If someone replies to a mass (or group) text, the replies ARE NOT seen by the other people in that mass message. It DOES NOT work like a group message on your phone.
For example: You send a message to the Monday prayer group which has 10 people in it. One of those people sends a response. Only 'you' see it. The other 9 people in the group do not.
MORE INFORMATION ABOUT WHAT 'YOU' MEANS
All responses come back to the INBOX in your PastorsLine account. Any user that has access to the number and/or group would see the message. This is based on user roles. So who sees it in PastorsLine is dependent on their role. More details about user roles HERE.
