How It Works · The KDO Mailing Process
We run list sourcing, design, printing, postage, and tracked delivery as one accountable team — under one SLA, in one Cincinnati facility. No vendor relay. No missed drops. No six-week limbo between "we approved it" and "it landed."
Day 0 → Day 9
Verified across more than 18,400 campaigns shipped since 2017, our standard turnaround on custom-designed pieces is nine business days from approved artwork to in-home delivery. Here is what happens on each day, and which KDO team owns it.
Your designer or ours delivers a press-ready PDF. Our prepress team runs a four-point technical check: bleed, color profile, postal indicia, and mailpiece design compliance.
Owned by: Prepress Lead
We pull, dedupe, and NCOA-link your audience against 240+ attributes. Every record passes USPS delivery-point validation before it touches a press plate.
Owned by: Data Engineering
Six offset presses and two HP Indigo digital lines run 24/6. Variable data merges per-recipient copy and a unique MatchBack QR or URL into each piece.
Owned by: Production Manager
USPS inducted, tracked via Intelligent Mail barcodes. MatchBack attribution begins firing the moment mail enters the local stream — online visits, form fills, and purchases are tied back to the mailed piece.
Owned by: Mail Operations Director
Heads-up on custom design: if we are designing the piece from scratch (not just printing yours), add 3–5 business days for concept and revision. Same-day or 24-hour dispatch is not offered on custom work — minimum nine business days.
One team, four workstreams
Most direct mail programs run across a list broker, a freelance designer, a third-party printer, and a mail house. Each handoff adds days and dilutes accountability. At KDO, all four workstreams sit inside one team with one production director, one SLA, and one invoice.
Our four data engineers build, clean, and model your audience against 240+ demographic, behavioral, and modeled-propensity attributes. NCOA, dedupe, and USPS DPV validation are run in-house.
Twelve in-house designers work alongside three USPS-certified Mailpiece Design Analysts — one of only 47 providers nationwide to maintain MDA certification in-house rather than outsourcing.
An 84,000 sq ft Cincinnati facility running six offset presses and two HP Indigo digital lines, 24 hours a day, six days a week. Capacity we own, not lease — so we control the schedule.
We induct directly with the USPS, applying the right automation or saturation rate class for your campaign — and tracking every piece via Intelligent Mail barcodes until it is scanned at the carrier route.
Inside the production floor
Most direct mail shops outsource their press capacity. We own ours outright. The Cincinnati facility houses six offset presses, two HP Indigo digital lines, a full bindery and insert operation, and a 60-person production team working a six-day shift pattern built to protect the nine-day SLA.
Capacity isn't a sales pitch — it shows up in our on-time dispatch numbers. In 2024 we processed 9.2 million triggered mailings via API and 18,427 cumulative campaigns since 2017, with a 99.94% on-time dispatch rate.

MatchBack attribution
We treat direct mail as a measurable channel, not a branding tactic. Each mailed piece carries a unique MatchBack code — a QR, a tracked URL, or a stitched identifier — that attributes downstream site visits, form fills, and purchases back to the exact recipient.
In 2024, our proprietary MatchBack engine tied 87% of mailed pieces to a digital action within 30 days — the highest attribution rate in the independent direct mail space per the 2024 Print & Postage Benchmark Report. That's how you measure direct mail next to paid social, search, and email in one dashboard.
