I was looking into the GDPR compliance requirements for Messenger Marketing and found this useful video from Isaac Rudansky talking specifically about MobileMonkey Bots.
“You are protected under Facebook’s own umbrella of compliance; A user clicking on the “Get Started” button implicitly states they’re okay with receiving messages from your brand”.
24 + 1 Rule = Within the first 24 hours of someone interacting with your bot you can send Unlimited Promotional and Non Promotional messages.
In the following 24 hours you can send 1 more non promotional message.
