There have been a couple of instances where the family has received the invitation email or text, and replied to it thinking the Funeral Home would receive the reply. That is not the Case. The Funeral Home isn't receiving information they may need, and the family may be thinking the Funeral Home is ignoring their messages.
The Invititation needs to be more clear that it is a No Reply message.
Could also include the Funeral Home's email and Phone Number for the family to make it easier.
