SpamSieve overview

SpamSieve is a robust spam filter for major email clients that uses powerful Bayesian spam filtering.

SpamSieve understands what your spam looks like in order to block it all, but also learns what your legitimate messages look like to avoid confusion. SpamSieve only marks spam in your email client so you never lose any mail.

The following is a partial list of SpamSieve’s features, so that you can quickly see what it can do and how it’s unique:

  • Powerful Bayesian spam filtering results in high accuracy and almost no false positives. It adapts to the mail that you receive to get even better with time. Some other e-mail programs include Bayesian filters, but SpamSieve is more accurate.
  • Integrates with your e-mail program for a superior user experience. Plus, you get the same great filtering if you ever switch e-mail programs or use more than one at a time.
  • SpamSieve works with any mail provider/host. It filters all your mail accounts. There is no extra charge for additional addresses or devices.
  • SpamSieve running on your Mac can keep the spam off your iPhone/iPad, and you can even train SpamSieve from afar.
  • Colors show how spammy each message is, so you can quickly focus on the borderline ones if you want to check SpamSieve’s work.
  • Integrates with the macOS Contacts app (and also Eudora’s and Entourage’s address books) so that messages from friends and colleagues are never marked as spam.
  • Automatically maintains a blocklist so that it can instantly adapt to spam messages sent from particular addresses, and catch 100% of them.
  • Automatically maintains a whitelist to guarantee that messages from particular senders or mailing lists are never marked as spam, without cluttering your address book with these addresses.
  • You can customize the whitelist and blocklist, adding sophisticated rules that match various message headers, or the message body. The rules can match text in a variety of ways, including using regular expressions.
  • Can use the Habeas Safelist, which indicates messages that are not spam, as well as the "ADV" subject tag indicating that a message is spam.
  • Many spammers encode the contents of their messages so that filters cannot see the incriminating words they contain. SpamSieve can decode and look inside these messages. Optionally it can mark them all as spam, on the theory that legitimate senders do not try to obscure their messages.
  • SpamSieve keeps track of how accurate it is, how many good and spam messages you receive, and how these numbers change over time.
  • Turn off new-mail notification in your e-mail program, and let SpamSieve notify you only when you receive non-spam messages.
  • The corpus window and log let you see how each spam message was caught.
  • Unlike server-based spam filtering services, your mail data stays on your own Mac, so your privacy is preserved.
  • SpamSieve supports AppleScript, so you can connect it to additional apps and fully integrate it into a custom workflow.

What’s new in version 3.0.3

Updated on Dec 27 2023

SpamSieve 3.0.3 is a free update for those who have already purchased the SpamSieve 3.0 upgrade. If you’re using SpamSieve 2 and haven’t upgraded yet, the easiest way is to first let SpamSieve install the new version. At launch, it will show the Purchase window, and you can click the Check Upgrade Options button to get the upgrade discount without having to enter your old serial number.

Apple Mail
  • Fixed a problem where, with certain unusual account configurations, SpamSieve would not see the new messages that needed to be filtered, so they would stay in the inbox.
  • SpamSieve is better able to continue filtering messages when Mail is temporarily unable to look up account information.
  • Worked around a macOS bug that could cause Mail to hang if it was preparing to send a message to the SpamSieve Mail extension while SpamSieve was filtering another mailbox.
  • Improved the Filter spam messages in other mailboxes feature:
    • Added a safety feature where SpamSieve will no longer filter messages that were received before SpamSieve was installed or before this feature was activated, to avoid reprocessing lots of old messages that happen to still be marked as unread.
    • The checkboxes in the mailbox list for TrainGood and TrainSpam are now disabled, as these mailboxes should not be selected for filtering.
    • SpamSieve is now able to continue finding mailboxes to list even if Mail returns invalid information for some of them.
  • Fixed a bug where the Settings ‣ Apple Mail ‣ Training window could be out-of-sync with the stored settings that SpamSieve was using, leading to trained messages not moving where you expected.
  • Removed the Including in the inbox setting. The Add green flag to unread good messages setting now controls the green flags for all mailboxes.
  • Improved the error handling when reading the selected messages.
  • Improved the error handling when reading the inboxes.
General
  • Worked around a macOS bug that could cause a crash when updating the Dock icon.
  • Worked around a macOS bug that could cause SpamSieve to hang at launch or when opening the Settings window.
  • The Print… command is now disabled for large table views, as it would overload the macOS printing system and cause a hang.
  • Improved the following sections of the manual (amongst others):
  • Fixed a bug where a damaged corpus database could cause a crash.
  • Fixed a bug where the hotkeys didn’t work with certain keyboard layouts.
  • Fixed a bug reporting errors during Outlook filtering.
  • Worked around a Core Data bug that could cause a crash.
  • Updated the German localization.

This app has tremendous value especially when we get inundated with spam. To date it has trapped all mail not based on my whitelist. It easily lets you identify what it might have considered spam by telling the system that particular mail was "Good". And the most important thing was when I had a learning issue, the support was fast and phenomenal. The developer was johnny on the spot helping me learn what I did to cause the issue. I highly recommend this app for those of you sick of being spammed and phished.

If you have old email addresses that are literally bombed with spam, SpamSieve is a godsend. But the trouble with spam is that it will never end and that you can't avoid checking false positives or negatives. I've tried to stick for years to the typical jefferson.smith@senat.com (sample ;)) but in the end I reluctantly had to change my address. Spammers mostly use the same old databases, so if your address was created more than ten years ago, you're very lucky if it's not in those databases (same for your old password if you never changed it). Sometimes it's better to cut a leg than to try and cure it...

For me, it didn't work. I even copied into the Blacklist of the application about 90 addresses that send me SPAM. Well, it's stayed just the same as before. I complied point by point with the fairly complicated instructions, and... nothing.

This just flat-out works. I have had the same email address since there was email, so I get a ton of junk. It would take several minutes a week to sort through it all and it was very frustrating. Now, SpamSieve just handles it all. While not perfect, my guess is that the accuracy is at least 95%. In the past, I had to look at my Inbox and sort through all the junk. Now, I will check the SpamSieve junk folder, and see if anything that is not spam was inadvertently classified as spam. It happens rarely, but this is so much of a faster process, that it typically only takes me 15-20 seconds a day. Worth every penny!

As so many of these reviews have cited, SpamSieve is the best spam filter on the market. My experience with the software not only confirms that of other users but adds another dimension. When I had difficulties with Mail on my iMac, multiple senior advisors from Apple were unable to solve the problem. Desperate for help (I did not want to follow the latest senior advisor’s recommendation to reinstall the OS and all of my third-party apps), I turned to SpamSieve’s support for help. By far, this has been my best support experience with my computer. The expert who responded to my many emails did so with abundant patience and skill—during a holiday weekend, no less. For the first time in months, my Mail client is running smoothly.

I have been using SpamSieve on my Macs for over 15 years. Given its cost, that works out to about $2 per year. And it has certainly saved me more than that in time spent cleaning up my mailboxes! It works, like a Mac application should: seamlessly and unobtrusively. Out of the box it's a terrific helper, but if you spend time "training" it, it really shows its magic! I once went overboard and got too "deep into the weeds," but SpamSieve even has a way out of that (e.g., "rebuilding the corpus"). SpamSieve is one of those I-can't-do-without programs, and the one-time charge is well worth it!

I’ve been using SpamSieve with “Airmail” since the developer made it compatible with this emailer. Something I’ve noticed and you probably know, is that the more you use it, the better it becomes in distinguishing “spam” from authentic mail. It does this by learning the pattern of junk mails you receive and not by simply identifying and blacklisting their senders. Therefore, after a week or two no spam passes through if you correctly blacklist spam in the first place. I still receive junk mail, but it’s limited to 10 mails a month and not 100 a day like before! The developer has done a great job by making it compatible all major emailers and not solely with Apple Mail. In this way, even if you change your emailer, your blacklists will also be transferred to the new one. I can’t remember the last time I paid for an upgrade but in the market of applications that work on a subscription basis it’s rare to find a developer that instead of seeking new strategies to increase his profits prefers to spend his time on enhancing his software and making it more efficient for all users alike. Thank you very much sir and please continue like this. Fariborz AMIRSHAHI – Verona (Italy)

After linking to an insecure network overseas, I was getting a hundred or more spam messages every day, many of them offensive. With SpamsSieve, they're gone. You do need to follow the installation instructions precisely. And... do take the time to train the software to recognize your particular flow of spam. (It's all there is intro well-written but lengthy step-by-step instructions.) It's also important to monitor the Spam folder every day for the first couple of weeks or so to catch false positives and train SpanSieve to not delete a few specific email senders. (using version 2.9.36 - June 2019) You may need to switch your iPhone/iPad email from "Push" to "Fetch every 15 minutes" for new mail. That way, your Mac will discard the spam before it gets to your mobile device. The downside is that there can be as much as a 15-minute delay on your mobile device unless you go to settings and fetch manually when you're expecting an urgent email.
