Looking for a way to set up a “Text ‘contest’ to xxx-xxx-xxxx to enter the drawing!” type of functionality. I’d like to see this as point of entry into campaign or segment.
Assuming this doesn’t exist- but I think this is a relevant feature. But, maybe it’s plugin facing since this is going to be SMS provider specific?
It sounds like you are looking for SMS reply detection which has been available since 2.16.0:
Docs are here: SMS Text Messages | Mautic
Just drop the user into a segment based on replies using the replied campaign action as explained in the docs, and use that to initiate a campaign if you want to start a campaign based on the reply
