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
- Go to Settings → SMS/MMS.
- Find the SMS Signature section.
- Enter your signature text.
- Click Save.
Example signatures:
— Team at Acme Inc.Sent by {{agent_name}} | Reply STOP to opt outAcme 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:
- Go to Settings → SMS/MMS → Auto-add signature.
- Toggle on.
When disabled, agents can still manually add the signature by selecting it from the compose area.
