Under the Pre-Renovation Education Rule, I have the option of using a certificate of mailing to notify the owner or occupant. What is the difference between a certificate of mailing and certified mail?

A certificate of mailing is a receipt showing evidence of mailing, while certified mail provides proof of mailing and delivery of mail. When using the certificate of mailing option, no record is kept at the mailing office and a receipt is not obtained when mail is delivered to the addressee.
