Just in case you weren't aware, the USPS is running a direct mail promotion throughout the months of July and August. I have a 32-page document that details the promotion, but here's what actually matters to you.
If you use a QR code on a direct mail piece, letter or flat, during the months of July and August, the USPS will give you a 3% discount on your postage.
This discount would apply to permit-imprinted letters or flats, mailing First Class, Standard or Non-Profit.
To qualify for the discount, you must display the QR code either outside or within all mailpieces in a mailing.
Do that, and you'll earn your 3% discount.
If you've never generated a QR code before, you need not worry. It is SUPER easy. I generally use http://quikqr.com/.
If you have any questions about QR codes or this USPS promotion, feel free to drop us a line.
