Receiving Google Groups mail at my personal Google Account
If you're suddenly receiving mail from Google Groups to the primary email address listed on your personal Google Account, this is because you're unable to use your @mydomain.com address as an alternate email addresses.
If your work, school, or other group signs up your @mydomain.com domain for G Suite and you previously had the @mydomain.com address listed as an alternate address on your personal Google Account, the address will be removed as an alternate email address on any Google Accounts you've set up. If you've set any groups to send email to your alternate email address, emails from Google Groups will now be delivered to the primary email address on your Google Account.
To change your email settings:
- Log in to Google Groups.
- In the top left, click "My Groups."
- Next to the group you want to change email settings for, click Edit.
