The benchmark numbers and where they come from
The figures every vendor quotes trace back to response-rate panels run by the Data & Marketing Association (now part of the ANA) and to industry reports that carry the lineage forward, most prominently Lob’s State of Direct Mail series. The headline numbers as commonly cited in 2025 and 2026:
| Metric | Commonly cited figure | Source lineage |
|---|---|---|
| Average direct mail response | 4.4% | ANA/DMA response-rate panels |
| Email response, same studies | 0.12% | ANA/DMA panels (the famous 36x gap) |
| House list (your customers) | 5 to 9% | ANA/DMA panels |
| Prospect list (cold names) | 2.0 to 4.4% | ANA/DMA panels |
| Postcards specifically | 4.25 to 5.7% | Panel splits reported by Lob and others |
| Direct mail ROI | ~161% (vs ~44% email) | Lob State of Direct Mail 2025 |
What cold campaigns actually see
The most honest public data point in the industry comes from PostcardMania, which mails 140,000 to 200,000 postcards a week promoting itself and has disclosed receiving roughly 200 direct responses a week: about 0.11 percent per dropon generic cold B2B mail. Their clients’ prospecting campaigns commonly report 1 to 2 percent. The practical planning ranges we suggest:
- Cold prospect list or cold saturation: plan on 0.5 to 2 percent, and treat anything above 2 percent as a win to study and repeat.
- Warm saturation (the neighborhood already sees your trucks or storefront): 1 to 3 percent is a reasonable ambition.
- House list: the 5-to-9-percent benchmark range is real. Nothing else in marketing responds like people who already know you.
The five variables that move response most
- List quality. The gap between house and prospect lists is roughly 2x in every study ever run. Who you mail beats everything else on this page.
- Repetition.Lob’s research finds campaigns with three or more touches lift response by up to 50 percent, and practitioners routinely report the third touch outperforming the first. One-and-done mail is where budgets go to die.
- The offer. A concrete, expiring offer with a plain call to action consistently beats brand-only cards for measurable response.
- Personalization. Studies of personalized URLs and content report response lifts from 5 to 40 percent versus generic pieces.
- A response mechanism. When a QR code is present on a mail piece, studies find it carries 64 to 76 percent of all responses. A card with no scannable code, no offer code, and no tracked number cannot be measured at all, and unmeasured mail is indistinguishable from mail that did not work.
How to measure your own rate honestly
Response rate is responses divided by delivered pieces. Getting it honest takes three disciplines:
- Put the mechanism on the card before mailing. A per-campaign QR code or offer code makes attribution automatic. This is retroactively impossible: the printed piece is frozen the day it mails.
- Count a window, not a day. Mail responses arrive over one to three weeks after the in-home date. Judge a drop at day 21, not day 3.
- Refuse rates on tiny sends.Twenty cards and one response is not a 5 percent response rate, it is an anecdote. StampSherpa’s own dashboard refuses to display a response rate below 25 cards mailed, and we recommend the same floor however you mail. (Every card we print carries a scannable code, so counting is automatic; rates appear only when they mean something.)
What we will publish next
StampSherpa tracks scans on every card it mails. As our customers’ volume grows, we will publish anonymized, methodology-first response benchmarks by industry and campaign type: real scan data from real small-business mail, with sample sizes attached. If you want honest numbers instead of recycled averages, run your first tracked campaign and you will be reading your own.
