Info

If you use Twilio's default opt-out or advanced opt-out, you do not need to submit opt-out and help keywords and messages when creating a Campaign. Twilio will automatically complete those fields for you with the default or your advanced opt-out and help messaging.

If you manage opt-out and help yourself, you must pass the opt-out and help parameters when creating a Campaign.

Danger

Deleting an approved UsAppToPerson resource blocks all A2P 10DLC messaging from the Messaging Service.

You must create a new UsAppToPerson resource and wait for the associated Campaign to be approved by TCR in order to send A2P 10DLC messages from the Messaging Service again. This can take several days.
