\n

      Yes, the app is free: no subscription, no setup fee and no commission on messages. Each SMS is billed at your own DLT SMS rate from your Fast2SMS wallet, never through Shopify billing. Our free SMS and WhatsApp app for Shopify FAQ<\/a> covers every app feature in detail.<\/p>\n

      SMS vs WhatsApp for each event<\/h2>\n

      You can choose SMS, WhatsApp or Both for every event. There is no single right answer, but after many Indian store setups, these are the choices we suggest most often. For wording ideas per event, see Shopify order events on SMS and WhatsApp<\/a>.<\/p>\n

      Should I send Shopify order updates on SMS or WhatsApp?<\/h3>\n

      Use WhatsApp for rich updates and SMS for the must-see ones, or send both on key events. WhatsApp shows your verified business name, buttons and invoice PDFs. SMS reaches any number with network. Most Indian stores end up with a mix, and the app lets you set the channel event by event.<\/p>\n

      Is WhatsApp cheaper than SMS for Shopify?<\/h3>\n

      It depends on your DLT SMS rate. A WhatsApp utility message such as an order update costs ₹0.25 per delivered message at Fast2SMS rates, and failed WhatsApp messages are refunded within 48 hours. SMS is billed at your own DLT SMS rate per SMS part. Compare the two using your own SMS rate from the Fast2SMS panel.<\/p>\n

      When does sending both SMS and WhatsApp make sense?<\/h3>\n

      Send both on events where missing the message causes a real problem: COD order placed, Shipment created, Out for delivery, Order cancelled and Refund created. For friendlier events like Delivered or Welcome, WhatsApp alone is usually enough. Both channels means two charges, so use it where it pays off.<\/p>\n

      Does the app fall back to SMS if WhatsApp fails?<\/h3>\n

      The Shopify app sends on the channels you choose for each event, so to cover both, set the event to Both. If a message fails, the Logs tab shows the reason and lets you retry. For OTP login specifically, the channel follows your Smart OTP configuration in Fast2SMS.<\/p>\n

      Do I need DLT for WhatsApp messages?<\/h3>\n

      No, DLT applies to SMS only. WhatsApp templates are approved by Meta instead, through your WhatsApp Business API account in the Fast2SMS panel. So if your DLT approval is still pending, you can start with WhatsApp for order updates and add SMS once your templates are approved.<\/p>\n

      Which channel is better for COD customers?<\/h3>\n

      For COD, we usually suggest Both. COD buyers include many first-time and basic-phone customers, and SMS makes sure the message lands. WhatsApp lets them reply easily if they did not place the order or want to change something. Replies are read in Live Chat in your fast2sms.com portal.<\/p>\n

      Which channel is better for tracking updates?<\/h3>\n

      Both work well. SMS gives the tracking number even when the customer has no data, and a tracking link if your template allows it. WhatsApp can put the tracking link behind a Track Order button. Shipment created on Both and Out for delivery on SMS is a common setup.<\/p>\n

      Which channel should I use for abandoned checkout?<\/h3>\n

      Most stores use WhatsApp for abandoned checkout, because the recovery button is easier to tap and SMS for this event needs a Promotional DLT template with a six-digit header. Promotional SMS can only go out from 10 AM to 9 PM and not to DND numbers, which clashes with a timed reminder that may fire late at night. WhatsApp avoids those limits.<\/p>\n

      Can I switch an event from SMS to WhatsApp later?<\/h3>\n

      Yes, change the channel on the event any time, pick an approved template for the new channel, map the variables and check the preview. Your old template choice is kept if you switch back. Send a test after any change to be safe.<\/p>\n

      Do customers mind getting both SMS and WhatsApp?<\/h3>\n

      For important moments like COD confirmation or out for delivery, most customers are glad to be told. For routine updates, two messages can feel like a lot, so keep Both to a few key events. Watch replies and opt-out requests in your portal to see how your own customers feel.<\/p>\n

      Delivery, logs and failed SMS<\/h2>\n

      Once your events are live, the Logs tab in the Shopify app becomes your daily check. It lists every message with its status, shows a reason for anything that failed, and lets you retry. For deeper checks, your Fast2SMS panel keeps full delivery reports.<\/p>\n

      \"Shopify
      The Logs tab: event, channel, masked phone, time and status for every message, with one-click retry.<\/figcaption><\/figure>\n

      How fast are Shopify order SMS sent?<\/h3>\n

      The app sends order SMS within seconds of Shopify reporting the order event, and it sends in parallel so a sale rush does not build a long queue. Final delivery then depends on the operator network and the customer’s phone being on and in coverage. No provider can honestly promise guaranteed delivery, but you can see every status in the Logs tab.<\/p>\n

      How do I check if a customer received the order SMS?<\/h3>\n

      Open the Logs tab in the Shopify app and find the message by event and time. Each row shows the event, channel, the customer’s masked phone number, the time and the delivery status. If you need more detail, search the same message in the delivery reports in your Fast2SMS panel.<\/p>\n

      Why did my Shopify SMS fail?<\/h3>\n

      The most common reasons are a DLT problem, such as text that does not match the approved template, a header not linked to the template or a PE-TM chain mismatch. Other reasons include an invalid or inactive number, a link that is not allowed, or low wallet balance. Hover over the failed message in the Logs tab to see its reason.<\/p>\n

      What does “template mismatch” mean?<\/h3>\n

      Template mismatch means the SMS text did not match any approved DLT template for that header. It usually happens when a variable value is too long, contains characters the template does not allow, or when the wrong template is linked to the event. Check the variable mapping and the live preview, then retry. Our guide on SMS not delivered and DLT errors<\/a> lists more error types.<\/p>\n

      Can I retry failed order SMS?<\/h3>\n

      Yes, click retry on any failed message, or use “Retry all failed (7 days)” to resend every failed message from the past 7 days at once. Fix the cause first, for example the template mapping, the DLT chain or your wallet balance, otherwise the retry will fail for the same reason.<\/p>\n

      Why are some SMS delivered late?<\/h3>\n

      A late delivery usually happens after the SMS has left Fast2SMS: the customer’s phone was switched off, out of coverage or had a full inbox, and the network delivered it when the phone came back. The app itself sends within seconds. The delivery time shown in your Fast2SMS reports helps you see where the delay happened.<\/p>\n

      Do SMS to DND numbers fail?<\/h3>\n

      Service Implicit order updates are not blocked by DND, so order SMS reach DND customers normally. Promotional SMS are blocked for DND numbers by design. If order SMS to DND numbers are failing, the template may be registered under a promotional category by mistake, so check it on your DLT portal.<\/p>\n

      Why did SMS with a tracking link fail?<\/h3>\n

      Operators check links inside SMS, and a message can be blocked if the link’s domain is not allowed for your account or the link sits in a slot not set up for URLs. Make sure your template uses a URL variable where the link goes, and that your store and tracking domains are registered. Fast2SMS DLT support can check this with you.<\/p>\n

      Can I export SMS logs from Shopify?<\/h3>\n

      Yes, the Logs tab has a CSV export you can open in Excel or Google Sheets. It is useful for matching SMS against orders, reviewing failures with your team, or keeping a record. For every message on your account, including those sent outside Shopify, use the reports in your Fast2SMS panel.<\/p>\n

      Why is the phone number masked in the logs?<\/h3>\n

      Phone numbers are masked in the app to protect customer privacy, so anyone who opens the Logs tab cannot copy full numbers. Customer phone numbers are also encrypted at rest with AES-256-GCM. You can still match a message to an order using the event, time and order details.<\/p>\n

      What should I check first if no SMS are going out?<\/h3>\n

      Check four things in order: the Setup tab shows Connected, the event toggle is on, the event’s channel includes SMS with a template selected, and your Fast2SMS wallet has credit. Then look at the Logs tab for failure reasons. If you are still stuck, email support@fast2sms.com or call +91-6262778822.<\/p>\n

      Why did the customer get the WhatsApp message but not the SMS?<\/h3>\n

      SMS and WhatsApp travel on separate systems, so one can succeed while the other fails. An SMS can fail on a DLT issue, such as a template mismatch or chain problem, while the WhatsApp message goes through Meta without DLT. Check the SMS row in the Logs tab for its reason, fix it and retry.<\/p>\n

      Does a failed SMS cost money?<\/h3>\n

      SMS billing depends on your Fast2SMS account and route, so check your SMS terms in your Fast2SMS panel or with sales on +91-6262778811. For WhatsApp, the rule is clear: messages are billed on delivery, and failed WhatsApp messages are refunded within 48 hours.<\/p>\n

      PE-TM chain and compliance<\/h2>\n

      The PE-TM chain is the path your SMS takes from your business (the Principal Entity) through each telemarketer (TM) to the operator. You declare that chain on your DLT portal. From 30th September, operators block traffic where the declared chain does not match the actual route, so this step matters as much as your templates.<\/p>\n

      The good news is that you set the chain once. When your SMS go directly through a registered TMD like Fast2SMS, the chain is short: your entity, then Fast2SMS, then the operator. Add the TMD ID on your DLT portal, send a test from the Shopify app, and confirm it shows as delivered in the Logs tab.<\/p>\n
