Who we are

A messaging company built for small and large businesses alike

We started in 2011 because sending an SMS to customers was harder and costlier than it should be. Fifteen years later the same idea runs the company: a clear price, a panel anyone can use, an API developers like, and a team that helps with the paperwork. Schools, hospitals, shops, start-ups, government departments and listed companies all use the same account type and pay the same published rates.

How we work

What you can hold us to

Reliability first

Direct operator connectivity and routes we monitor around the clock, so OTPs land in seconds and campaigns finish on time.

Transparent reports

Every message shows its status and, when it fails, the reason. You see what we see, in the panel and over webhooks.

Support by real people

Chat inside the panel, a phone number that is answered, and email replies within the day. DLT questions included.

Security you can verify

ISO 27001 and SOC 2 Type 2 certified, VAPT tested, with data encrypted in transit and at rest.

Data security

Your data is encrypted and stays yours

Your customers' numbers and messages are business data. We treat them that way: encrypted on the wire and in the database, visible only to the people you allow, on infrastructure that is audited every year.

See our certificates

Encrypted in transitEvery panel page and API call runs over HTTPS (TLS 1.2+). Your API key is sent in a header, never in a page.
Encrypted at restSensitive fields such as contact lists, message content and reports are encrypted in our database, with keys kept outside the application.
Access you controlPer-user API keys you can rotate any time, IP allow-listing, OTP on login, and agents who see only what you assign.
