Letter Radius automatically sends real, handwritten letters to homes near your completed jobs — so your next customer is already expecting your call.
March 18, 2026
Dear Michael,
I was just at your neighbor's home on Oakwood Dr helping them with their AC system before summer hits.
I noticed a few homes on your street might be due for a tune-up. We're offering neighbors a free 21-point inspection this month.
Give us a call anytime — happy to help.

Integrates with the tools you already use
Every time your truck pulls away from a job, you leave behind a neighborhood full of potential customers who just watched you work — and have no way to reach you.
Awkward, time-consuming, and most techs won't do it. You're leaving money on every job.
Homeowners scroll past your ads. Average cost per lead keeps climbing while response rates drop.
Neighbors see your van, think "I should call them," and never do. There's no follow-through.
Letter Radius bridges the gap between your completed job and the 20+ neighbors who need the same service. A real, handwritten letter lands in their mailbox within 48 hours — personal, tangible, and impossible to ignore.

1,000 letter minimum per month
"We went from 0 neighbor referrals to 15-20 new calls a month. The letters pay for themselves three times over."
"My techs hated door knocking. Now they just do their job and Letter Radius handles the rest. Our close rate on these leads is insane."
"The handwritten letters are a game changer. Customers call us saying 'I got your letter' — they already trust us before we show up."
We use precision pen plotter machines that hold a real ballpoint pen and write on real stationery. Every letter has natural pen strokes — not a printed font designed to look like handwriting. Recipients can feel the pen indentation on the paper.
Our system uses the job site address from your field service software and automatically identifies the nearest residential addresses using proprietary radius-based geocoding. We typically target the closest 20 homes, but this is fully configurable.
1,000 letters per month at $2 per letter. No long-term contracts — you can cancel anytime. Most customers scale up quickly once they see the ROI.
Letters are written and in the mail within 24-48 hours of your completed job syncing to our system.
Absolutely. We work with you to create custom templates that match your brand voice. You can have different templates for different service types, promotions, or seasons.
Yes. Every envelope includes a physical business card for the technician or your company. It gives the recipient something tangible to hold onto and call.
Handwritten mail averages a 98% open rate and our customers typically see 1-3% direct response rates — dramatically higher than digital ads or printed mailers. Even a 1% response rate is usually highly profitable at $2/letter.
