Can I receive the reply message if the Reply-To field is NULL?
Yes, you can receive the reply message. The reason to leave the field empty is that most email software will check the ‘Reply-To’ field, and use the address in the field for reply. If the field is NULL, the address in ‘From’ field will be used. If you want to set the ‘ Reply-To ‘ field, follow the format below, or you can’t get reply message. It’s better to leave it empty.
