Good tool & support

Hi,
After a year of searching (testing and subscribing to services) in order to replace the “mailman” product, which we gave in my case, some problems, I found this plugin, which solves what I need (enterprise edition).
Doubts and possible questions about how to approach the service have been resolved quickly via email: fast, effective and efficient support.
I encourage the developer to continue with his style of support that has sometimes gone beyond what he expected and to grow the project, which will surely be to the satisfaction of its customers.
