The U.S.P.S. has made some changes. These days, the post office uses machines to sort mail and mark each stamp as being used. However, when it comes to mailing delicate pieces of mail, like an enormous wedding invitation with crystals, wax seals, etc., they are fragile and potentially subject to damage.
According to the United States Postal Service (U.S.P.S.), hand-canceling was no longer available in June 2019. The post office now offers to purchase a non-machinable surcharge stamp along with any additional-ounce stamps. The risk is entirely in whether the postal worker assigned to the envelopes follows the protocol for non-machinable stampsor not. If you have an elegant, embellished, or oddly shaped invitation, we recommend purchasing the optional non-machinable surcharge stamp.
You will have to weigh out the cost-benefit option for your scenario.
