Direct-mail glossary

Response rate

Response rate is the percentage of mailed pieces that generate the intended action — a phone call, a QR scan, a booked appointment, or a website visit — divided by the total number of pieces mailed.

Why it matters

Direct mail response rates vary widely depending on list quality, offer strength, creative execution, and whether you are mailing to a cold prospect list or a warm house list (existing customers or patients). Industry research from the Data & Marketing Association (DMA) typically cites response rates of roughly 1–2% for prospect (cold) lists and 3–5% or higher for house lists, though any individual campaign can fall well above or below these ranges. Response rate alone is only part of the picture: a 1% response rate on a mailing of 500 cards with a high-value offer may deliver far better ROI than a 3% rate on a generic low-margin promotion. Track response rate alongside cost per acquisition (CPA) for a complete view of campaign performance.

How CardCadence handles it

CardCadence makes response measurable on every mailing via trackable QR codes, each one resolving to a link unique to the recipient it was mailed to. Your dashboard shows scans by campaign, so you can calculate a real response rate from each drop rather than leaning on industry estimates. One honest caveat: this measures scans, not every response. A customer who reads the card and simply picks up the phone is a real response the QR will never record, so treat your scan rate as a floor rather than the whole picture. Used that way, the data is still the fastest way to compare creative variations, audience segments, and mailing schedules over time.
