Great piece of software that does exactly what I need it to do. Plenty of options for tweaking the signatures to mirror my branding. Support is great, and answered all questions I had when initially setting up the software. The team is continually making improvements, and listening to suggestions. For example, they just recently released the integration with Microsoft, which is really helpful!

My only suggestion right now, is that their team develop a set of videos that walk you through the setup and creation process. That would be incredibly helpful.
