GoodByEmail

This site is a gem for those of you who don’t delete your emails. They offer an AI that does a lot of number crunching on your inbox and securely identifies email senders that are using up your inbox storage quota, so you can see who your top inbox offenders are, their email addresses, the amount of storage they consume, and the number of emails you’ve received from them. You can then easily unsubscribe from unwanted mailing lists, further decluttering your inbox.
