A unique QR on every postcard
Each mailer is merged with its own address and a one-per-household tracked code. When it's scanned you know exactly which household responded — no promo codes, no "how did you hear about us?".
For direct-mail marketers
One postcard per household — and every scan tells you who, and where.
Print a personalised mailer for each address, each carrying the resident's own uniquely-tracked QR. They scan and land on a page built for them; you watch the responses arrive live — ranked by region and street — instead of guessing which drop worked.
Response rate you can actually see
Postcards sent versus scanned, live, and broken down by region and street. See which areas pull four times another and post the next drop where the demand already is.
Change the destination after it's posted
The run's already in the post, but every QR is dynamic. Extend the offer, swap the landing page or fix a link without a reprint — the printed codes stay exactly as they were.
How personalised QR codes for direct mail work
Print one mailer per household, each carrying the resident's own uniquely-tracked QR code. Every scan opens their personalised page and lands live on your dashboard — variable-data direct mail with per-household QR tracking, so you see response rate by region and street instead of guessing which drop worked.

Every scan, bot-filtered and honestly counted — by time, place and device. The live numbers you saw on the right.

Frequently asked questions
How does a personalised QR code on direct mail work?
Each mailer is merged with the recipient's address and a unique, tracked QR code using variable-data printing. When they scan, they land on a page built for them, and the scan is attributed to that exact household in your dashboard.
Can I track response rate by area?
Yes. Because every household's QR code is unique, you get postcards-sent-versus-scanned as a live response rate, broken down by region and street — so you can target the next drop precisely.
Can I change the destination after the mailer is posted?
Yes. The QR codes are dynamic, so you can extend an offer, fix a link or swap the landing page after the run is in the post, without reprinting a single card.
Does every recipient need their own QR code?
For per-household attribution, yes — a unique code per address is what lets you tie each scan to a specific recipient. xengo generates them in bulk for your whole mailing list.
Want this on your next mailing?
We'll generate a uniquely-tracked QR for every address in your drop, on your own domain, with the live response dashboard shown above.
