Direct mail that fires the moment something changes.
Merrion automates direct mail for home service contractors. Postcards print and ship when a permit is filed near you, when a home sells on your route, or when a storm hits your zip — reaching the right doormat at the right moment, instead of every house in a generic carrier route.
Carpet-bombing zip codes is expensive. And it doesn't work anymore.
The old direct mail playbook — print 10,000 postcards, blast a carrier route, hope for a 0.3% response — doesn't pay back the way it used to. Postage went up. Generic mailers go in the recycling. The piece that actually gets read is the one that arrives the week something changed at the house.
The contractors winning their markets right now aren't mailing more. They're mailing at the moment of intent— the week a building permit gets filed next door, the week a new family closes on the house, the week after a hail storm crosses the neighborhood.
Merrion is how you do that automatically.
From signal to mailbox. In 48 hours.
Detect — we watch every signal at every address in your area
Merrion continuously ingests permit filings from county records, residential property sales, and NOAA storm and hail data. The moment a property in your service area enters a moment that matters to your business, it lands in the mail queue.

Segment — AI builds the targeted list and writes the postcard
When a signal fires, Merrion builds the right audience automatically — the houses on the same block as a permit, the new homeowners on your route, the addresses inside a confirmed hail polygon. Each postcard is written with the trigger context built in.

POSTCARD COPY
Your neighbor at 8412 Maple Ave just got a new roof.
Apex Roofing crews will be on the block next week. While we're there, we'll inspect your roof at no charge — storm hits in this neighborhood usually take out runs of homes, not just one.

Send — postcards print and ship within 48 hours
Merrion handles the print partner, postage, and tracking. Pieces hit the doormat while the trigger is still fresh — while the neighbor's roof is being torn off, while the new family is still unpacking, while the hail damage is still on the homeowner's mind. Calls and replies route back into your CRM with the trigger attached.

The data that decides who gets the postcard.
Most direct mail vendors sell you a carrier route — every house in a zip, sorted by income bracket, mailed regardless of whether anything is actually happening. Merrion only mails homes where something just changed.
Permits & filings
Real-time ingestion of building, roofing, mechanical, electrical, and pool permits from every major US county. Filed dates, valuations, contractor of record, and exact address.
Home sales & ownership
County recorder transactions and MLS closings. New homeowners replace 70% of their service vendors in the first 90 days — the welcome mailer that beats the competition wins the relationship.
Storm & hail events
NOAA-grade radar and hail polygons cross-referenced with addresses in your service area. The moment a storm clears, mailers go to confirmed-impact homes — not the whole zip.
Neighbor radius
When a permit fires on a block, surrounding homes get a neighbor mailer automatically — same plat, same roof age, same trees. The most-converted variant in residential direct mail, fully automated.
Service history triggers
Pull from your own CRM — HVAC systems installed 12+ years ago, water heaters at end-of-life, last service over 24 months. The customers most likely to need you, mailed before they shop around.
Property intelligence
Build year, square footage, lot size, roof material, and last sale price aggregated per address — so postcard offers and price points adjust to the home, not a generic carrier route.
Built for the trades that live and die by their service routes.
Roofers
Hail polygon triggers fire mailers to confirmed-impact addresses within 48 hours of the storm. Neighbor mailers fire on every roofing permit. Be the first card on the counter.
HVAC contractors
Welcome mailers to every new homeowner on your route, plus replacement mailers triggered when system age in your CRM crosses 12 years. The customers most likely to need a unit, reached before they Google.
Plumbers & water heater
Permit triggers for renovation work in your zone, plus age-based mailers when a water heater install in your CRM crosses warranty. Show up before the leak does.
Landscapers & lawn
New home sales unlock the highest-converting mailer in lawn care — new owners replanning the yard within 60 days. Permit triggers (pools, fences, decks) catch the same household twice.
Pest control
New homeowner mailers + service history triggers (12-month lapse on quarterlies) bring lapsed customers back without a sales call.
Solar & electrical
Permit triggers for additions, EV charger installs, and roof replacements catch the moment a homeowner is already spending on their house. Mail arrives mid-decision.
