Overlays: Opt-in rules

You can apply different opt-in rules (i.e. double opt-in or single opt-in) to each of your overlay versions - or you can set a default in the blueprints.

Set up your opt-in rules per country in your Channel settings.

Double opt-in is considered best practice in most markets, especially when collecting phone numbers for SMS marketing.
