Many thanks to Aleksandr Romanenko for sharing these tips.
If you mainly use a non-Shoreline email account, these instructions show you how to have your Shoreline mail forwarded to that account. You can also set it up to send email from your non-Shoreline account, and make it look like it came from your Shoreline account. (That is the second list of instructions.)
I have not personally tested these instructions. Also, I am not a technical support staff person. Proceed at your own risk and your own comfort level with technical matters. If you need help, try your non-Shoreline provider. You can also try the Shoreline help line (206-546-5872; firstname.lastname@example.org).
These are basic step by step instructions to sending and receiving e-mail through a Shoreline account by way of an alternative personal e-mail. The Instructions for sending e-mail from an alternative account are slightly more complicated and only necessary if you are interested in sending e-mails from the Shoreline e-mail address using your personal e-mail account. I hope this helps.
(Only necessary if you wish to e-mail someone from your personal e-mail account using a shoreline e-mail address.)
