In Text In Church, we allow you to see a full message history with any person record in your account. You can see both the outgoing and incoming text messages as well as any outgoing emails and when they joined a group.
To see the whole message history with a person:
Step 1: Go to People
Step 2: Click on the person you want
Step 3: Click "View Conversation History" under their name
Then you are directed to their conversation inside of the Messages tab where you can read and also respond via text as needed.
