It becomes pretty tedious to keep clean.  That’s one of the many reasons why I use the Thunderbird email client. With a simple-to-use GUI, I can create specific filters for incoming emails to send those emails to certain folders. This feature is automated and works every time the client pulls mail from the server. Create enough filters and you can keep that main inbox considerably cleaner.

How to create message filters in Thunderbird to keep your inbox organized

So, if a full inbox gives you hives, this feature is right up your alley. Let me show you how to create a filter in Thunderbird.

Requirements

The only things you’ll need for this is Thunderbird installed on your desktop or laptop OS and a working, configured email account. That’s it. Let’s filter some emails. Also: How to encrypt your email and why you should  Also: The 6 best email hosting services 

Action: What to do with the messageLocation: Where to save the message

From the left drop-down, you can configure the filter to do things like move, copy, forward, mark as read, tag messages, and more. From the right drop-down, you select the folder that will house the message. You can also click + to add another action.  For example, your first action might copy the email to a specific folder and the second moves it to a different folder. This would be a great way to have a backup of all emails that come in from a specific contact and then keep those emails housed in their own folder. There are other options to choose from when creating your filter. You can specify how the filter is to be applied, filter before or after junk classification, and specify the exactness of the filter (should it match all of the criteria or any of the criteria).  Once you’ve configured the fitter to your specifications, click OK to save it. Thunderbird will automatically start applying the filter as mail comes in. That’s it, you’ve created your first Thunderbird mail filter. Keep creating new ones and your inbox will finally be clean enough to manage. Just remember, however, there’s probably unread emails in those destination folders… don’t forget to check ’em.
