As you can see, it takes just six simple steps for Clean Email to accomplish something that might take hours to do when relying only on the native features present in Windows Mail. That’s why, Clean Email can be your Windows Spam Filter tool, being able to stop junk emails automatically.

Does the Windows Mail App Support Email Filters / Rules?

No, the Windows Mail app for Windows 10  doesn’t support email filters/rules, and since Microsoft ended support for it, it can no longer send or receive email at all. If you would like to take advantage of them to better organize your messages, then you can use a third-party email client like Clean Email.

💡 Note! Support for Windows Mail, Calendar, and People ended on December 31, 2024.

Windows 11 now ships with the new Outlook as the default mail app, and Microsoft recommends switching to it or to Outlook.com.

Here is a video demonstrating effective techniques to manage spam and other messages in Outlook, helping you clean annoying emails.

Windows Mail Junk Settings

You can no longer mark emails as junk in Windows Mail. Microsoft ended support for the Mail and Calendar apps on December 31, 2024, and they can’t send or receive email anymore, so the app’s Mark as Junk option no longer reaches your mailbox.

Microsoft recommends moving to the new Outlook for Windows or Outlook.com. For Outlook.com, Gmail, and other IMAP accounts, the Junk folder is stored by your email provider, so messages you already marked as junk are still there when you add the same account to Outlook. Local emails, events, and contacts saved only in Mail can still be exported.

Unlike the Mail app, which only had basic features like receiving and sending emails, the new Outlook also supports email filters, also referred to as inbox rules, so you can move messages from persistent senders automatically.

For these and other reasons, the users of Windows 8, Windows 10, and Windows 11 should equip themselves with a third-party inbox cleaner like Clean Email. With its help, getting rid of unwanted messages and preventing them from ever again finding their way into your inbox becomes effortless.

Clean Email provides a wealth of useful inbox and spam management features that Microsoft decided not to include in the Windows Mail application for the sake of keeping it simple enough for casual users to get started within no time.

By default, Clean Email groups messages in the Inbox folder by:

FAQ

When does Windows Mail delete spam messages?

Windows Mail didn’t control this. For Outlook.com, Gmail, and other IMAP accounts, the Junk folder is stored by your email provider, so how long spam is kept before automatic deletion depends on your email provider’s settings.

What should I do if messages end up in the Junk folder by mistake?

If a message ends up in the Junk folder by mistake, you should move it to your Inbox or any other suitable folder to prevent it from becoming automatically deleted.
