Configure SMS Compliance Settings
What SMS compliance settings do
SMS compliance settings help your texts meet carrier and policy expectations by adding sender identification (your business name) and opt-out language (for example "Reply STOP to unsubscribe") when they're needed.
How they work
- First outbound message: the first text in a conversation automatically includes sender info and opt-out language. This happens even if periodic updates are off.
- Ongoing conversations: after the first message, the text isn't repeated unless you turn on Periodic Sender ID & Opt-Out Updates.
- Smart detection: before adding anything, the system checks whether your message already contains sender info or opt-out wording, so it isn't duplicated.
Configure the settings
- Go to Settings → Phone System → Phone Numbers.
- Click Advanced Settings.
- Find SMS Compliance.
- Choose your options:
- Add an opt-out message so the first message includes opt-out language.
- Add sender information so the first message identifies your business.
- Periodic Sender ID & Opt-Out Updates to repeat them in longer conversations.
- Customize the wording if needed, then save.
Tips
- Use the same business name as your A2P brand or toll-free verification.
- Keep the opt-out wording simple: "Reply STOP to opt out."
- Leave these settings on for marketing messages. Turning them off can increase filtering and complaints.
