USPS
Due to the specific nature of the product, we recommend mailing your invitations in person at the post office with special requests for hand cancellation and non-machinable mail, or mailing your invitations as flats or parcels, depending on their size and overall weight of the product and in consultation with your local post office.
Hand-cancelling is when each stamp on your envelope is marked (or "cancelled") using a hand stamp instead of by a machine. Hand-cancelling cards prevents stuffed envelopes from being torn or plexiglass broken by the post office's machine.
Paying the surcharge for non-machinable letters, or sending the letters as parcels, may ensure that the invitations are hand sorted, rather than machine sorted, at different distribution centers. These processes prevent cards and envelopes that might not be machine readable ( due to their shape, size, material, ink, or color ) from being torn or broken by the post office's cancelling and sorting machines.
Envelopes included with our cards are suggested as inner envelopes in addition to padded or structured envelopes to ship via postal services.
PLEASE NOTE: We are not responsible for postal/shipping choice you make.
