How many inserts can I include with my letter?
Our mailing equipment can include up to four inserts with your letter. We can include more than that by hand.
If you have rigid inserts (e.g. pens or CDs) or if your mailing weighs more than an ounce, extra postage will be required.
Four sheets of our 24lb regular-weight paper in an envelope with a stamp weighs exactly one ounce.
The majority of end-of-year appeals consist of one or two sheets of paper, a response slip or card, and a reply envelope. If your mailing follows this format, you won't need to worry about extra postage.
As a rule of thumb, a reply envelope weighs roughly the same as a sheet of paper, and a heavyweight sheet of paper weighs roughly twice as much.
Photo magnets weigh nearly half an ounce, so a letter that has a magnet, response slip, and reply envelope will almost definitely be over an ounce. You might consider saving the photo magnet for your Christmas card if so.
Extra postage costs $0.22/ounce, plus an extra $0.10 for hand stamping.
