9 EDDM Mistakes That Get Your Mailing Rejected (and How to Avoid Them)

Morgan Reed · May 29, 2026

The nine specific things that derail EDDM campaigns at the post office counter, from indicia layout to bundle counts, with the fix for each.

This is for anyone about to drop an EDDM (Every Door Direct Mail) job at the post office, or anyone who just had one handed back. By the end you will know the nine mistakes that cause the most delays and how to fix each one before you load the car. Start with our EDDM size guidelines if you have not picked a size yet.

Quick answer: the 9 most common EDDM mistakes

Almost every rejected EDDM mailing fails for one of nine reasons. Here is the list, the symptom, and the fix.

MistakeSymptomFix
1. Size does not qualify as a flatClerk says "this is a postcard, not a flat"Use 6.5x9, 6.5x11, 8.5x11, 9x12, or 11x17 folded
2. Stamp box or address line on designConfused clerk, design reworkRemove both — EDDM uses indicia and "Local Postal Customer"
3. Wrong or missing indicia textMailing refused at counterUse the exact EDDM Retail indicia block, upper right of mailing panel
4. Bleed or safe zone errorsLogos or offers trimmed off0.125" bleed all sides, keep critical text 0.25" inside trim
5. Bundles not 50–100 piecesBundle handed back, "resort and come back"Re-bundle so every stack is between 50 and 100
6. Missing or wrong facing slipsClerk cannot match bundle to routeOne facing slip per bundle, route ID and piece count filled in
7. Dropped at wrong post officeCounter staff turns you awayDrop at the destination PO that serves the selected routes
8. Too many routes for the budgetOne mailing, no response, no budget for a secondFewer routes, mail them 2–3 times instead
9. No test before a big print run25,000 pieces of a design that does not workPrint 2,500–5,000 first, learn, then scale

Rule of thumb: The two mistakes that delay mailings most often are (1) wrong indicia layout and (2) bundles that aren't exactly 50–100 pieces. Get those right and the rest is straightforward.

Mistake 1: Picking a size that doesn't qualify (4×6, 5×7, standard 6×9)

EDDM Retail requires a flat, not a standard postcard. A piece qualifies as a flat only if it exceeds at least one of three thresholds: longer than 11.5", taller than 6.125", or thicker than 0.25". A 4×6 misses all three. A 5×7 misses all three. A standard 6×9 is the most common heartbreak — 9" is under 11.5" and 6" is under 6.125", so most printers will not accept it for EDDM.

The five sizes that qualify cleanly are 6.5×9, 6.5×11, 8.5×11, 9×12, and 11×17 folded. If a designer hands you a 6×9 file, extend it to 6.5×9 before print. See EDDM size requirements for the exact rules.

Mistake 2: Designing with a stamp box or individual address line

EDDM does not use stamps and does not use individual addresses. A traditional postcard template has a stamp box in the upper right and a recipient address block on the back. Both have to go. The upper right is reserved for the indicia (the block of printed text that replaces the stamp), and the address line is replaced by "Local Postal Customer" or left blank.

If you reuse a template from a targeted mailing, this is the most common rework. Strip the stamp box and the address block before sending to print. Our indicia and mailing panel guide shows what the back should look like.

Mistake 3: Wrong indicia text or no indicia at all

The indicia is the small block of text in the upper right corner of the mailing panel that tells USPS this is paid EDDM Retail mail. If it is missing, the clerk will not accept the mailing. If it is the wrong indicia (a permit imprint from a different mailing class), same result.

Use the exact EDDM Retail indicia block. Most print shops drop it on for you when you flag the job as EDDM. If you are designing your own file, copy it letter-for-letter from the indicia reference page and do not retype it from memory.

Mistake 4: Bleed and safe zone errors that get artwork clipped

Print files need a 0.125" bleed on every side and a 0.25" safe zone inside the trim line for critical text. Commercial trimming can drift up to 0.0625" in either direction. If your phone number sits right at the edge, half of it ends up on the cutting room floor.

The fix is mechanical. Add bleed in your design tool's export settings, and pull any phone number, QR code, or offer text 0.25" inside the trim. A QR code clipped on one corner will not scan. A phone number missing its last digit will not ring.

Mistake 5: Bundles that aren't 50–100 pieces

USPS requires EDDM Retail bundles to contain between 50 and 100 mailpieces. Anything outside that range is rejected at the counter. A 240-piece route is three bundles (100 + 100 + 40), not one big stack.

The math is simple but easy to fumble when you are bundling four routes on the kitchen table at 9pm. Count twice, band once. Full instructions are on the bundling and facing slips page.

Mistake 6: Forgetting facing slips or filling them out wrong

A facing slip is a single printed page that sits on top of each bundle. It tells the clerk which carrier route the bundle belongs to, how many pieces are inside, and who the mailer is. Every bundle needs one.

The two common errors are leaving the piece count blank and listing the wrong route ID. If the slip says route C014 and your selected route was C041, the bundle goes back in the trunk. Print the slips from the USPS template and double-check route IDs against your route list.

Mistake 7: Dropping at the wrong post office

EDDM Retail mail has to be dropped at the destination post office that serves the selected routes, not the one nearest to you. If your routes are in the 77024 ZIP, the mail goes to the 77024 post office, even if your business is in 77019. The wrong building cannot accept it — they have no way to get the bundles onto the right carriers' shelves.

Confirm the destination address before you load the car. Your route list will tell you the ZIP. If you selected routes across two ZIP codes, that is two separate drops.

Mistake 8: Choosing too many routes for the budget (over-reach instead of frequency)

The most expensive mistake on this list is also the most common. A first-time mailer picks 12 routes and 15,000 pieces to "cover the whole area." The campaign goes out once, gets a soft response, and there is no budget left for a second mailing. Direct mail almost always performs better on the second and third touch.

Fewer routes mailed more than once. Two routes and 2,000 pieces, mailed three times over six weeks, will usually outperform 12 routes mailed once.

Mistake 9: Not testing — mailing 25,000 pieces of an untested design

Print 2,500 to 5,000 of a new design before you scale. Designs that look great on screen sometimes fall flat in a mailbox, and a small first run gives you a real response rate. Once you know a piece pulls, the math for a larger second run is straightforward.

The mistake usually shows up with small business owners mailing for the first time who want to go big. The conservative version — smaller test, then scale — costs less and produces more usable data.

Frequently asked questions

What happens if the post office rejects my mailing?

The clerk hands it back and tells you what to fix. Most rejections are bundle size, indicia, or facing slip errors, all fixable on the spot or with a return trip. The mail itself is not destroyed; it just does not enter the mailstream until the prep is correct.

Can I fix bundle sizes at the post office counter?

Sometimes, if the clerk is patient and there is no line behind you. Bundle correctly before you leave. Bring extra rubber bands and a few blank facing slips just in case.

Does EDDM2GO handle all this for me?

Yes. Full-service EDDM means we print, bundle by route, attach facing slips, complete the USPS paperwork, and drop the mailing at the destination post office. You approve a proof and the rest is on us. See the EDDM quote page for current pricing.

How long does it take to fix a rejected mailing?

Bundles or facing slips, usually an hour. A bad printed indicia or a non-qualifying size means a reprint, which adds production time. That is why the prep work matters before anything goes to press.
