The supported keyword blocks this sender-and-subscriber pair. Carry the preference across the program the customer asked to stop.

Know the coverage.
Keep the preference.

Honor the choices customers make about your messages.

Check the country’s keyword rules.

Default handling covers a subset of countries. Read the applicable rules before relying on automatic replies or suppression. Where there is no coverage, your application must honor opt-outs.

Understand the suppression scope.

A recognized stop keyword blocks one sender-and-subscriber pair and sends a confirmation. Carry the customer’s preference across the program they asked to stop.

Keep incoming handling aware.

A stop message still produces sms.received. Branch on the keyword outcome before business replies. Custom replies can change wording while retaining the protected keyword behavior.
