You can delete Gmail from your Google Account at any time. If you're sure you won't use Gmail in the future, please follow these steps to delete it: Sign in to your Gmail account. Click on your name or email address at the top of the page, then select Account settings from the drop-down menu. In the "My products" section, click the Edit. Click Delete Gmail Service and fill in the required fields.
2. Click the Edit link next to the My Services list. (Upper right) On this page, you can delete your account. (You have the choice of deleting just your gmail account, or all Google services.)
3. Confirm your account deletion. You'll need to check these two options: 'Yes, I want to delete my account,' and 'Yes, I acknowledge that I am still responsible for any charges incurred due to any pending financial transactions.' (Please be assured that you can safely select the latter option if you haven't used any of Google pay services or if you have no pending financial transactions related to these services.)
