I created my new married name account a few weeks ago, and now I'm trying to set it up for a seemless transition. It took me awhile to figure it out, so I thought I'd share the steps with you ladies!
If you want to forward mail from your old address to your new address, and be able to reply from either, you:
1) Create new email address
2) Log out - or preferably do it on different computers so you can keep both running simultaneously - then log in to old address, then click the little cog thing on the right corner, then "Settings".
3) Then click "Forwarding and POP/IMAP". On the first line, you'll see "Forwarding". Click "Add email account" and type in your new address. It will send a confirmation email to your new address.
4) In your old account, click "Accounts and Imports", and scroll down to "Grant access to your account". Add your new email address here. It will send another confirmation email to your new address.
5) Go to your new address. Open both confirmation emails and click the appropriate link.
6) In the new address, click the cog thing, then "Settings" then "Accounts and Imports".
5) Go down to "Send Mail As" and click "Add Email Address as Your Own". Then add your old email address. This will let you reply as your old address if you want to - if you want to just reply to all emails with your new address, you can skip this step.
There you go! It's a bunch of back-and-forth, but that should accomplish the main goals. Hope it saves someone some time! It was a bit confusing to do it myself. I plan to be able to reply from my old address for awhile, and then disable the reply from to transition fully to my new address.
