Plumbing Email Marketing: Expert Tips to Win More Work

How to build an email list for your plumbing business

Before you can send marketing emails, you need a list of customers who have already agreed to be contacted by email.

Most plumbing businesses already collect email addresses during normal operations. Your goal is to capture those emails consistently and give people a clear reason to stay connected with your business. Here’s how to build your email list:

1. Collect emails during service calls

One of the easiest ways to build an email list is to collect addresses during everyday customer interactions.

When technicians complete a job, they can confirm the customer’s email address before sending the invoice or receipt. Office staff can also ask for an email when booking appointments or creating customer records.

Over time, this creates a growing list of past customers who can receive plumbing service updates, maintenance reminders, and follow-up messages.

Just make sure you get the client’s permission to send them marketing emails. This can be as simple as your employee asking, “Would you like to sign up for service updates and other occasional emails?”

2. Add sign-up forms to your website and booking pages

Your plumbing website is another reliable place to collect email addresses. Add a simple email newsletter sign-up form to your homepage, contact page, and online booking page, where the customer can enter their name and email address.

How to segment your plumbing email list

Email segmentation means dividing your contact list into smaller groups based on shared characteristics, like their neighborhood, type of service they received, or service value.

Instead of sending the same message to everyone, you send emails that are relevant to each group. Segmenting your email list improves open rates, reduces unsubscribes, and increases the chance that customers will book services.

Common ways to segment an email list include:

• Audience: Segment your list by residential or commercial customers. These groups often have different needs and service schedules. Residential emails may focus on maintenance tips and seasonal reminders, while commercial customers may want messages about ongoing service agreements or scheduled maintenance.
• Customer stage: Segment contacts based on their relationship with your business. This may include new plumbing leads who haven’t booked yet, first-time customers, repeat customers, and dormant customers who haven’t scheduled service in a long time.
• Service type: Group customers based on the type of work they received, such as installation, maintenance, or repair. This makes it easier to send follow-up emails that match the type of service they received.
• Plumbing equipment: Segment customers based on the plumbing systems or fixtures involved in the job. Examples include water heaters, sump pumps, toilets, sinks and faucets, showers, or drain and sewer systems. These segments help you send targeted maintenance reminders and service recommendations.
• Service recency: Organize contacts by how recently they booked a job, like within the last six months, in the last year, or more than a year ago. This helps you identify customers who may be due for maintenance or ready for a reminder to schedule service.

You can find these details in your plumbing CRM. When combined, these segments let you send targeted campaigns that feel relevant to the customer and turn one-time service calls into long-term relationships.

How to write plumbing emails that get opened

Your customers are already being bombarded with marketing emails, so your emails need to stand out if you want a customer to open them. Use these email marketing tips for plumbers to create emails that get opened and win new work:

• Write clear, specific subject lines. 47% of recipients decide whether to open an email based on the subject line, so tell the reader what the email is about. Avoid vague or overly promotional language, like “Service announcement” or “SALE SALE SALE.” Focus on maintenance reminders, helpful information, or timely service needs.
• Keep emails short and easy to read. Customers will quickly scan your message. Use short paragraphs and simple language so they can understand the main point right away. Focus on one topic per email instead of trying to cover multiple services at once.
• Personalize your emails. Add a customer’s name or a past service to make the email feel more relevant. For example, you could mention the last time you serviced their water heater or remind them about equipment installed during a previous job.
• Make sure your emails are mobile-friendly. 85% of people read email on their phones at some point during the day. Use a simple layout, large text, and clear spacing so the message is easy to read on a small screen.
• Use one clear call to action. Each email should guide the reader to take one specific next step. For a plumbing business, this often means scheduling service or requesting an inspection. A clear button saying “Request service” or “Book inspection” helps customers take action quickly.
• Maintain consistent branding. Every email should clearly represent your business and include your service business branding. Include your plumbing company name, logo, and contact information each time you send a message. This helps customers recognize your emails and builds trust over time.

Types of email campaigns to send (with templates)

Once you have a customer email list in place, the next step is deciding what to send. It’s best to set up a small set of repeatable campaigns rather than sending occasional one-off emails. 

Below are several common email campaigns for plumbing businesses. We’ve also included a series of email templates for plumbers that you can adapt for your own content marketing.

Welcome email sequence

A welcome email introduces your plumbing business to new contacts, like homeowners who downloaded a guide from your website or customers who recently booked their first service. The goal is to build trust and explain how you can help the customer maintain their plumbing system.

12-month plumbing email calendar

Many plumbing issues follow predictable patterns throughout the year, which makes it easier to schedule relevant reminders and service offers. Planning your emails in advance helps you send messages that match your customers’ seasonal plumbing needs.

How to automate your plumbing email marketing

Automation helps your plumbing business stay in contact with customers without having to manually send every message. Emails can be triggered automatically based on customer actions or service history, saving you time while ensuring customers get timely messages.

These automation tips are a good starting point for most plumbing businesses:

Set up a welcome sequence that runs on autopilot

A welcome sequence is a short series of emails sent automatically when someone joins your email list or becomes a new customer. This could happen after a customer books their first service or subscribes through the email sign-up form on your website.

The first email usually introduces your business and explains the services you provide. A second email can follow a few days later with helpful information, like common plumbing maintenance tips or instructions for scheduling future service.

Once the sequence is set up in your email platform, it runs automatically whenever a new contact is added to your list.

Automate post-service follow-ups and review requests

After a job is completed, the system can automatically send a follow-up message thanking the customer and asking for feedback.

These emails are typically sent 24–48 hours after the service appointment. They often include a short thank-you, a link to leave a review, and contact details in case the customer has questions.

Automating this process helps ensure current customers receive a follow-up. This can increase the number of online reviews your business collects.

In fact, when you use Jobber to send your automated job follow-ups and review requests, you can get twice as many Google reviews as a result.

How to measure email marketing results

Email marketing works best when you track results and make small improvements over time. Monitoring a few specific metrics tells you which emails prompt customers to open, engage with content, and book services.

You can measure the effectiveness of most email campaigns using four metrics. This data is visible in Jobber’s tracking dashboard, as well as most other email marketing platforms:

1. Open rate

This is the percentage of recipients who open your email. It mainly shows how effective your subject line was and whether customers recognize your business.

An open rate of 20–30% is healthy for a plumbing business. If your open rate is lower than that, experiment with clearer subject lines or sending emails at different times.

2. Click-through rate (CTR)

This is the percentage of recipients who click a link inside the email, like a “Schedule service” button or a link to your website. 

A click-through rate of 2–4% usually means the message is relevant and the call to action is clear. If your CTR is lower than that, simplify the email. Focus on one desired action you want the customer to take.

3. Conversion rate

This is the percentage of recipients who complete the desired action after clicking, like booking a service appointment or requesting an estimate. It ties your plumbing company email marketing to revenue and jobs booked.

Aim for an email conversion rate of 2–5%. If your conversion rate is significantly lower, review the booking process and make sure your website encourages visitors to book services with prominent CTAs and a simple request form.

4. Unsubscribe rate

This is the percentage of recipients who choose to stop receiving emails. A small number of unsubscribes is normal—aim for an unsubscribe rate around 0.5%.

Consistently high rates could mean you’re sending emails too often, or the content isn’t relevant to subscribers. Try sending fewer emails or improving your audience segmentation.

Common email marketing mistakes to avoid

Email marketing can be a reliable source of repeat business, as long as you do it right. Avoid these common mistakes to keep your campaigns relevant and effective:

• Sending the same email to everyone: Not every customer has the same needs. You should send different emails to a homeowner who recently installed a water heater versus someone who called for a drain repair. Without segmentation, emails can feel irrelevant, and your customers are more likely to ignore them.
• Emailing too often (or not enough): Too many emails can overwhelm subscribers, while too few can make it easy for them to forget about your business. A consistent schedule, like one or two monthly emails, maintains visibility without becoming intrusive.
• Only sending promotional emails: If every email focuses on discounts or sales, customers may stop paying attention. Balance promos with information that’s useful to subscribers, like plumbing tips and maintenance reminders.
• Not maintaining your email list: Over time, some contacts will change email addresses or stop engaging with your messages. Keeping inactive contacts on your list can reduce overall performance metrics. Go through the list regularly and remove invalid or inactive addresses to help maintain a healthier email list.
• Ignoring mobile optimization: If your message is difficult to read on a small screen, recipients may delete it without reading. Use simple formatting, short paragraphs, and clear buttons so customers can easily read and respond from their mobile device.
