How can I create an email, that has contact information (banner) on the top of the email?

[iMore Question]

Occasionally, I get an email that when I open it in Mail on my iPhone (iOS8), that person's contact information is in a banner at the top of the email. I can either 'Ignore' or 'Add to Contacts'. I would like to be able to do this on the emails I send out - how do I do this? - Michael Stern

You can't... It's an iOS feature that offers that when detected in an email that's a reply to something you've sent... So if someone with an iOS device sends you mail, and you reply... The person that sent you the message should get the option to add you to their contacts if you're not already in their contacts. You don't have to do anything.
