I have an iPad with iOS7. This is set up with 2 email accounts (gmail and ISP default). I want to use the "Contact Us" option on one of my apps, but this offers me the options of using either of the mail logon email addresses. I NEVER use either of these, and don't disclose these to anyone (so I can easily change when they get too much spam).
My question is how do I get the iPad to use the email aliases I have set up on gmail.
