This changes the reply-to of all emails so that email responses automatically come back to our server.
For Example: firstname.lastname@example.org would change to email@example.com
This is the recommended set-up and allows emails to be sent without the use of Subject Tags or a BCC Recipient.
While Email Address Mapping proves to be most beneficial, some Senders still want their email to be recognizable to the Recipient.
This will increase deliverability and user acceptance as emails come from your email address and not the mapped address.
It is possible to turn off Email Address Mapping however, it is NOT recommended.
Read Turning Off Address Mapping for more information.
