Mailsmith is a Internet email client for Mac OS X which offers unparalleled filtering, searching, editing and scripting capabilities. In addition to the strides made in these areas, Mailsmith breaks new ground in making powerful email-handling capabilities accessible to users of all levels. Key features include:
  • Compatibility: Standards-based
  • Multi-threaded processing
  • Distributed Filters
  • Approximate ("fuzzy") searching
  • Advanced Querying for Mail: including options for using 'grep' pattern matching
  • Powerful OSA scripting:
  • Advanced text composition more...

What's New

Version 2.3.1:
  • Fixed bug in which space-bar navigation didn't work correctly.
  • Fixed memory leaks discovered during rebuild/migration testing.
  • Mailsmith no longer checks the installed version of SpamSieve; this avoids problems in which the version number in newer versions incorrectly failed the requirements test, so that Mailsmith thought that SpamSieve was not available.


Mac OS X 10.5 or later

What used to be the most expensive e-mail client available, is now the cheapest (free, even). And, for someone like me who's always wanted to become a Mailsmith user but found myself in the wrong tax bracket, this is very good news.

I can put what's attractive about Mailsmith very succinctly, as it gives you most the text editing powers of BBEdit (which are many) in an e-mail client. If that sentence means nothing to you, then you probably won't care about Mailsmith. Like BBEdit, it's spartan and utilitarian. But like me and the thousands of other BBEdit users, we only care about what's under the hood.

Now with that said, there's a few things that bug me about the program. The inability to reorganize the mailbox list or toolbar is a little bothersome, and I wouldn't call it's functionality exactly intuitive. But then again, having multiple clipboards and hot-keyed clippings more than make up for it, so I'll chose not to sweat the small stuff.

Also in interest of full disclosure, I feel I should mention it's spam filtering capabilities are limited. This is a feature not terribly important to me, but others seem to live and die by it. They do include a demo of SpamSieve as a consolation (which I find more annoying than spam itself. Luckily, being an old Powermail user, I've learned to turn that thing off in a quick hurry). But I've found the in-program filtering to be sufficient.

Anyway, if you've read this far, you should at least give it a try. Like BBEdit, there's a bit of a learning curve. But there's numerous rewards for riding that curve out. If you're serious about your e-mail composition, this program is as serious as you.

I really love MailSmith and hope that it stay what it is: A tool for the pros. There are enough tool/apps with blinking elements and funny popups but without all the features needed by the pros.
Mailsmith is the ONLY mail program I know (and I have tested a lot if not all for Mac) that can handle my 420 SMTP accounts combined with just 1 POP3 account. It can pass all my mails through my own scripts using the shell. It's one of really few clients that displays raw content without all these stupid HTML-Elements. If you request HTML you also want to have a build security hole. I don't want my mail in HTML.
And Mailsmith is really fast. I have over 5000 mails in my archives and can search in < 30sec in all these mails for any term.

Summed up: Mailsmith is for the pros. If you search an 'app' don't use this as this program provides features not fun. Without some knowledge in POP3,SMTP,Shell,RegEx.. you possibly even don't know what to do with all these features.

Bought this years ago for a lot of money and although it's free now I don't regret that I payed for it.

The BIG disqualifier for me years ago was no IMAP support. Seems the final version also doesn't do IMAP. Oh well. Eudora and now Mailsmith. Pity.

This kind of user-interface (whereever that is!) makes me angry.
Sluggish, impossible to find the functionality you're looking for (eg. setting up accounts), etc. Everything is malplaced and slow.
Won't recommend.

No need to hold breath. Hey presto...

A new public release of Mailsmith is now available; version
2.3.1 includes a couple of bug fixes.


"impossible to find the functionality you're looking for (eg. setting up accounts)"

As they say, Read The Friendly Manual ;)
It took me a few seconds to find the instructions in page 14.
I have not read that section, but I got "lucky" and found this functionality under Window>Accounts.
Many years ago I did read parts of the manual regarding searching, filtering, scripting, etc.

You could also try the Help. It clearly shows how to set up your accounts.

There is fortunately a wide variety of email clients for everyone needs and preferences. I've been a Mailsmith user for some time now and I feel very happy with it; it's very powerful when it comes to filtering and text editing. I noticed a great difference when I had to deal with thousand of e-mails.

I recently have switched, especially due to its high speed search capabilities, to PowerMail, but Mailsmith is still a great piece of software.

There are excellent email clients, not so sophisticated as Mailsmith and PowerMail, but which do the work.

It's a matter of being confortable with the tools you chose. If Mailsmith does not suit your needs, it's ok for you to find other alternatives. I also like GyazMail.

It is my understanding that this email client will Not do IMAP. Is this true? Obviously this would be a disadvantage to people that use imap (this should be everyone btw).

This kind of made me giggle: not doing IMAP is a disadvantage to people who use IMAP. Well, yeah...

Seriously, though, if Mailsmith was your favorite email app (and it was for me), you should take a look at MailMate. It's IMAP-only, and very powerful, stable, and actively developed.


@wilcox, ya that is worded oddly, I seem to be good at that. Seriously though, I have IMAP and POP3 accounts for my email so I need an email client that does both obviously.

Sherman Wilcox

@Lee123 at this point then MailMate won't work for you, because it's IMAP only. Too bad, because it's good stuff.


Whenever I used IMAP, I always found it cumbersome and awkward.
I've used POP for 12 years now, and am using it on my own mail servers; I still find POP the best (for me), so I don't need IMAP.

Mailsmith has gotten better, not the least because it's now free. But it still has some quirks that bother me. To begin with, it will display an HTML message only as an attachment, which means extra clicks and windows to deal with. Also, mail message window size is inconsistent and after considerable experimentation in the preferences I could find no way to standardize it.

Among the application's strengths is support for SpamSeive, a robust spam filter. Other than window width, the interface is quite flexible, though there appears to be no way to customize the menu bar.

It is another program, like Text Wrangler, that BareBones has set free, for which I commend them. It remains to be seen if the "new" company in charge of it will continue development.

After reading all of your comments ProgramHappy I think you should consider changing your nic to ProgramUnhappy.

Drop dead.


Thank you for making my point for me.

Sherman Wilcox

I think the correct name for ProgramHappy is jack*ss. His reply to your post proves that.


Hey MU staff, since when are personal attacks acceptable here?

Great application. And fast too...
But, please, add IMAP support...

I was on mailsmith-talk for many years. The subject of IMAP support came up once every few weeks. It became pretty clear that Bare Bones would absolutely never, ever, ever, ever, ever integrate IMAP support into the application. It's under new management, but the new management is the former head of BBSW.

I think it's a very safe assumption that you're never going to see Mailsmith support IMAP.

...did I miss something, or am I unable to change the font style for individual words. Whenever I tried to bold a word, the entire message was bolded.

Also, I wasn't able to paste images inline.

Both of those issues are dealbreakers for me, even though the software is free.

Sorry to disappoint, but mailsmith is plain text only. You can attach images, but not add them inline, and styling of text on a per-word basis would require html, which mailsmith doesn't do.


Thank you for replying. It is a nice app, so I'll have to think about whether I can get by without those two features.
