Choose the right size box.  Don’t mail anything that isn’t a piece of paper in a regular envelope. Greeting cards are fine, but if you’re trying to include something lumpy, like jewelry, flash drives, etc., the envelope can break open and the contents fall out.  In fact, even gift cards shouldn’t be mailed in a plain envelope as the postal system’s automated sorting equipment can destroy them.  Pay the extra non-machinable charge to avoid the sorting machine.

Use a new box for shipping. Used boxes don’t hold up as well during shipping. Also, make sure to fill the box completely with packing peanuts.  If you leave empty spaces, the box flaps can cave in, resulting the package opening during transit.

Use professional-grade packaging tape. Duct tape, masking tape, painter’s tape, and cellophane tape don’t hold a strong enough seal in the shipping environment, especially in colder weather. If you use something other than packing tape to seal your package, you run the risk of the box opening and the contents falling out.

Place a copy of the delivery information inside the package. Sometimes, the box doesn’t hold up to the shipping process (especially if you reuse an old shipping carton – which you shouldn’t).  If the delivery label is lost, the carrier will still be able to deliver your package.
