Rated 5 out of 5 stars

My previous message template TB extension was good but no longer supported so I moved to SmartTemplates. SmartTemplates worked with my existing templates and it is more flexible, more sophisticated (variables). I was well supported when I had teething problems. Completely worth the small annual fee to support the development.
I am a long-standing software professional and I am easily displeased with most software because it is poorly thought out and/or badly made. SmartTemplates seems well designed and it works. I am very happy.

This review is for a previous version of the add-on (3.7).
