I'm looking for the easiest way to set up my iPhone so that I get notified of a single person's emails immediately. My boyfriend is in the Navy & just reported to his first duty station. I know when he's underway, our best bet for contact is going to be emailing. I'd like to be notified of when he emails right away. I don't want to set up my iPhone to push emails or fetch them every 15 minutes because I don't want to be notified of when I get any email, just an email from him. Also, I know this kills battery life. I'm sure there are apps out there, but I don't know of any. And if possible, I'd like to achieve this without having to pay for an app (although it's no big deal if I have to). And if it matters, the account I'd be receiving the emails at is a gmail account.
