March 2016 - McSolo recommends SpamSieve:
Simply put, this app works better than SpamAssassin, and unlike the Junk mail filter in OS X’s Mail, it gets better over time. […] If your email accounts are IMAP, the offending and unwanted messages are stored in a separate folder on your Mac and that keeps them off your iPhone and iPad, too.
March 2016 - Markus Ostermeier reviews SpamSieve (German).
January 2016 - Mój Mac Magazyn (p. 72, Polish) reviews SpamSieve and rates it 5/5.
December 2015 - Macworld reviews SpamSieve, calling it a “must-have”:
Years ago I decided that I prefer using software on my Mac to filter spam. C-Command Software’s $30 SpamSieve has been around since 2002 and is hands down the best spam filtering software for Mac. Unlike the brute-force filters on servers, SpamSieve learns from your email. If you get lots of emails that contain certain words, SpamSieve learns that these are normal, and sends them to your inbox. However, if spam gets through, you just select one or more messages and press a keyboard shortcut to tell SpamSieve that they are spam; the app learns from that too. And it’s incredibly accurate. […] This app works so well that, over time, you almost forget about it.
December 2015 - About.com recommends SpamSieve:
SpamSieve from C-Command is by far one of the most powerful spam filtering systems available for the Mac. […] I found SpamSieve easy to set up. Its spam learning system was easy to train, and much quicker and more accurate than Apple Mail’s built-in spam filtering system. In fact, Apple Mail and SpamSieve make very powerful partners for fighting spam.
November 2015 - Macworld recommends SpamSieve as one of “10 essential Mac utilities”:
I get lots of email, and much of it is spam. I’ve tried using server-side spam filters, but there are too many false positives; messages marked as spam that aren’t. To tame my email, I use SpamSieve, a simple utility that works in the background to filter all my email as it arrives, and sort the wheat from the chaff.
November 2015 - Dan Counsell recommends SpamSieve as a world-class application that’s sold outside the Mac App Store.
August 2015 - Ryan Cash’s profile in The Sweet Setup recommends SpamSieve:
I recently purchased SpamSieve to help me keep my inbox in Apple Mail clean – it was getting out of control, and Apple’s junk filters don’t seem to work as well. It was totally worth the purchase.
July 2015 - John Castle recommends SpamSieve:
The combination of Airmail 2 and SpamSieve carries with it *phenomenal* spam-blocking power, and delivers it through a stylish, minimal, functional and above all *intuitive* interface that Apple’s Mail — and all Mail’s other competitors — simply do not even approach, let alone match.
June 2015 - Tera Talks recommends SpamSieve:
Years ago I switched to SpamSieve and unlike Mail’s Junk Mail Filter, this one seems to get smarter over time, though it requires occasional training episodes. Installing SpamSieve is straightforward, and it works right out of the box, though tweaking is in order because it does learn the kind of spam your accounts receive.
June 2015 - cuk.ch recommends SpamSieve (French).
June 2015 - The CapMac Users Group recommends SpamSieve:
Harvey Rubinstein will discuss the benefits of using SpamSieve, along with its installation, set-up, features, and how this spam, phishing, advertising, & malware controlling application can give you back your Inbox.
SpamSieve uses powerful Bayesian Spam filters to detect incoming spam, and adapt to new spammer tricks to block those too. It can even maintain a whitelist to ensure that none of your legitimate emails get tagged as spam.
June 2015 - MacLife.de (p. 92) recommends SpamSieve (translated from German):
The additional spam filter SpamSieve is one of the best add-ons for Apple Mail. Installation is simple and if you train the application with some examples of which messages are spam and which are desired, the hit rate of the software is impressive.
SpamSieve can outsmart serious-looking emails with dangerous attachments, since the software also analyzes these. You can use a slider to adjust how rigorously SpamSieve filters, and the results are impressive.
November 2014 - Mac360 reviews SpamSieve:
Easily the premiere spam catching filter utility for the Mac is SpamSieve; an app I’ve used for years with great results.
September 2014 - Yahoo News reviews SpamSieve:
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.
August 2014 - Ben Brooks reviews SpamSieve:
For a $30 app, this seems like an absolute steal of a deal for a problem that almost everyone faces. If you use email, I highly recommend SpamSieve.
July 2014 - MacLife (p. 79) recommends SpamSieve:
The built-in Mail spam filtering that is included with Apple Mail is […] not the best that’s available. However, there’s an easy-to-use plugin that is available for Mail that allows for better email spam filtering. The plugin is called SpamSieve.
July 2014 - David Bosman includes SpamSieve in his list of essential apps (French):
Payer pour un filtre antispam ? Oui. Je ne l’ai découvert qu’il y a quelques mois, mais, enfin !, consulter ma boite aux lettres n’est plus une corvée : (presque) zéro spam. Une efficacité bluffante qui vaut largement son prix.
June 2014 - Ask MetaFilter recommends SpamSieve:

April 2014 - Macworld Sweden recommends SpamSieve.
April 2014 - Kafeneio recommends SpamSieve:
SpamSieve is very easy to train and it remembers. If you have some spam emails in your Inbox or JunkMail, you point SpamSieve to it and it uses them to train itself. It is uncannily good at catching crap, and once you train it on the ones that manage to sneak by, it catches them faultlessly in the future.

I wouldn’t even think about using Macintosh e-mail app unless it’s supported by C-Command’s SpamSieve by Michael Tsai. This app has changed my computing life greatly for the better, and I love it. SpamSieve uses Bayesian filtering to build a corpus, and it learns as it goes. The longer you use it, the better it gets at filtering out spam. These days, SpamSieve is filtering out about 50 spam messages a day with just about perfect accuracy.

November 2013 - David Sparks writes in The MacSparky Email Field Guide:
SpamSieve is the premier spam software for the Mac. This has been true for a long time. Every few years I survey the field of other spam applications on the Mac and every few years I come back to the conclusion that this is a one-horse race.
If you’re having trouble dealing with spam on your Mac, go directly to SpamSieve and install it on your Mac.
October 2013 - Mac 360 reviews SpamSieve:
For most of the 21st century I’ve relied on SpamSieve, and add on utility that works much like [Apple Mail’s Junk Mail Filter], only better. Actually, much better. […] If spam is a problem for you on your Mac, SpamSieve could easily be the answer.

October 2012 - OS X facile reviews SpamSieve:
Que faire ? Je vous conseille d’opter pour “SpamSieve,” qui non seulement est en français, mais est extrêmement simple dans son fonctionnement et en plus donne d’excellents résultats avec une visibilité facilitée. Si la fonction “Indésirable” de “Mail” ne vous semble pas suffisante ou peu adaptée pour venir à bout des nombreux spams que vous recevez, “SpamSieve” devrait pleinement vous satisfaire.
September 2012 - Macworld’s Enhance and extend Mail at a discount writes:

September 2012 - Mac306 reviews SpamSieve:
Your mileage may vary, of course, but my success rate is right around 99-percent and false positives for the past year can be counted on my fingers.
SpamSieve is hands down the best spam filter out there…If you don’t have it, get it.
August 2012 - WoowooMac recommends SpamSieve:
Install SpamSieve and you will rid your inbox of spam. Really, it just works. SpamSieve learns and adapts to your mail, so it’s able to block nearly all the junk without putting good messages in the spam mailbox.
My home iMac is continually checking my email. SpamSieve on that machine is continually processing the email, moving any messages it thinks are spam to the “Spam” folder — keeping my inbox pretty much spam-free for my MacBook Air, iPhone and iPad.
July 2012 - Gear Live recommends SpamSieve:

June 2012 - Joe Kissell’s Take Control of Apple Mail with Lion e-book recommends SpamSieve:
If […] you get too much spam in your Inbox, you need a third-party anti-spam utility to beef up Mail’s defenses. There are several good choices, but my favorite is Michael Tsai’s $30 SpamSieve. It’s freakishly accurate and, for heavy email users, money extremely well spent.
May 2012 - John Siracusa on Mac Power Users podcast #87 says (audio starting at 1:04:54):
The Gmail spam filtering is vastly inferior to SpamSieve, which is what I use locally to filter my mail.
May 2012 - The New York Times mentions SpamSieve.
April 2012 - Bohemian Boomer reviews SpamSieve:
Once you setup SpamSieve it’s mostly set it and forget. If an email spam gets through, use the pull down menu in Mail to train the massage as spam. If you find a legitimate message is marked as spam, again, train it right within Mail. It’s a click.
Whatever the folks who make SpamSieve are doing, it works. The price is modest (Apple’s built-in Junk Mail filter is free, but problematic at times) and updates are frequent.
April 2012 - SpamSieve is Tom’s Mac Software Pick at About.com:
What separates SpamSieve from many of the spam filtering systems built into email clients is how simple it is to set up and use. It also works better than most built-in systems.
March 2012 - Christopher Breen’s Dealing with spam when Mail won’t cut it in Macworld (June p. 84):
The other option is to forget about creating rules and lists and instead get an effective anti-spam utility. And when I say effective I do mean C-Command Software’s $30 SpamSieve (5 mice). We don’t dish out five-mouse ratings lightly, but in this case it’s completely deserved. I’ve relied on SpamSieve for years as have many of my colleagues. It really is the best way to deal with this crud.
February 2012 - Cult of Mac includes SpamSieve in its list of 50 Mac Essentials:
If you use Mail, you probably know it has its own spam-zapping feature, which is pretty good, but a long way from perfect. SpamSieve is the professional compared to Mail’s enthusiastic amateur. Once installed, it fiercely protects your inbox from the spammers, but still gives you control.
If you are being plagued by junk mail and Apple’s junk mail filter just ain’t cutting it, I cannot give a higher recommendation to Spam Sieve, as I value it as an essential piece of software. I convinced my skeptical IT department to adopt it and buy a site license for all Small Dog employees. It is just that good, and will give you that most precious gift—time.

When I say I had a lot of spam to handle, I’m talking about 50 an hour.…My experience of spam handling software was limited to Outlook, and my opinion was it wasn’t that good.…At the point I decided I was moving to the Mac…I setup a few Gmail accounts ferrying mail from one to the other to try and reduce the amount of spam I was getting. But I can’t get it down to nothing…I was still getting about 300 a day. And that’s when I came across this product called SpamSieve. I had a go with just the junk mail filtering that was in Apple Mail. And, no, it couldn’t really cope. It was making mistakes, both positive and negative.…Over time with SpamSieve, things get better. It learns.…It’s very very clever, and yet it’s pretty simple in use.…I haven’t seen one spam message in my inbox in two months. I haven’t seen one false positive in that long, either.
October 2007 - Rubin Recommends recommends SpamSieve:
…since phones don’t have junk mail filtering it’s amazing to use this. All you do is open your mail client a few times a day or at the end of the day and if you’re using IMAP it will suck all the junk mail messages out and off the server so when your phone goes to check it, it’s only the messages you want. Also you don’t have to spend time tidying up your Phone’s inbox because at the end of the day you can open your mail client and it will clean it up!

SpamSieve—$30 from C-Command Software—is recent discovery of ours. We have been trying a number of spam-filtering techniques here at Karelia, and nothing has even come close to this gem.

March 2007 - The Seattle Times recommends SpamSieve:

SpamSieve is the best spam filter for the Mac. It’s incredibly accurate yet invisible. I have been using it for almost three years now and its statistics show that over that time it was 99% accurate. SpamSieve is so invisible and maintenance free that I’ve just about forgotten about it—despite the fact that my e-mail has been widely posted on the Web for 10 years.

- December 2006 - The MacReviewCast names SpamSieve one of the top 10 shareware apps of 2006 (audio starting at 9:30):

Spam is an unfortunate fact of life…or is it? It hasn’t been for me in almost a year. I’ve abandoned the junk filter in Apple’s Mail app in favor of Michael Tsai’s SpamSieve. It’s incredibly accurate and really is the best spam filter I’ve ever used. No mac should be without this! It’s got a low $30 price tag for so much power.
November 2006 - ScreenCastsOnline shows how to use SpamSieve with Apple Mail.
November 2006 - The Mac Observer reviews SpamSieve 2.5 and rates it “Outstanding”:
Why bother buying an extra application when Mail and Entourage have their own built-in spam filtering features? Simple: Because SpamSieve does a better job. If you get lots of email messages, and lots of spam along with them, SpamSieve is a must have application.

May 2006 - .net Magazine reviews SpamSieve (page 60):
We don’t usually get excited about spam filters, but we’ll make an exception for SpamSieve. This OS X spam-killer plugs into most major OS X clients (including Entourage) and does a sterling job not just of zapping spam, but also of making sure that legitimate messages don’t get zapped by mistake.
- May 2006 - About.com reviews SpamSieve 2.4.3.
- April 2006 - David Pogue recommends SpamSieve in his New York Times e-mail column:
Spam Sieve is just incredibly, amazingly accurate; my In box is clean, baby, clean!
Once or twice a day, I take a look at my Junk Mail folder and literally grin with glee. There they are, all together, stewing in their own sleazy juices: all the ads for Viagra and Cialis; all the stupid phony phishing e-mails from eBay, PayPal and Chase Bank; all the foreign-language spam; all the messages that contain nothing but a big pasted graphic ad for pills; and on and on.
And in about 2,000 spam messages flagged so far, I’ve encountered not a single legitimate message flagged as spam. Now THAT is a great feature.

If I could have only one third-party Macintosh application, it would be SpamSieve.
- May 2005 - iCreate #18’s “50 Must-Have Mac Apps” cover story includes SpamSieve:
Almost all mail applications, including Entourage and Mail, have their own built-in spam filters. Some are better than others but almost all can be improved upon. SpamSieve [is] an even more effective spam filter [than Apple Mail’s]. After a bit of training, false positives and negatives tend to go away, leaving you with an inbox untained by herbal Viagra and requests to confirm your Bank of Washington security settings. Since Tsai updates the product frequently, SpamSieve is often ahead of the built-in junk filters and in keeping up with spammers’ latest techniques. Better still, it gives junk filtering abilities to email programs that never had the ability to spot junk mail.
- April 2005 - The Apple Blog reviews SpamSieve 2.3:
[SpamSieve] is the answer to spam on Mac OS X.…I don’t normally go for shareware in the fairly rarefied over-$20 realm, but SpamSieve is absolutely worth it. Eudora users will find it half the cost of an upgrade to Eudora’s Paid mode (which is required to use the vastly inferior built-in junk mail filters). SpamSieve will pay for itself within a month by freeing you from worrying about whether or not your junk mail filter(s) caught anything important.
- March 2005 - Jason Fried at 37signals recommends SpamSieve:
SpamSieve (Mac OS X) is the best spam filter I’ve ever used. Unreal accuracy and it keeps getting better. So far it’s 99% accurate over 8000 messages. Really great.
- February 2005 - SpamSieve is on Daring Fireball’s short list of Apps of the Year, 2004:
Michael Tsai’s SpamSieve epitomizes the idea of utility software that does one thing, and does it well. What SpamSieve does is identify spam in your email, and it does so with accuracy that approaches perfection.
SpamSieve 2.2 was released in August, ostensibly as a relatively minor feature to SpamSieve 2.x. My results with 2.2 (and continuing up through the current 2.2.4 release) have been a decided and noticeable increase in accuracy. SpamSieve went from great to really great.
- February 2005 - SpamSieve is on Surf-Bits’s Top Ten Software Picks
- January 2005 - Michael Alderete surveys anti-spam tools:
[SpamSieve] only took a training pass at my archived spam and Inbox (a few thousand messages between them), and a couple of days use proved that it was noticeably better than SpamWatch.
Its final fault gone, and with the best scoring engine and perfect integration with Eudora, it is by far the best tool I’ve used for managing the amount of spam I get, and I’m happily using it today. Compatible with virtually every e-mail client running on Mac OS X, it totally deserves its reputation as being the best anti-spam tool available on my platform of choice. Highly, highly recommended.
If you like Mail.app, since you can use SpamSieve with it, that’s what I’d recommend doing, and blow off the built-in junk mail controls.
- November 2004 - Mac Annoyances by John Rizzo recommends SpamSieve (p. 26):
The easiest, most effective Bayesian filter is SpamSieve.…Mail’s built-in filter is pretty good, but SpamSieve is more accurate and catches more spam than Apple Mail. SpamSieve is also safe—in the 11,000 messages SpamSieve has filtered for me, it has only once incorrectly identified a legitimate message as spam.

We opened a bottle of good Aussie bubbly here at The Barrow the other day to celebrate the first day in several years that we hadn’t received a single spam message in our email inbox.
We raised a glass to US software developer Michael Tsai, the man behind SpamSieve, a program that has changed our office life and promises to restore our sanity.
November 2004 - macHOME (p. 42) writes:
Mailsmith has excellent spam protection. In fact, it too can be tightly integrated with SpamSieve, just like PowerMail. We think she’d love how it would handle her junk mail easily, and with only a minimum of configuration. (“I don’t have to think about it? Great!”)

[SpamSieve] is superior in many ways to what you’ll find in Mail or Entourage.
October 2004 - Macworld (p. 75) says:
One of our favorite add-on spam filters is Michael Tsai’s $25 SpamSieve…a powerful, accurate, and highly configurable statistical filter.
August 2004 - MDJ 2004.08.30:
[SpamSieve is] the easy choice of the vast majority of current and former MDJ staffers, not only due to its tight integration with Mailsmith 2.1 and later, but also because it mostly just works—accurately identifying over 99% of spam messages that slip through to our production system, for example. There are lots of tiny shareware “spam filters” out there, but only SpamSieve won the 2003 Macworld Editor’s Choice Award, and we think there’s a reason for that.
July 2004 - TidBITS#736:
We of course hope that Postini will be equally as accurate as the client-side filters many of us already use; Michael Tsai’s SpamSieve remains about 99.6 percent effective for me…

May 2004 - The Mac Night Owl:
After about a week of use, SpamSieve settled had reached 99.2% correct identifications of spam, and accuracy continued to increase in tiny increments. Yes, there are other applications that promise to accomplish the same result, but SpamSieve is regarded as the most effective solution out there.
May 2004 - Cheryl K. Olson writes in the Wall Street Journal Online:
I am incredibly happy with a product called SpamSieve, which—once “trained” by feeding it examples of good mail and spam—has virtually no false positives or negatives.
April 2004 - My Mac reviews SpamSieve:
If you’re encountering spam problems and you’re at your wits end, I highly recommend that you check out SpamSieve if you have one of the email programs that I’ve listed above. For the price, it’s the best expenditure of money for peace of email that I can think of. My Mac Rating: 5 out of 5.
March 2004 - macCompanion reviews SpamSieve:
Now, are there competitors to SpamSieve? Good heavens, yes! Lots!! But none I’ve seen so far go as far or work as well.… I sure hope Apple auto-installs SpamSieve as an add-on to [Apple Mail] in the next release of Mac OS X.
February 2004 - Macworld names SpamSieve “Software of the Year” (p. 77).
The best way to keep these obnoxious messages at bay is the heroic Michael Tsai’s SpamSieve 2.0.…Unlike other programs, which force you to check a separate program for mismarked mail, you use SpamSieve right inside your everyday e-mail program. Forget spam about reducing body parts, and use SpamSieve to reduce something else: your spam count.
February 2004 - MacOPINION:
SpamSieve is smart. I did have a plentiful supply of good and bad emails for it to sample initially, but literally within a day it was achieving 99% accuracy.
February 2004 - MacAddict reviews Eudora 6.0.1 (p. 49).
With average accuracy in the low 90-percent range, [Eudora] SpamWatch isn’t as good as our preferred third-party spaminator, SpamSieve 2.0.
January 2004 - TidBITS notes an increase in spam volume.
Luckily, Michael Tsai’s SpamSieve is doing a swell job of identifying and extracting the spam from my Eudora mailboxes; it’s currently 99.6 percent correct in identifying spam.
January 2004 - O’Grady’s PowerPage awards SpamSieve 2.1.1 the first O’Grady PowerPick of 2004.
I was pretty happy with Mail.app's Spam filtering until I realize that it is rather stagnant, not dynamically learning about new Spam with use. As spammers get better at defeating Mail's Junk Mail rules, more wound up in my In Box.…SpamSieve is like a light at then end of the Spam tunnel. Installing and training it has reduced my Spam to zero (literally).
- January 2004 - Macworld features SpamSieve in its “Shop Smart: Software for Less” article.
January 2004 - Macworld reviews Eudora 6.0 (p. 34).
SpamSieve was a more effective spam blocker than Eudora 6’s built-in filters.
December 2003 - MacInTouch readers choose SpamSieve as a runner-up for best communication product.
It’s awesome, easy to use, catches 99.9% of my spam now with the latest version. Integrates perfectly with Entourage (which is what I use). It has so radically reduced the amount of spam I deal with, it is absolutely a necessity!

November 2003 - MDJ 2003.11.14 says:

November 2003 - MacAddict reviews Mailsmith 2.0.1.
[Mailsmith] Version 2 brings seamless integration with Apple’s Address Book app, PGP encryption, the excellent SpamSieve junk-mail detector, and SpamCop reporting.

One you train it, SpamSieve’s accuracy is fantastic. This accuracy, plus the fact that SpamSieve integrates right into your email program, makes it our preferred filter.
October 2003 - MacUser UK reviews SpamSieve 2:
If the level of spam you receive is high, then SpamSieve is an excellent option. What’s more, at $25, it’s a bargain.
September 2003 - MacCentral writes:
I get a large volume of spam, as my e-mail address is in plain sight for any Web crawler or harvesting out there—upwards of 2,000 or more pieces a day on average, not counting all the recent blowback from SoBig.f and related e-mail server bouncebacks. I’ve been using SpamSieve regularly since earlier this year and find it very, very effective.
September 2003 - Jim Dalrymple compares SpamSieve 2.0 and Apple Mail’s spam filter.
If you receive a lot of emails and are constantly fighting with spam, there is no reason to fight any longer. For a small Shareware fee you can be rid of junk email in your Inbox (mine is 99.2 percent effective) for good.

The first aspect you will appreciate about this product its comprehensiveness and professional execution. More than just a crude hack to implement an open-source offering as a Mac OS X application, SpamSieve includes some of the best documentation we have ever seen in a US $20 shareware product. Not only is there a detailed explanation of how exactly Bayesian filtering works, explanation of the already straightforward features is excellent.
April 2003 - Macworld’s cover story on anti-spam software awards SpamSieve 1.2.2 four mice, higher than all the other products reviewed (p. 64).
