I am an Acymailing user since 2009.
The features are always outstanding and more flexible than all other tools I know.
And you can create own modules and connections.
One downside is not yet compatible with Zapier
I love Freescout, Use it for multiple clients.
One downside is that the app is just the website on your phone and does not really work well.
It works but not as an App experience.
For the rest they do awesome and developing in it works good!
