Mail Act-On for Mac

With Mail Act-On for Mac you can map customized email rules more easily, creating sophisticated email workflows that ditch the repetitive and tedious process of manual email organization. This app enhances Apple's Mail app.


Easy rule creation: What makes Mail Act-On really great is the way it shortens the process of using rules in Mail. Through a pop-up menu or by pressing a key or combination of keys, you can put rules to work and, since the pop-up menu has a search field that performs the search as you type, finding lengthy rules and using them turns out to be fairly easy.

Templates for quick replies: The Edit Mail Act-On Template window presents fields through which you can set the description, the applicable Act-On key, and tokens. What's more, through the Composer options box you can set how messages will be delivered, as well as configure the archiving of sent messages.

Easy-to-understand main panel for preferences: There are three rules tabs: Inbox Rules, Outbox Rules, and Act-On Rules. The Act-On Rules tab is where you will be setting up your custom keystrokes.


Only works with Mac OS X 10.8 and 10.9: With more than a third of Mac computers at present still using versions of the Mac OS older than 10.8, it would have been great if this update of Mail Act-On (version 3.0.2) were compatible with older Macs.

Feels like renting: The price of Mail-Act On is off-putting as upgrading to the typical annual updated version costs $14.95, which is not that discounted compared to the regular $24.95 price.

Bottom Line

Mail Act-On does a great job complementing the functions of Mail. It's a handy add-on to have if you frequently need to send and receive emails, serving as a keyboard-based interface for setting and triggering Mail rules that can boost your email handling efficiency.

Editors' note: This is a review of the trial version of Mail Act-On for Mac 3.0.7.

Developer's Description

Mail Act-On is a plugin Apple's Mail (Panther & Tiger) in that allows you to map specific mail rules or actions to "Act-On" keys. When viewing mail you can apply an "Act-On" action for a message by making simple keystrokes. Mail Act-On makes use of Mail's existing rule engine, so if you have ever created a rules, you already know 99% of what you need to know to build an Act-On action. Imagine, no AppleScripts or other macros. (Even if you haven't ever created a mail rule, there is very little to learn!)
