Mail tracker add-in
I have this app that works with iPhone's native mail app would be awesome if it would work as an add in to outlook, it's called MAILTRACKER.

There are several mail tracking capabilities where an invisible 1x1 pixel image is loaded and lets the sender know when you have opened their email. There needs to be an option to not load remote content such as images without explicit permission. This will prevent email tracking.

Would be good if you knew if your mail has been received

It would be good if this (Outlook) support third party add in integrations. That makes life easy!!
