Every Door Direct Mail (EDDM) allows businesses to send marketing materials through the USPS to every home in a targeted area without address labels. It is well-suited for local businesses like restaurants, realtors, and salons seeking new customers. While design and printing services are available, EDDM mailings must be flat and within size/weight guidelines. Postage costs are much lower than traditional mail through discounted EDDM rates starting at 14.5 cents per piece.
