Give the reply a clear purpose
A Story can invite a simple question or request. When someone replies with text, a configured RelayDM automation can evaluate that incoming Story reply and attempt an appropriate private response. The best opening message refers to the resource or topic shown in the Story.
Keep the matching deliberate
Choose whether the journey should respond to eligible Story text replies broadly or only to configured keywords. Test with the actual Story and account. Non-text attachments and provider restrictions should not be assumed to behave like a supported text reply.
Offer one next step
A concise answer or a configured link to a resource is more useful than a long generic sales message. If the reply needs a personal answer, leave room for a human handoff rather than treating automation as a substitute for conversation.
