Bulk SMS from WordPress: Send Campaigns with a Free Plugin

Your customer list is sitting inside WordPress. A festival sale is coming. You could export a CSV, upload it to some external tool, fix the number formats, and hope for the best. Or you could open a tab in your WordPress admin, pick a template, choose “all customers”, and press send.

The free Fast2SMS plugin gives WordPress and WooCommerce a built-in bulk SMS and WhatsApp campaign tool. This guide shows how to use it well.

What the campaign tool does

Audience in one click. Send to all WooCommerce customers, all WordPress users, or any pasted list of numbers.
SMS, WhatsApp, or both. Use your approved DLT SMS templates or WhatsApp templates.
Send now or schedule. Pick a date and time and the campaign fires on its own.
Fast at scale. Campaigns use the Fast2SMS bulk API, so thousands of messages go out quickly, with live sent, failed, and total counts.
Opt-outs respected automatically. Numbers on your do-not-send list are skipped every time.

Consent and the do-not-send list

Bulk messaging only works long-term with clean consent. The plugin gives you a “Send me order updates” checkbox at checkout and a do-not-send list in Settings. Campaigns, notifications, and OTP links all respect that list automatically, and phone numbers are stored encrypted and shown masked.

Frequently asked questions

Is the bulk SMS plugin free?

Yes. The plugin is free. Messages are billed to your own Fast2SMS wallet at your account rates, and bulk pricing is among the lowest in India. See DLT bulk SMS pricing.

How many messages can I send at once?

Thousands. The plugin batches through the Fast2SMS bulk API, which accepts hundreds of numbers per call, and shows live progress until the campaign finishes.

Can I schedule a campaign for later?

Yes. Pick any future date and time in the composer. Scheduled campaigns run on their own and appear in the logs like normal sends.

Do I need DLT for bulk SMS?

Yes, for SMS in India DLT is mandatory. Registration is a one-time job and Fast2SMS DLT support does the heavy lifting free.

Can I send bulk WhatsApp instead of SMS?

Yes. The same composer sends approved WhatsApp marketing templates, including image headers. WhatsApp needs no DLT, just Meta template approval.

Where do unsubscribes go?

Add any number to the do-not-send list in Settings, or let customers untick the consent checkbox. Every future campaign skips them automatically.
