Use cases

What teams build with Relayion.

One API for the messages your business actually depends on.

Clinic appointment reminders

Send reminders from the clinic's own number. Patients already have it saved. Replies route back to your system.

Give your AI agent a real phone number. Outbound messages and inbound replies flow through the same API.

Confirmations and dispatch notifications from a number your customers recognise. Flat monthly cost.

Time-sensitive codes over a real SIM. One device, one number, multi-SIM fallback if needed.

Incident alerts and reply-based approvals over SMS. No app install needed on the receiving end.

Outbound promos from a local number. STOP and HELP replies route to your webhook for opt-out handling. Flat monthly rate.

Transaction confirmations and balance alerts from your own number. No shared short code, no third-party sender.

Attendance alerts, exam reminders, and announcements from the school's own number. Parents reply directly.

Assign jobs, share pickup details, and collect acknowledgements from drivers. No app required on the receiving end.

Reservation and appointment confirmations from the venue's own number. Cancellations and changes reply to the same number.

Free plan. One device, 500 messages per month. No credit card required.
