How the SMS & MMS integration works

Inno Message adds SMS and MMS as a two-way channel: customers text your number, the message lands in the shared inbox, and agents reply as they would on any other channel. Your systems can also send transactional texts such as reminders and alerts through the API, and replies come back to the same conversation.

Who it's for: Teams that need to reach customers on any phone, and anyone sending reminders or alerts.

Two-way by default

Replies to reminders and alerts arrive in the inbox instead of disappearing.

Send from your systems

Trigger texts from your own software through the REST API.

Automated follow-up

Keyword rules handle replies like "YES", "STOP" or "RESCHEDULE".

Set it up

  1. Add a sender

    Connect an SMS-capable number or sender ID for the countries you message.

  2. Set opt-out handling

    Configure STOP keywords and consent rules required in your markets.

  3. Start sending

    Reply from the inbox, or send transactional texts through the API.
