Plumbing contractors
A burst pipe is no time to compare plumbers: the household calls a name it already knows or the first credible one it finds. Plavidian prints and mails the postcards, letters and EDDM flats that make that name yours, timed to land ahead of the first storm, the ShakeOut earthquake drill and Thanksgiving.
How mail fits
Mail does two jobs for a plumber: it makes yours the name a household knows before something fails, and it sells planned work. A backed-up drain goes to the plumber the family knows or finds first; a water heater replacement, sewer line or repipe is planned work that gets compared and quoted.
New customers open up at predictable moments: moving in, a crew working on the street, the first storm, a full house over the holidays. Where winters freeze, a pipe-protection card leads the fall; in coastal San Diego, where freezing temperatures are rare (NWS), the rain season, the October ShakeOut drill and holiday kitchens set the calendar.
After the first job, the value is the house: over the years one family owns it, the same home can need drain clearing, a new water heater and remodel plumbing. Maintenance agreements, such as a yearly water heater flush or scheduled root clearing, keep it on the calendar, and your customer file holds the dates (the water heater's install year, the last drain service) that make reminder mail specific.
Campaigns that work
Each starts from a trigger you can schedule or tie to a job, from the rain season to a sewer replacement down the street; the dates fit Southern California.
Eighty-five percent of San Diego's rain falls November through March (NWS), and the City of San Diego makes owners keep the lateral clear of roots all the way to the City main (City of San Diego). A camera inspection before the first storm is planned work with a reason.
California requires standard residential water heaters of up to 120 gallons to be braced, anchored or strapped against earthquakes, and sellers must certify it in writing (Health and Safety Code 19211). The ShakeOut drill, October 15, 2026 for most participants (CDE), gives the card a date; where water is hard, add a flush.
Roto-Rooter calls the day after Thanksgiving the busiest day of the year for plumbers (press release): full houses, extra showers, grease in the disposal. A tip card with the emergency number is worth keeping.
A new owner often has no local plumber yet and inherits a water heater and sewer lateral of unknown age. Sellers of California single-family homes built on or before January 1, 1994 must disclose in writing whether noncompliant plumbing fixtures remain (Civil Code 1101.2 and 1101.4), a ready opening for fixture upgrades.
A trench or lining rig in a driveway is an ad the whole street watches; a card saying you just replaced the sewer line three doors down turns it into proof.
Your customer file holds the dates that say who is due: a water heater flush, root clearing, a maintenance agreement renewal. Each card or letter can name the last service.
Audience and area
Mail the households your trucks can reach within the response time you promise for a backed-up drain or a burst pipe, not the whole county: map last year's jobs, then pick the ZIPs, routes or drawn area that match. California makes a landlord keep a rental's plumbing in good working order (Civil Code 1941 and 1941.1), so repair and replacement offers belong with owners.
The Mailing List Builder counts homeowner households by ZIP, city, district, drawn shape or a radius in feet, from Census data bundled into Plavidian's system; the list is built after you order. The EDDM Route Builder shows the same ground as carrier routes, with owner share as context. Neither tool knows home age or pipe material.
Two lists neither tool covers: your customer file, and property and HOA managers, whose buildings' backflow assemblies must be tested every year by a certified tester under the State Water Board's cross-connection rules (Las Virgenes MWD).
EDDM or a mailing list
Use EDDM when every home on the routes around your shop or a sewer job could use your emergency number or a drain cleaning. Use an addressed list when only owners should get the offer, as with a water heater or sewer line replacement, because EDDM reaches every residential address on a route and cannot pick out owners.
Plavidian mails EDDM on its own permit through the business mail entry unit, so the Retail limit of 5,000 pieces per ZIP Code per day (USPS) does not apply; jobs start at 200 flat-size pieces. Where apartments dot single-family routes, price both ways: every door at saturation postage, or fewer owner addresses at a higher rate plus the list.
Mail pieces
Pick the piece by what it carries: an emergency number, a flat-rate price menu with job photos, or one customer's service history.
How it runs at Plavidian
The order a storm-season card runs in, from the in-home week to the scans that tell you when to staff the phones.
Pick the week the card should land, such as the week before the ShakeOut, and the Mail Date Planner works back to the artwork, proof and mail dates.
Count owner households, with estimated postage, in the ZIPs or shape your trucks cover.
Plavidian CASS-processes and deduplicates your customer file, running NCOALink when needed; with a free account, Mailing Blueprint™ prices its postage first, with a +/- 5% planning range.
Plavidian Studio™ draws the bleed, safe zone and address area so the license number survives the trim; Print File Check grades your own PDF A to F.
Printing, addressing and inserting run at Plavidian's Vista plant, and every job, including work an approved vendor produces, is held to the Plavidian Standard™.
Plavidian mails on its own USPS permits, so you need none, and enters mail locally or drop-ships it to facilities near the homes in your dispatch zone.
On letter-size pieces such as a reactivation letter, the optional Plavidian Sentry™ add-on reads each piece as it is addressed and matches it to its record.
Plavidian Insight comes with every mailing: USPS scans as the cards move, so you know when to staff the phones.
What it costs
Five choices set the price of plumbing mail: how many homes sit inside your dispatch zone, a postcard or an EDDM flat and its stock, whether the addresses come from your customer file or a purchased list, the postage class and entry, and how many drops the rain season takes. Printing and postage are priced and paid separately.
Printing can be paid by card. USPS postage is paid by check or wire, and mail is released once postage has cleared.
Measuring results
Match booked jobs to what you mailed: before the cards print, give each campaign its own offer code and a phone number or landing page used only on that mailing, and tag the source of every booked drain, water heater and sewer job in your dispatch software. After the in-home week, check new jobs against the addresses or routes you mailed.
Plavidian Insight, included with every Plavidian mailing at no separate charge, follows addressed pieces by their Intelligent Mail barcodes through USPS Informed Visibility scans, so the call log can sit beside the days the mail moved. Scans show mailstream visibility, not proof of delivery, and complete scan data is not guaranteed for every piece.
Addressed mailings can add a USPS Informed Delivery® campaign through Plavidian Impression™: subscribers see a color ride-along image that links to your booking page (USPS). Plavidian Impression is not affiliated with or endorsed by USPS.
Rules to know
A plumbing postcard is contractor advertising. The first three rules are California's; the last two apply nationwide.
General information for planning a mailing, not legal advice. Confirm the rules that apply to you with your regulator or counsel.
Questions
They can, when they reach owners your trucks can serve before the emergency, with one clear reason to call. Plavidian does not quote response rates, because the plumbing figures published online are mostly unsourced vendor claims; an offer code on your own cards will show what yours bring.
There is no standard number. Mail the owner households your trucks reach within your promised response time, in monthly batches small enough that your crews could answer the drain and water heater calls and you can afford to mail the same homes again.
The emergency number, one offer with its conditions (is the trip charge waived?), the area you serve and your CSLB license number. Skip the stock line "licensed, bonded and insured": California bars advertising the license bond as "bonded," and "insured" must name the type of coverage.
It works when the routes around your shop are mostly single-family homes and the offer suits every door, such as your emergency number or a drain-cleaning offer. EDDM cannot select owners, so every apartment on a route gets a piece too, and Plavidian's EDDM jobs use 6.5x9, 8.5x11 or 9x12 flats, not 6x9 or 6x11 postcards.
Your own customer file first, then owner households in your dispatch zone, new homeowners in the ZIPs you serve, and property managers for commercial work.
Plavidian CASS-processes every addressed list and supplies consumer, business and new-mover lists through licensed data providers; a monthly new-mover mailing is a fresh list each month, not an automatic program.
Order early enough for the cards to land in October, ahead of the November to March rain season. Work back from that in-home date through USPS transit and production, which starts after proof approval; order cutoffs are 12:00 PM Pacific, or 9:00 AM for a 2-day rush on certain products.
Storm-response mail cannot be printed overnight; Turnaround Times lists current production windows.
