Editors' Review

by   / October 01, 2014

SpamSieve integrates with many different mail programs to provide a more complete service to keep spam messages out of your Inbox. The more you use this program, the more effective it will be for you and the less likely you are to see unwanted messages or to miss those you do want.


Integration options: This app can integrate with all kinds of mail programs, including Apple Mail, Airmail, Mailsmith, Outlook, and more. You can also use it with Web-based mail services like Gmail, Yahoo, and AOL, and it's compatible with iCloud as well.

Increasing accuracy: Once you have this app installed, it will immediately begin to filter your messages. But if you just sit back and expect it to do its job, you probably won't be too impressed. It works fine without input, but the more feedback you give it, by marking junk messages that wind up in your Inbox as spam and important messages that wind up in your Spam box as reputable, the more you'll get out of the program. Through this feedback, it will become better and better at identifying and sorting your incoming emails until you won't have to worry about losing reputable mail to your Spam box again.


Complicated setup: Teaching the app what messages you want in your Inbox and which you don't does take some time and effort. And that's not the only investment of time you'll have to make in this program. Just setting the app up is somewhat of a complicated process, even with the detailed instructions.

Bottom Line

SpamSieve works well, and it's a good option to consider, especially if you find a lot of spam messages sneaking into your Inbox. It integrates with so many mail programs, and it does a good job of learning and adapting to your needs. You can try it for free for 30 days with all features active. To continue using it beyond the trial period, you'll have to pay $30 for a full license.

Editors' note: This is a review of the trial version of SpamSieve for Mac 2.9.16.

Full Specifications

What's new in version 2.9.37

  • SpamSieve is now compatible with Apple Mail under macOS 10.15 (which is now in beta).
  • Updated the documentation for macOS 10.15.
  • The Outlook - Filter Mailboxes app is now notarized for compatibility with macOS 10.15. If you've already installed the helper app, it should not be necessary to update it, but this change is needed for future updates as well as new installations.
  • Apple Mail on macOS 10.15 has a bug where it will not load plug-ins that are installed in the normal location if you've redirected your home folder to another volume. If SpamSieve detects this situation, it will apply a workaround (moving the plug-in to an alternate location) and show an alert that explains what it's doing
