Q. With the holiday season approaching, I have a question. Can I mail a parcel at Parcel Post rates that has an envelope containing a greeting card attached to the front of the parcel?

A. Glad you asked. The two relevant DMM references are: E710.1.4 and E710.1.6. If the card (presumably like a holiday card in an envelope) is just a greeting card that has to do with a gift that’s in the parcel, then the whole parcel can be mailed as Parcel Post as long as there are no other First-Class Mail contents in the package itself. If the “card” on front contains a lengthy message other than a simple greeting, the card would have to be paid for at the First-Class Mail rate in addition to the Parcel Post rate and should be marked “First-Class Mail Enclosed” just under the postage.
