Can you customize the HELP/STOP messages for SMS filtering?
By default, Twilio handles HELP, STOP and other keywords when users text them into your Twilio phone number. This is to help ensure that your app complies with recommended practices for the commercial use of SMS. For details, please see this page in our FAQ.
We do not have a way for developers to customize the specific replies used in SMS filtering. If you have further questions about this, just contact us.
