A really useful, time-saving filing tool

In Situ

This app lets you quickly file emails in mailboxes with keyboard shortcuts. I have a large hierarchy of mailboxes in 7 email accounts (Gmail and generic IMAP) so for me, is a huge time saver. I’ve used it to file 374 messages in just the last few days.

It also does other things like let you open mailboxes with shortcuts, and create new mailboxes on the fly. Nice added bonuses. The developer is also very responsive and friendly.

While I’m giving it a 5-star rating I hope the developer fixes two bugs: (1) the “recents” feature doesn’t work when restricting mailboxes to the current account. Still, in actual use, I don’t notice that not working so much. (2) The other bug is more annooying - an error message that pops up when creating a nested mailbox. That one I really hope he fixes!

Basically finding and filing in mailboxes works very well, and is extremely fast.

I had been a Mail Act-On user, but it stopped working with Yosemite for the case where you have a Japanese keyboard installed. I love indev too. They are really nice and responsive. But they indicated they cannot fix that bug and refunded my money. If you are not using foreign language keyboards their software is also great. More expensive, but very nice.

However, I had been using Mail Act-On just for the filing shortcuts and it was no longer working. MsgFiler has no problems in finding English and Japanese mailboxes.

One note: Some people might think $10 is a high price for an app which “just files.” That was my original reaction too, and I was hesitant about trying it. But I contacted the developer, asked a few questions, he responded quickly and pointed me to a deprecated plugin version I could test with first. I was hooked and purchased right away. If you haven’t tried filing mails with a couple of keystrokes you probably don’t yet appreciate how much of a time-saver this is over drag-and-drop, or going through the hierarchical menu (as we must in iOS), or even using the clumsy CMD+Shift+? keyboard shortcut for moving mails.

If you have a large hierarchy of mailboxes, and multiple email accounts, this is definitely a huge timesaver.

So for heavy Mail users I would say it is worth it. And I hope the developer updates it soon with those couple of needed fixes.

A promise of things to come


As the documentation on their web page tells you (when all else fails, RTFM). The new version is an application; the previous version was a Mail plug-in. What's the difference, you ask. Well, with the application, it has to be running to work. That means if you don't have it launch at system startup, you'll have to launch it. When it launches, it scans your existing mailboxes. I have a lot of mailboxes, so that initial scan takes time.

With the plug-in, it's available when you launch Mail. The developer explains that the plug-in would often break with software updates. The application apparently won't, so I understand why they did what they did. However, until my current plug-in is broken, I'll continue to use it. It's much faster. Most of the new bells and whistles of the application version (create new mailboxes, favorite mailboxes, exclude mail boxes and so forth) have no real value to me.

I've purchased the App at a reasonable introduction price of $4.99. So, assuming the plug-in won't break for a while, I've lost the use of my money in the name of saving money in the future. Even though I won't be using the APP, I'm still giving it 5 stars. For what MsgFiler has been and will be. Also for the excellent and timely support. Let me repeat that, for the excellent and timely support. I don't like the APP as much as I like the plug-in, but in either form, MsgFiler is a terrific productivity enhancer.

Best Way to Spend a Few Dollars on Software in Existence


MsgFiler transformed my experience of email. I have long used the plug-in version and am pleased to see the app come along. I receive several hundred emails a day. Most of those I auto-file with rules, but that still leaves about 100 a day to file by hand. Dragging and dropping took me forever. MsgFiler enables me to sort messages into the 622 mailboxes I have in Apple Mail in a snap. I cannot think of a single piece of software I have purchased for less than $10 that is remotely as useful to me as is MsgFiler. It literally saves me a few days of effort each year, not to mention a serious case of repetitive stress injury. The idea behind this is good enough that you really wonder why Apple didn't make its functionality part of the core of the OS. Of course, the answer is simple: like most brilliant insights, it is only obvious after the one who first comes up with it shares it with you.
