Most plumbers do a great job and then never hear from that customer again. This guide shows you how to automatically follow up on quotes, send seasonal maintenance reminders, and turn satisfied customers into a referral engine, without picking up the phone.
| Tool | Free Plan | Best Feature | Best For |
|---|---|---|---|
| Mailchimp | 500 contacts, 1K sends/mo | Drag-and-drop seasonal campaigns | Most plumbers starting out |
| HubSpot | 1,000 contacts, full CRM | Quote follow-up + deal tracking | Plumbers who also want a CRM |
| Jobber | $49/mo (includes email) | Connects to jobs directly | Already using Jobber for scheduling |
| ActiveCampaign | No (from $15/mo) | Most powerful automations | High-volume plumbing businesses |
Start here: Mailchimp free → for campaigns and HubSpot free → for quote follow-up. Both connect to Jobber via Zapier if you need it.
You give a quote. The homeowner says "I'll think about it." Then silence. A 3-email follow-up sequence runs automatically and recovers 15–25% of quotes that would otherwise go cold.
The key insight: most homeowners don't choose your competitor, they just get busy and forget. A friendly follow-up at the right moment is all it takes.
Setting it up in HubSpot (free): Create a deal in HubSpot when you send a quote. Set up a simple Sequence (under Sales → Sequences): Day 3, Day 7, Day 12 emails. HubSpot will pause the sequence automatically when the customer replies.
Using Jobber: Jobber has built-in quote follow-up notifications. Go to Settings → Client Notifications → Quote Follow-up and enable automatic reminders at 3 days and 7 days.
HubSpot shows you exactly when a customer opens your follow-up email. That's your signal to call within the next 30 minutes while you're top of mind. Plumbers who call within 5 minutes of a quote being read close 4× more jobs than those who wait.
The 24 hours after a job is your highest-trust moment with a customer. Use it. An automatic post-job email does three things: thanks them, gives care instructions, and asks for a Google review while the experience is fresh.
In Jobber: go to Settings → Client Notifications → Job Follow-up. Enable automatic email 24 hours after job completion. You can customize the message to include a Google review link.
In Mailchimp + Zapier: Build a Zap triggered by "Job marked complete in Jobber → Wait 24 hours → Send email in Mailchimp." Use the template below.
Plumbing maintenance is cyclical. Smart plumbers get ahead of the season, sending an email before homeowners even realize they need a service call. These campaigns fill your schedule during predictable slow periods.
"Time to winterize your pipes and water heater before the first freeze. We're booking fast, schedule your inspection now."
"Cold weather pipe protection checklist + our emergency line number for freeze emergencies."
"Post-freeze pipe inspection season. Check for winter damage before it becomes a summer emergency."
"Annual water heater flush. Most homeowners never do this. It extends heater life by 3–5 years."
Build these as 4 scheduled broadcast emails in Mailchimp. Set them to send in early October, late November, mid-March, and mid-June every year. Each takes about 15 minutes to write using the templates below.
Your best source of new customers is the customers you already have. A referral request 90 days after a completed job, when the good experience is still in mind but far enough out that it doesn't feel pushy, converts surprisingly well.
Build a simple Customer Journey in Mailchimp: trigger 90 days after job completion → send referral request email. If they click but don't refer, follow up in 14 days with a small incentive (e.g., $20 off their next service for a successful referral).
Keep it simple: "If you know anyone who needs a plumber, I'd love the introduction. I'll take great care of them, and I'll knock $20 off your next service as a thank-you."
A monthly email with 2–3 plumbing tips keeps you top-of-mind for the next time something breaks. The goal isn't to teach homeowners to fix their own plumbing, it's to be the plumber they think of first when they need help.
Topics that work well: "Signs your water heater is about to fail," "3 things that clog drains you wouldn't expect," "When to call a plumber vs. handle it yourself," "How to turn off your water in an emergency."
Keep it short: one tip, one photo, one sentence about your business. Schedule it for the first Tuesday of every month in Mailchimp.
Add this to the bottom of every tips email: "Found this useful? Forward it to a neighbor who could use a reliable plumber." This single line generates 2–4 new leads per month for most plumbers, completely free.
The situation: Marcus ran a solo plumbing business in Portland with 4 years of customer data in Jobber, about 380 past customers. He ran Google Ads to generate new leads ($800/month spend) but had no system for reaching past customers.
What he built: Exported past customers from Jobber into Mailchimp. Set up 4 seasonal maintenance campaigns. Added a quote follow-up sequence via HubSpot. Launched a post-job review request. Total setup: one Saturday afternoon.
He later reduced his Google Ads budget by $400/month, covering the entire cost of Mailchimp's paid plan with budget to spare.
