PlanPost — Direct-mail lead generation for UK builders and construction firms. PlanPost turns UK planning applications into AI-written, branded letters posted straight to homeowners
PlanPost helps UK builders and construction firms win more local work without cold calling or buying shared leads. It monitors planning applications across all 389 UK local planning authorities and matches newly approved projects to each builder's trade, project type and service radius. For every match, PlanPost's AI writes a personalised letter in the builder's own branding, then prints and posts it to the homeowner, reaching them exactly when they are planning building work. A built-in pipeline tracks leads from sent to won, with QR-code response tracking and automated follow-up letters on higher tiers. Plans start at £39 per month with no long-term contract.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
