I have a Google Account where the primary email is a non-Gmail address. By accident, I added a (silly) Gmail address to this account. Now I would like to delete the silly Gmail address and replace it with a sensible one. I do not wish to lose this Google Account as it has many things I need to keep. So the question is: If I delete the silly Gmail name, will I lose the account?
Go to http://myaccount.google.com and Remove Gmail permanently. This will remove Gmail address as the primary email address of your account and later will allow you to choose another Gmail address, if you like to do so.
Once a Gmail address is added to a Google Account, it becomes the primary email address for that account.
Acording to Sign in to your Google Account with another email address - Accounts Help Gmail addresses can't be used as alternate email addresses.
Delete your Gmail address
- Sign in to My Account.
- In the “Account preferences” section, select Delete your account or services.
- Choose Delete products.
- In the “Delete a Product” section, select Remove Gmail permanently.
- Follow the onscreen instructions and select Remove Gmail.
Depends, if its the "main" email of the account it's impossible
but if you mean the "backup" email I'm sure you can reverse the progress shown HERE.
