Summary of Features and Benefits
Emails marked as a Registered Email™ message are designed to stand out in the recipient’s mailbox and to show the recipient that the sender is treating the email with high importance. The markings include the word ‘Registered’ at the beginning of the subject line and a banner in the email body. The banner has the text ‘Registered Email Certified Delivery.’
Unmarked emails provide the sender with the same registered receipt email protection, but with the Unmarked feature, the recipient receives a standard looking email with no email markings.
