EDDM Routes in 45237 — Cincinnati, OH

What EDDM costs

Postage rates verified August 2026. USPS raised EDDM Retail on 12 July 2026 — guides published before that date still quote the older figure. USPS Notice 123 is authoritative.

How EDDM works

1. Choose carrier routes. You buy whole routes, not addresses. Every door on a selected route gets a piece.
2. Print to flat dimensions. The piece must exceed 6.125 × 11.5 inches or be over 0.25 inches thick, and weigh under 3.3 ounces. A standard postcard is too small to qualify.
3. Address it "POSTAL CUSTOMER". No names, no street addresses — that is the whole point of the programme.
4. Bundle in 50s or 100s with a facing slip on each bundle.
5. File PS Form 3587, one per ZIP code.
6. Drop at the facility serving those routes and pay at the counter. A plan spanning several facilities means several trips.

Where mailers lose money

• Buying by radius instead of by budget. A three-mile circle can be 14,000 doors — nearly $3,700 in postage alone. Set the budget first and let the tool pick the routes that fit.
• Ignoring the drop-off count. Routes near a boundary often belong to different facilities. Four facilities is four trips, and that cost never shows up in a per-piece estimate.
• Missing the 200-piece minimum. A ZIP with only a sliver of coverage cannot be mailed at all. The planner drops those automatically and tells you.
• Printing before confirming counts. Delivery statistics lag reality. Confirm at the counter, then print.
• Assuming saturation equals response. EDDM is the cheapest way to reach everyone, which is different from the cheapest way to reach a customer. For a narrow target, addressed mail to a filtered list often costs less per response despite higher postage.
