Rated 5 out of 5 stars

I finally got a license today.
It's about time. Thanks for your work! :-)

This review is for a previous version of the add-on (2.6). 

Thanks for supporting SmartTemplate!
People really have no idea how much work making and maintaining a good Add-on is. With your contribution, you are keeping this project alive; the more people support it, the cheaper and better it will get.

Super Add-on, together with Stationary perfect. I'll stay with free Version 2.0, but at some point I will reward all your work with the purchase of a license. Thanks, Danke.

This review is for a previous version of the add-on (2.3.1). 

thanks for the encouraging words. 2.3.1 has external templates support added so we won't miss Stationery as much once Thunderbird 68.2 will be rolled out to all users. I know how important Stationery is to myself, so I worked hard to integrate this feature into SmartTemplate⁴. The feature is also available with a Standard license (5 bucks).
