[AC Question]

I found my own answer and want to share it. To stop this on the Galaxy Note 7 do the following:

Settings
Applications
Scroll down to "Email"
Open "Email" and scroll down to "Permissions"
Open "Permissions" and deselect "SMS"

If you have this phone and it is doing something that you don't want it to, its probably being given "permission" to by an app.

This really is the best kind of answer.
