Google has a policy of deleting accounts after they have been inactive for 3 years.
Google is not deleting old emails. Google’s Gmail service is a cloud-based email service, meaning that your messages are stored on their servers and not on your computer. This means that if you delete an email from your inbox, it will still be available in the trash folder.
Most email providers will suspend an account after a period of inactivity and require the user to log in before they can access it again. If the user does not log in, then their account is deleted.
Inactive email accounts are deleted after a certain amount of time. The length of time varies from company to company, but it is usually between six months and three years.
Gmail stores all email messages for at least six months. After six months, Gmail will automatically delete the message.
