in the current version the sending of emails is very simple. You cannot add custom headers.

For the moment you could add a keyword or similar to the subject, and create a rule in your eMail client that flags an email as important if the keyword is present in the subject. If you are sending notifications to a small group of users this may be suitable and better than not having the flag set at all.
