I have some news to share with you about a little known feature you
may find very useful! You can now link another email address with any
of your current Google Accounts. This will automatically act as a
secondary email for all of the services listed under that Google
Account. In Google Groups, for example, if I add a second address, I
can then choose which address will be associated with each Group. When
you have that second address associated with an account, you can then
log in with either address.
To add an email address to a Google Account, follow the link below and
add an additional email to the account listed under "Google account".
If you want to add an email to another Google Account, simply select
You can't add an email address that is currently tied to a Google
Account. You can only add email addresses which don't have an account
linked to them. You also can't add a Gmail address to an account.
Once you do add that email address, you'll need to verify this email
through the email sent to that added address.
Please let me know if you have any questions about this by starting a
new discussion. Thank you!
