Email Marketing for Plumbers
One email a year, sent in the right week, beats twelve sent monthly
Your customers do not want to hear from you monthly
A bathroom refit is £1,850. A boiler replacement, £1,670. A shower installation, £840. A leak repair, £235. A blocked drain, £215.
Here is the honest position. Nobody wants a plumbing newsletter. There is no plumbing news. A monthly email from a plumber is opened twice, ignored eight times and unsubscribed from on the eleventh, and by then you have trained several hundred past customers to delete anything with your name on it.
That last part is what makes over-sending genuinely expensive rather than merely ineffective. You get one attention budget with a customer and spending it on filler means the email that mattered arrives to somebody who has stopped looking.
So the programme for a plumber is small, deliberate and built around a handful of moments when an email is genuinely welcome. Done that way it outperforms monthly sending by a distance, and takes a fraction of the effort.
The moments that are actually worth an email
The last week of August. This is the most valuable send in your year and it is not close. Boilers fail in the first cold fortnight, and the people whose boiler is fifteen years old, or who had it patched last winter, are the ones who will spend £1,670 in November with whoever can get there. Reaching them in late summer — while it is warm, while they can plan, while you have capacity — converts a panic purchase into a booked job at a sensible price.
The first hard frost warning. Short, practical, genuinely helpful: where the stopcock is, what to do about a frozen condensate, when to worry. It gets opened because it is relevant that week, and it puts your name in front of people days before the failures start.
Twelve months after a bathroom or boiler. Not a sales email. A check-in with the warranty position, the service the boiler warranty depends on, and an offer to look at anything that has annoyed them. It rescues small problems before they become somebody else’s callout.
The dormant emergency customer. You attended once, at nine at night, fixed something, and were never heard from again. One email a year to that group is the cheapest work available to you.
The ratio
A boiler is £1,670. Our Seen package is £29 a month — £348 a year. One boiler replacement covers nearly five years.
The August email is the one to judge this on. A list of five hundred past customers, a two per cent conversion on boiler replacement, is eight jobs at £1,670 — £13,360 from a single well-timed send. Even at a quarter of that it settles the argument.
What we’d actually send
The August boiler email, segmented so the people with old or previously repaired boilers get a directly relevant version and everyone else gets the general one.
The frost note, drafted in September and held ready, sent the day the forecast turns.
A twelve-month check-in running automatically off install dates, so it happens without anybody remembering.
An annual dormant note to emergency-only customers — brief, warm, and mostly a reminder that you exist and are still local.
A bathroom planning email in January, to anyone who has enquired about one and not proceeded. Bathrooms are decided slowly and January is when people look at theirs and lose patience.
That is five sends a year. It is deliberately not more.
What good looks like at twelve months
- Five sends, not fifty, and an unsubscribe rate low enough that the list is still there next year
- The August email producing bookings before the cold snap rather than during it
- Boiler replacements arriving from people you last saw for a £235 leak
- The frost note ready to go rather than written in a panic
- A dormant list that is actually being used, having previously been a folder of invoices
The mistakes we see most
Monthly newsletters. They burn the list and produce almost nothing. This is the single most common error in trade email.
Sending the boiler email in October. The failures have started, the good customers have already booked somebody, and you are competing on who can attend today.
Treating emergency customers as one-offs. They are the largest untouched group in most plumbing businesses and they remember you better than planned customers do.
No segmentation at all. A boiler email to somebody whose boiler you fitted last year is a small insult and an easy unsubscribe.
The first ninety days
Weeks 1–4. We build the list from your job history and split it by what people actually had done — boiler, bathroom, emergency callout, everything else.
Weeks 5–8. The next seasonal send written and scheduled, whichever it is. If we are inside six weeks of August, that takes priority over everything else on this page.
Weeks 9–12. The automatic flows — twelve-month check-in, frost note held ready — plus the dormant email to emergency customers.
At ninety days the measure is bookings from named people already in your records, not new enquiries. This service is about the customers you have.
Where this lands in Gaffer
Boiler installs carry their date and warranty terms, so the twelve-month check-in and the annual service prompt both run from the real record rather than from anyone’s memory.
Job types are on the customer record, which is what the August segmentation runs on — an email that reaches boiler-aged houses and skips last year’s installs.
And a reply comes back as an opportunity with the previous job attached, so the quote is out the same day, which in the week before the cold turns is usually the whole contest.
If you have no email addresses, start here
Most plumbers reading this have several hundred past customers and email addresses for perhaps forty of them. Everything above depends on fixing that, and it is more straightforward than it sounds.
The addresses you already have are scattered rather than missing. They are in sent invoices, in booking confirmations, in your accounting software, in old quote emails and in the messages people sent when they first got in touch. Pulling those together typically recovers half a list in an afternoon, and it is the first thing we do.
The rest is about capture from now on. An email address asked for at the point of booking, so the confirmation can be sent to it, is given without hesitation — it is a natural part of the transaction rather than a marketing request. Asked for at the end of a job, after the invoice, it feels like something else entirely and half of people decline.
Two other habits worth building. Send the invoice by email rather than handing over paper, which both improves your payment times and gives you the address. And when somebody rings out of hours in a panic, take the address for the paperwork while you are booking the visit, because emergency customers are precisely the group you will otherwise never have a way of reaching again.
Six months of that and the August email has a list worth sending to.
Questions plumbers ask
Only five emails a year? Yes, and they will outperform sixty. This trade punishes over-sending harder than any other on this site.
What about emergency work — can email help there? Indirectly. Somebody who has heard from you twice this year searches your name rather than “emergency plumber”, and that is a completely different conversation.
How big does the list need to be? Five hundred names is a serious asset. Most plumbers with a few years behind them already have more than that in their job history.
Will I get complaints? At five sends a year, about relevant things, very rarely. Complaints are a symptom of frequency and irrelevance, and both are controllable.
