how to tell hotmail email was read that was sent from iohone

I don't believe Hotmail offers that service, but if they did, it would have to enabled by the recipient to "Send read receipt"

Other than asking that person, there is no way to tell.

There is no way to determine that. Even in a system that sends "read receipts", it simply means the email was accessed. It is not possible in any system for you be certain someone has read an email.
