37 data sources. One letter. Zero waste.

The Problem

Most direct mail is untargeted junk. Companies buy generic mailing lists, send identical letters to everyone, and get 0.5% response rates. 99.5% goes in the bin. That's not marketing — that's littering with postage.

Our Approach

We built something different. We analyse 37 government and public data sources — from Companies House business filings to ONS Census demographics, council tax bands to planning applications — to understand exactly who lives and works in your target area. Then we send a lumpy mail letter (with a branded pen inside) to the people most likely to need your service. Warm, targeted direct mail like this averages a 7.2% response rate and £9 back for every £1 spent (JICMAIL Response Rate Tracker, 2025), versus around 0.9% for untargeted cold mail (JICMAIL, 2025).
