Someone replies to a text meant to join your latest challenge, and instead of you manually adding their name to a spreadsheet, that reply can register them straight into My Challenge Creator. Mobile Message connects to My Challenge Creator through Zapier, so an inbound text can complete a signup without anyone touching a keyboard or copying a phone number across by hand.

Think about a five day challenge you are promoting by SMS to your existing list. A customer texts back to confirm they are in, and that reply registers them for the free challenge automatically the moment it arrives. Someone who has paid for the premium version and texts a different keyword can be registered for the paid challenge instead, keeping free and paid participants sorted from the first reply rather than sorted later by whoever gets around to checking the inbox.

This only works one way, from a text reply to a registration inside My Challenge Creator. It does not pull challenge progress or content back into Mobile Message, it simply means the moment someone replies is the moment they are registered, rather than waiting for someone on your team to notice the message and add them by hand once the rush of replies has slowed down.
