SMS Signature

SMS Signature automatically appends text to the end of every outbound SMS you send. Use it for company branding, agent identification, or compliance text like opt-out instructions.


Set Up an SMS Signature

  1. Go to SettingsSMS/MMS.
  2. Find the SMS Signature section.
  3. Enter your signature text.
  4. Click Save.

Example signatures:

  • — Team at Acme Inc.
  • Sent by {{agent_name}} | Reply STOP to opt out
  • Acme Support | acme.com/help

How It Works

  • The signature is appended to every outbound SMS from the configured number or agent.
  • Signature text counts toward your message character limit and may increase segment count.
  • Keep signatures short (under 30 characters) to minimize cost impact.

Auto-Add Signature

To automatically include the signature on all outbound messages:

  1. Go to SettingsSMS/MMSAuto-add signature.
  2. Toggle on.

When disabled, agents can still manually add the signature by selecting it from the compose area.
