"Clean Email" is a cloud-based software that can be used to automatically unsubscribe from spam emails, filter emails into folders, block, and trash old emails in your inbox. It also allows users to create custom Auto Clean rules to mark particular messages as read, "keep newest," pause, and move to custom folders. It has received positive reviews from users, with an average rating of 4.4 out of 5. Users have praised its functionality and the ability to clean up tens of thousands of emails with a few clicks. However, some users have mentioned that some functions are not intuitive and take some time to understand. It is considered safe, and the credentials are always encrypted and never available to anyone. It offers a free version, but there is also a paid service available for $49.99/year, which provides coverage for five email accounts. It is compatible with Gmail. However, if you have a relatively new email account or only get a few emails a day, you might be better off using built-in tools from your email provider to keep it clean.
