Gmail plans to start permanently deleting inactive accounts on December 1. Since November is almost over, we decided to give you one final urgent reminder to log into your old burner accounts to make sure they survive the Great Google Purge.
If you have an old Gmail account lying around that you haven’t used in a while, make sure to use it before December 1, or Google will permanently delete it. By ‘in a while,’ Google means two years. That’s the criteria they have set for the amount of time that should have passed for them to consider an account inactive.
