Universal Email app with read receipts

[Super20]

Are there any iOS email apps that do read receipts? I know there is an app called MailTracker that installs a profile on your device, but I'm looking for an "all-in-one" solution.

There is not an all in one solution.

I believe Polymail allows read receipts.

Cloud magic aka Newton provides that feature. They became a subscription based app now though, but check it out
