Hello @mmedwid, and thanks for reaching out to the AT&T community for help!
We don't have the ability to to reroute SMS from your line to an email address, however messages can be sent to email messaging from almost all phones by typing the address into the field in place of the phone number.
You can also check out our AT&T Messages Portal to learn how to back up and sync your messages to any device.
We hope this helps, and you have a great day!
Dwight, AT&T Community Specialist
