MailTags is a must-have for email power users. - Macworld Gem, March 21, 2006

The reason MailTags is so useful is because it does more than just tagging. The tagging, if you use it carefully and thoughtfully, will make locating and filing emails a lot easier and simpler than the old folder system (hint: define some rules to apply tags, and do it early). MailTags also offers iCal integration, project management, and more, which is what makes it really stand out as a must-have app. This is perhaps a useful object lesson: you can do a lot of cool stuff with tags, but the best tagging software will implement tagging into a larger picture. - Tagamac.com - Aug 21, 2007
