How to be sure for deleting Google account instead of Gmail product

Question

A while ago I wanted to delete whole Google account(because it's recovery mail was a custom domain, and this domain is not used anymore so I don't want new owner of domain to recover this Google account). And I deleted account, but today my friend said that "you may be deleted only Gmail service and someone can login with alternate mail, so be sure that you completely deleted Google account not just Gmail".

When I try to login with ....@gmail.com and it says "This account was deleted". So how can I be sure that whole account has deleted or I just deleted Gmail account.

Edit: It's not a work/company account, it's an ordinary Google account.

Answer 1

When you go to https://myaccount.google.com/preferences?pli=1#deleteservices to delete your account, there is an option there to delete services¹ instead of your whole account. But it's a separate process. You'd know if you simply removed Gmail from your account.

A Gmail account is a Google account, so if you're trying to sign in and it's telling you the account is deleted, it's deleted.

Further, after 2-4 weeks, a deleted account is completely unrecoverable (short of a court order, and even then is probably a lost cause).

I don't think you have anything to worry about.
