# Text Messaging & Compliance

> SUBLAKE Docs · Channels · https://sublake.com/docs/sms

SUBLAKE handles the rules of texting so you don't have to.

## Opt-out is automatic

- A customer who replies `STOP` (or `UNSUBSCRIBE`, `END`, `CANCEL`, `QUIT`) is opted out immediately, with a confirmation
- Replying `START` opts them back in
- Replying `HELP` returns help information
- Keywords are case-insensitive and work in English and Spanish

## Transactional texts

Reminders and confirmations are sent in response to a booking or a message the customer sent first, and your business name appears in the text so customers always know who it's from.

See the Messaging (SMS) Terms for full details.
