We enabled the SMS Opt-In block for all customers in the Forms composer. This allows all customers, not just those with the SMS Add-On feature, to collect SMS Opt-Ins.
Because explicit opt-in are required before sending SMS messages, this allows customers to begin collecting opt-ins before activating the SMS message feature.
For more information on SMS Opt-Ins, see our SMS Opt-In Guide.
The SMS Opt-In block appears in the upper left set of drag-and-drop blocks in the Forms composer.
You can customize the default Opt-In block text.
