My wife has a Galaxy J5 running Marshmallow. She would like an email app, paid for if necessary, that will allow her to set a permanent "reply-to" address that is unconnected with any of the accounts on her phone. I've looked at a number of apps, but none say they can do this. Several apps will allow you to send from another account, but that is no good to her. I use K-@ Mail Pro, which has this facility, but we would prefer to find an alternative, and without having to download different apps in succession to try out (we've already tried BlueMail). Can anyone help please?
