The recent update said there is now support for dynamic text and referred to support page but there’s nothing on the support page about it.
This app saves me time, allowing me to send group emails from my iPad no matter where I am. It is simple and quick to set up and use immediately. Now I don't have to be at home with my tower computer to send groups mails. There is a detailed manual to access from the app itself with a tutorial. If the manual does not have your answer, the app also has a means of contacting the creator by email. He replies quickly with a diagnosis and solution. This app is outstanding and very reasonably priced.
