USPS facts first, price second
This is a planning checker, not a postage purchase or route picker. EDDM Retail uses Marketing Mail flats: a 4 × 6 piece is a letter, not an eligible EDDM flat. The house default is 6.5 × 9 inches. Businesses-only delivery is not an EDDM audience; choose routes with homes or all addresses through USPS.
- Enter the finished size and the assumptions that are actually true for this job.
- Read each warning, not only the headline color. A warning is a next action.
- Confirm the exact official template, then request a proof when the detail matters.
What this tool cannot certify
No browser calculator can see every production decision. It cannot approve a complex PDF’s fonts, overprint, fold order, variable data, spelling, legal copy, official template fit or a final printed QR scan. Those checks remain part of the official guideline and proof process.

Questions customers ask before printing
Is 4 × 6 eligible for EDDM?
No. 4 × 6 is a letter. EDDM Retail flats must exceed the letter limits and stay within USPS maximum dimensions and thickness. Do not solve this by changing only the artwork pixels: the physical finished piece, stock and preparation must be eligible for the service you select.
Can I target businesses only?
No. EDDM is built for carrier routes covering homes or all addresses. For a business-only list, use a regular addressed-mail workflow with your own list and request a quote. That workflow has different addressing, postage and list requirements, so do not label it EDDM in the artwork or order notes.
Does this include postage?
No. Postage is not included in this check or in the 55printing cart. USPS rates can change; confirm current rates with USPS before mailing. Treat any calculator result as a planning scenario, and confirm the current rate, deposit preparation and route paperwork with USPS before committing a campaign.
