When you operate a local plumbing company, the challenge isn’t just providing great service… it’s making sure homeowners in your area know you exist. Every Door Direct Mail (EDDM) is a U.S. Postal Service program that allows you to blanket entire neighborhoods with oversized postcards without buying a mailing list. For plumbers, that means you can saturate streets within your service radius quickly and affordably while complementing your online marketing efforts. Think of EDDM as the analog counterpart to geofenced ads… you’re physically putting your name in every mailbox within a chosen radius, which makes later digital retargeting even more effective.
Why EDDM Is a Smart Local Marketing Tool
Too many contractors treat EDDM as a one‑and‑done postcard blast. A smarter approach is to layer your campaigns throughout the year so your name stays familiar. When your truck is in a neighborhood, schedule an EDDM drop soon after to reinforce your presence. Pair the drop with branded leave‑behinds like business cards or flyers. Over time this consistent visibility makes your company feel like the go‑to choice in the area. A golden nugget here is to segment routes by house age and income: older homes may need repiping, while higher‑income areas respond better to premium maintenance plans.
EDDM also works well with targeted direct mail and door hanger campaigns. By coordinating offers across all print pieces, you create a unified message that reinforces your brand. Use the generous postcard space to highlight membership plans, financing options and emergency services. Don’t forget to mention that your technicians are licensed, insured and background‑checked… homeowners want reassurance before inviting anyone into their home.
Design and Offer Strategies
An effective EDDM piece does more than announce your company; it solves a problem homeowners care about. Use a large, eye‑catching headline such as “Avoid Costly Pipe Bursts This Winter” or “Slow Drain? We Can Help!” Include a compelling offer… perhaps a discounted drain cleaning, a free inspection with any repair, or a loyalty discount on annual maintenance. Visuals matter: before‑and‑after photos of a plumbing job or simple diagrams of common issues grab attention. Make sure your call‑to‑action is clear and easy to follow: a phone number in bold type, a QR code that links to an online booking page, or a promo code they can mention when calling.
- Choose the right size: Oversized postcards (e.g., 6.5×9 inches or 8.5×11 inches) stand out more than small mailers.
- Show proof: Include short testimonials, licensing badges or “locally owned since 1998” to build trust.
- Use tracking: Assign a unique phone number or URL to this campaign so you know exactly how many calls it generates.
- Time your drops: Schedule multiple mailings during peak seasons (e.g., before winter or the rainy season) instead of a one‑time blast.
- Add something tangible: Consider including a fridge magnet or a perforated coupon that homeowners can keep for emergencies.
Layering and Timing Your Mail Drops
Identifying the right routes is crucial. Look at your customer database to find ZIP codes that produce the most revenue, then choose adjacent carrier routes. For example, if you frequently service an older neighborhood with cast‑iron pipes, target surrounding areas with similar housing stock. Use USPS route maps to verify the number of homes per route and estimate your mailing volume. When you’re just starting, test a few routes with smaller quantities; once you see results, scale up and repeat. Pair EDDM campaigns with postcards and flyers for consistent branding across multiple touchpoints.
Another pro tip is to plan EDDM drops around your seasonal service calendar. Promote sump pump inspections in early spring, water heater flushes in the fall and pipe insulation before winter. If your company offers maintenance memberships, highlight the benefits as part of your mailers and direct recipients to a dedicated landing page on your website. Use your website and branding to reinforce the same colors, fonts and messaging across all channels.
Measuring and Scaling Success
To understand the return on your EDDM investment, you need accurate tracking. Use call tracking software with unique numbers for each mail drop. Create dedicated landing pages so you can see how many website visitors come directly from your mailers. Train your dispatchers to ask callers how they heard about you and record the response in your CRM. Over time, compare results by route, offer and design to see which combinations produce the most calls and revenue. Adjust your mailing frequency and creative accordingly. The beauty of EDDM is that it’s scalable; once you find a winning formula, you can replicate it on other routes with similar demographics.
Don’t forget to nurture leads after the mailer. Follow up with email or SMS reminders, invite contacts to join your newsletter and provide seasonal maintenance tips. By combining offline outreach with digital follow‑up, you build relationships that last longer than a single repair.

Frequently Asked Questions
How does EDDM differ from regular postcard mailings?
EDDM allows you to send oversized mail pieces to every home on selected postal routes without purchasing or managing a mailing list. You pay a flat per‑piece rate and drop the cards off at a designated USPS facility. Standard postcard campaigns typically require a targeted list and may have different postage rates.
What size should a plumber’s EDDM mailer be?
The USPS has specific size requirements. Common sizes include 6.25×9 inches and 8.5×11 inches. Larger cards stand out more but also cost slightly more to print and mail. Choose a size that allows you to include a strong offer, images and contact information without overcrowding the layout.
How many times should I mail to the same route?
Repetition is key. Many homeowners need multiple touchpoints before they call. We recommend at least three mail drops over a few months to the same route, adjusting your offer and creative each time. Track results to see whether frequency improves response.
