I'm a Things user and I want my MailMe Text e-mails to show up as tasks in Things. So, this is how I've made my every day a bit more efficient. :-)
1. Download the Things AppleScript and save it in a folder on your harddrive.
2. Go into the settings in MailMe Text and set a mail subject prefix. Make it unique so you can make a mail rule for MailMe Text.
3. Apply a rule in Apple Mail by going into the rules menu in preferences. Add a new rule. Set the filter to "Subject" and "Begins with" and add your MailMe prefix. Then select what action to perform. In this case the action is to "Run AppleScript". Select the AppleScript that you downloaded before. Finish by adding the delete mail action. This is important so that you don't import the same mail more than once.
Now when you start Apple Mail on your computer it will automatically import your MailMe Text todos to your Things inbox.
Do you have any cool tips for MailMe integration with Things or other to-do apps?
