EDDM vs. Targeted Postcards: The Real Cost-Per-Booked-Job Math

If you've ever priced out postcards, you've noticed the gap: an EDDM (Every Door Direct Mail) drop can run 50–65¢ a piece all-in, while a targeted campaign runs 80¢ to a dollar or more. To an owner watching the budget, EDDM looks like the obvious choice.

But per-piece price is a vanity metric. You don't deposit postcards; you deposit jobs. The only cost that belongs in your decision is cost per booked job — and once you run that math, the cheaper card is usually the more expensive one.

What EDDM actually is

EDDM is a USPS program that delivers your card to every mailbox on the carrier routes you pick. There's no mailing list — pieces are addressed to "Resident" or "Current Resident" — which is exactly why it's cheap: no list to buy, no addressing, and postage in the low-20-cents range per piece.

The trade-off is baked into the design. You cannot choose who gets the card. Every apartment where the renter will never buy a repipe, every PO box, every vacant house, every household that called your competitor last month — they all get one, and you pay for all of them. One industry breakdown of a typical 5,000-piece EDDM drop found roughly 800 of those addresses were apartments, PO boxes, and drop addresses — 16% of the budget mailed to people who mostly can't buy the service. And because EDDM pieces can't be personalized, you also give up the response lift that comes with it (adding a recipient's name alone lifts response by up to 135%, per ANA/DMA data).

The response-rate gap

The benchmarks tell the story plainly:

• Blanket/EDDM drops: 0.5–2% average response (Taradel)
• Home services mail, well-targeted and in season: 1.5–4.5% (industry benchmarks); blanket or off-season drops sink to 0.8–2%
• Targeted prospect lists generally: 2–4.4% (ANA/DMA)
• Your own past customers: 5–9% (ANA/DMA)

The pattern is one-directional: the more the audience resembles people who already buy from you, the higher the response. Targeting built from your own job history — mailing the households that statistically look like your best customers — is how cold mail gets pulled toward the top of those ranges.

The worked comparison

Here's the math side by side, using published benchmark response rates and ServiceTitan's ~38% average booking rate on answered calls, with a $340 average ticket. The EDDM column mirrors what a typical shop actually does: 10,000 cards blanketed twice a year. The targeted column mails fewer than half the cards at a higher per-piece price.

Look at what happened. The targeted campaign spent 39% less money, mailed 60% fewer cards, paid 53% more per piece — and produced as many or more booked jobs, at roughly one-half to one-third the cost per job. The per-piece "savings" of EDDM were an illusion the whole time; they were spent buying postage to households that were never going to call.

And this comparison is generous to EDDM in one important way: it assumes you can even measure it. Most blanket drops go out with no tracking number and no unique QR code, so the owner never learns the response rate at all — the phones just "seem busier." You can't cut a loser you can't identify, which is how shops end up repeating a $5,800 drop twice a year for a decade on faith.

To be fair: when EDDM is the right call

We'd rather you trust our math than our marketing, so here's the other side. EDDM genuinely makes sense when:

You have no job history yet. Targeting from your own data requires data. A brand-new shop with a few dozen jobs can't model its best neighborhoods — a smart EDDM drop into homeowner-heavy routes near the shop is a legitimate way to generate the first dataset. (Even then: put a tracking number on it, so the first drop teaches you something.)

Your service area is one dense, uniform neighborhood. If 90% of the addresses on a route genuinely fit your customer profile — say, a single-builder subdivision of 15-year-old homes for an HVAC replacement offer — blanketing it wastes little.

The offer is truly mass-appeal. Restaurants, gyms, and grand openings can work at saturation economics because nearly every mailbox is a plausible customer. A $12,000 repipe is not that kind of offer.

You're deliberately buying awareness, not response. Some shops blanket their home ZIP for name recognition and measure nothing. That's a valid branding choice — just don't call it lead generation, and don't judge it by lead-generation math.

One more upgrade worth knowing even if you never work with us: full-service saturation mail beats raw EDDM at nearly identical cost. Saturation programs use an occupant list, which lets you strip out apartments, PO boxes, vacancies, and businesses while keeping saturation postage rates — several mail-industry analyses find it typically nets out cheaper and higher-response than true every-door EDDM. If you're going to blanket, blanket with a filter.

The decision rule

Don't ask "what does the card cost?" Ask three questions in order:

1. What's my expected cost per booked job on each option? (Spend ÷ [cards × response rate × booking rate].)
2. Will I be able to prove the answer afterward? If a campaign has no dedicated tracking number or QR code, its real performance will be unknowable — which should disqualify it from serious budgets.
3. What does this mailing teach the next one? Targeted, tracked campaigns compound: each drop reveals which neighborhoods, offers, and cards to scale. Blanket drops teach nothing, so drop #20 performs like drop #1.

In our six-month case study, replacing blanket drops with tracked, targeted campaigns took the sample company from an estimated $150–$300 per booked job to a measured $44 — not by spending more, but by aiming and counting.
