When your customer leaves a 5-star Google review, our system detects it automatically via webhook. AI generates a personalized postcard featuring that review, and PostGrid prints and mails 20 postcards to neighbouring homes the same day. Neighbours see real proof from their street and call you.

Same day. Our webhook fires within minutes of the review posting. PostGrid prints and enters the mail stream the same business day. Most neighbours receive the postcard within 2-4 business days via Canada Post.

Any home service contractor: roofers, HVAC technicians, plumbers, electricians, landscapers, painters, general contractors, window installers, fence builders, and more. If you do work at residential homes and want the neighbours to know, this system works.

We only work with ONE contractor per trade per postal code zone. If you are the roofer locked into L2E, no other roofer can use the Radius Engine in that zone. First to claim wins. This protects your investment and prevents competitors from using the same system in your area.

No. The system is fully automated. Do great work, encourage a Google review, and the Radius Engine handles the rest. You get a tracking dashboard so you can see every postcard mailed and every territory covered.

The average home service job is $3,000-$15,000. Close just ONE job from 500 postcards ($697 Block Buster package) and that is a 4x to 21x return on investment. Most contractors close 2-5 jobs per campaign.

Yes. Call 289-228-7021 or use our fast quote page and we will send you a sample proof within 24 hours at no charge. You approve every design before a single postcard is mailed.
