Key Benefits of Every Door Direct Mail (EDDM)

Every Door Direct Mail (EDDM) is an official United States Postal Service program designed to help local businesses reach every household along specific mail carrier routes. Unlike traditional direct mail campaigns that require buying expensive customer databases, EDDM allows you to target entire zip codes at a fraction of standard First-Class rates:

• Reduced Postage Rates: Enjoy significantly lower per-piece postage fees compared to standard marketing mail or First-Class postcards when distributing in bulk.
• No Mailing List Required: Skip database licensing costs entirely by using official USPS carrier route mapping tools to target specific residential or business neighborhoods.
• High Impact Visual Real Estate: Because EDDM requires larger “flat” dimensions, your promotional cards stand out prominently in customer mailboxes compared to standard envelopes.
• Simplified Mail Preparation: Eliminate individual recipient name and address printing (variable data printing), reducing pre-press production times.

Understanding USPS EDDM Dimensional & Weight Rules

To qualify for discounted EDDM Retail rates, your printed artwork must strictly adhere to official USPS flat-sized mailpiece standards. If a postcard falls outside these parameters, USPS processing equipment will reclassify it as standard mail, resulting in unexpected postage rate hikes:

1. Minimum Sizing Standards: A qualifying EDDM mailpiece must measure greater than 10.5 inches in length OR greater than 6.125 inches in height. Popular compliant dimensions include 6.25″ x 11″, 8.5″ x 11″, and 6″ x 12″.
2. Maximum Dimension Limits: No single side of the piece can exceed 15 inches in length or 12 inches in height.
3. Thickness Requirements: Mailpieces must have a uniform thickness of at least 0.007 inches (roughly 7pt cardstock) and cannot exceed 0.25 inches thick. We recommend heavy-duty stocks like 14pt Gloss Cover or 16pt Premium Matte for durability.
4. Weight Thresholds: Individual EDDM Retail pieces must weigh no more than 3.3 ounces (93.5 grams).

How to Plan an Effective Direct Mail Campaign: Step-by-Step

To execute a flawless direct mail run, start by defining your primary objective—such as promoting a grand opening, offering seasonal coupons, or highlighting local service areas. Next, select your target carrier routes using demographic filters like median household income or residential density. Once your route quantities are locked in, prepare artwork using high-contrast typography, clear call-to-actions, and required USPS postal indicia artwork zones.
