Guide Review - MailTags 3.1 - Mac OS X Mail Productivity Add-On
Usually, but not always. Something is missing from email organization in OS X Mail, and it is precisely nothing to be found anywhere in the messages as you receive them.
Adding tags and keywords is not the ideal solution to information organization, but for organizing emails (temporarily), it does wonders. With MailTags, you can assign a project, a priority and free-form keywords to each message easily, complemented by a due date and a free-form field. In Mail 3 and later, all these can be attached to RSS news feed items and notes, too. If you use Things or OmniFocus to manage your projects, their titles can show up in MailTags automatically.
At this point, Mail's own talents come into play again: using search, filters and, most of all, smart mailboxes, you can organize your emails just the way you want them effortlessly. Create a folder containing all messages about a certain project due today. Set up a filter that, for now, makes all incoming mail due next month. Make a smart mailbox showing all high priority mail.
With the Mail Act-On plug-in, you can even create keyboard shortcuts that postpone the due date or assign a project to a message to help you actually use the newly gained meta-data power.
Automatically created and maintained Calendar events and to-do items in Reminders help you remember. Message's due dates, alongside other MailTags data, can be displayed in Mail's message list. You can even have MailTags color messages as their deadline passes, for example, or employ a dainty color regime picked from the emails' priorities, projects and manually set colors.
While MailTags does work with all account types available in Mail, it may have a slight impact on performance with IMAP accounts. MailTags does keep its data on the server, though, so you can use it from multiple locations.
