What is EDDM?

eedm size requirements for postcards Every Door Direct Mail (EDDM) is a retail solution offered to businesses by the USPS. This service allows you to choose the neighborhood you want to target, and the postal service will deliver your mail to your exact specifications.

Importantly, EDDM enables businesses to send up to 5,000 mailpieces per day through Standard Mail delivery. Therefore, you don’t need to purchase postage permits, and no names or addresses are required. This allows you to reach more people for a fraction of what non-EDDM postal costs would be.

EDDM Retail Size Specifications

The size and weight of your mailpiece play crucial roles in determining the mail class and associated postage rates. For postcards sent through EDDM, the USPS has specific size requirements:

  • Minimum Size: One side must be longer than 6 1/8 inches high or 10.5 inches long.
  • Maximum Size: No side should exceed 15 inches in length or 12 inches in height.
  • Weight Limit: Each postcard should not weigh more than 3.3 ounces.
  • Thickness: Postcards must be thicker than 0.007 inches but not exceed 0.75 inches.

The USPS is strict about these specifications. Any mail that doesn’t meet these specifications will not qualify for EDDM rates. When you work with Epsilon Individual Automotive, we’ll ensure every piece of mail sent out is compliant with EDDM’s specifications.
