If you've ever gotten a Valpak envelope or a Money Mailer in Greenville, you've experienced one form of direct mail advertising. EDDM — Every Door Direct Mail — is a different one, and for most local businesses in 75402 it's a meaningfully better fit. Here's how it works, what it costs, and the four reasons a shared 8.5×11 EDDM postcard usually outperforms the Valpak envelope for businesses your size.
What EDDM is, in one paragraph
Every Door Direct Mail is a USPS program designed for local businesses to mail to entire neighborhoods without buying or managing a mailing list. You pick the carrier routes you want to cover, the postal carrier puts your piece in every active residential mailbox on those routes, and you pay a flat per-piece rate (currently $0.213 per piece for standard EDDM Retail). No addresses, no list rental, no opt-outs to manage, no waste.
How EDDM works in ZIP 75402 specifically
Greenville's 75402 ZIP is divided by USPS into about a dozen carrier routes. Each route is one mail carrier's daily walking territory — usually somewhere between 350 and 700 active residential addresses, plus some businesses. We mail to the seven densest, highest-income residential routes: approximately 5,000 homes total.
These seven routes were chosen on purpose. They cover the older residential grid downtown plus the newer subdivisions that have the highest household-income concentration in Hunt County (around $89K average, compared to roughly $59K county-wide). If you're selling a $400 service, those are the homes most likely to actually write the check.
On any given drop, the postal carrier walks the route once and drops your piece into every active mailbox at the same time as the day's regular mail. There's no separate delivery day, no "junk mail" bundle, and no envelope to throw away first. The card ends up in the recipient's hand the moment they pick up their bills.
What the size limits mean for you
EDDM has a specific size requirement: pieces have to be larger than a standard letter so they don't get processed by automated mail equipment. The smallest legal EDDM Flat size is 6.125″ × 11″, and EDDM allows pieces up to 9″ × 12″.
We mail an 8.5″ × 11″ card. Comfortably above EDDM's minimum, too big to fit inside a Valpak envelope, and just shy of the maximum so the format feels premium without crossing into oversized-junk-mail territory. That sizing detail sounds trivial; it's actually the single most important thing on this page — we'll come back to it.
How EDDM compares to Valpak — four real differences
1. The envelope problem
The Valpak blue envelope arrives in your mailbox stuffed with twenty to thirty individual coupon cards. The recipient has two choices: open the envelope and sort through the contents, or throw the envelope away. Industry data and our own customer interviews both say the same thing: most households throw the envelope away unopened. If they open it, they typically pull out zero to three cards and discard the rest.
An 8.5×11 EDDM postcard has no envelope. There's nothing to open and nothing to throw away first. The recipient sees your offer the moment they pick up the mail. That's a structural advantage that no amount of clever Valpak design can overcome.
2. The competition problem
A Valpak envelope contains multiple businesses in the same category — three plumbers, two HVAC companies, a couple roofers, several restaurants. Recipients price-shop the cards against each other, picking the lowest offer or none.
Our shared EDDM postcard locks one business per category per drop. If you reserve the plumbing slot, you're the only plumber on that postcard. The recipient's mental choice becomes "call this plumber or do nothing" — not "call the cheapest of three."
3. The cost-per-touch problem
Solo Valpak slots in a market like Greenville typically run $400 to $600 per drop, mailed to 10,000 to 15,000 homes — so $0.04 to $0.06 per home. That looks competitive on paper. But because the envelope conversion problem is so severe, the cost per actually seen ad is much higher.
Our shared 8.5×11 card runs $349 to $649 per slot, mailed to approximately 5,000 homes — so $0.07 to $0.13 per home. Higher per-piece, but every piece is in front of the recipient's eyes the moment the mail arrives. Net effective cost per impression is comparable or better, and the conversion rate per impression is dramatically higher because of the no-competing-offers piece.
4. The tracking problem
Valpak gives you a coupon code and tells you to track redemptions manually. That's 1990s tracking, and it dramatically undercounts response — most callers don't mention they saw you in Valpak.
Every slot on a BynumMailer card has its own unique QR code. When someone scans it, you see the scan in your dashboard within seconds, by day, by hour. Combine that with a unique phone number on the ad and you can prove to yourself exactly what the postcard produced. Direct mail's historical "I can't prove it worked" problem is solved at the slot level.
When Valpak is still the better choice
We'll be honest: there are situations where Valpak still wins. If you need to reach 30,000+ homes per drop, our ~5,000-home coverage isn't big enough. If your customer is specifically a coupon-clipper who actively hunts the Valpak envelope (some casual-dining chains and oil-change shops in this category), the envelope is a good place to be. And if your offer is so weak that being shown next to competing offers actually helps you (rare), the envelope context can work in your favor.
For everyone else — and that's most local Greenville businesses — the shared 8.5×11 postcard does the same job for comparable money with significantly better mechanics.
