SMS Step

Send a text message at this step.

What this step does

An SMS step sends a text message to the contact when they reach this step in the flow.

1

Add an SMS step

Add an SMS step where you want the message to send.

2

Choose the message

Select the SMS program the contact agreed to, choose a ready sender for the same business identity, then write the message.

3

Test with one contact

Trigger the flow once and confirm the message sends.

When to use it

  • Appointment reminders
  • Short follow-ups
  • Time-sensitive alerts

Tips

  • Keep messages concise.
  • Review the final policy preview and segment count. Shorten the message or explicitly allow multiple segments when the final text needs more than one.
  • A contact must have valid permission for the selected program and no active opt-out or do-not-contact block. The sender must also be active and ready.
  • If consent, suppression, phone, or sender checks fail, the step safely skips that recipient rather than sending from an unready path.
  • Test with a single contact before turning the flow on.

For timed reminders, pair this with Wait Until. Use the Twilio guide for setup and sender checks. To collect permission on a published page, see the

Form guide.
