Email marketing for plumbers and HVAC companies lets you stay top-of-mind with customers, follow up after service calls, and book more repeat business. GoHighLevel's built-in email platform handles everything from one-off campaigns to automated drip sequences, so you don't need separate tools like Mailchimp or ConvertKit.
Most HVAC and plumbing businesses lose tons of revenue because they never follow up. A customer gets their furnace fixed in January, loves the work, but forgets your name by October when they need duct cleaning. Email sequences solve this by keeping you visible year-round, automating review requests, and nurturing leads who aren't ready to book yet.
What is Email Marketing & Sequences in GoHighLevel
GoHighLevel's email marketing is a complete email platform built into your CRM. You create campaigns, build automated sequences, segment your contact list with smart filters, and track who opens and clicks your emails. Everything happens inside GHL, so no juggling multiple tools or monthly fees for email services.
The platform includes a drag-and-drop email builder with templates, automated workflows that send emails based on triggers, and smart lists that segment your contacts. You can send one-off newsletters to your entire list or set up complex nurture sequences that send different emails based on what customers do.
For service businesses like HVAC and plumbing, this means you can automatically follow up after installations, send seasonal reminders for maintenance, and nurture leads over months until they're ready to book. The system tracks everything, so you see which emails get opened and which customers are engaging with your content.
Unlike standalone email tools, GHL email integrates directly with your contact records. When someone books an appointment from an email, you see their entire history. When they call, you know exactly what emails they've received. This context makes every interaction more personal and effective.
How to Set Up Your Email Sending Domain in GoHighLevel
Before sending any emails, you need to set up your sending domain for better deliverability. This involves configuring DNS records so email providers trust your messages and don't flag them as spam.
Step 1: Go to Settings > Email Services in your GHL account. Click "Add Domain" and enter your website domain (like yourcompany.com).
Step 2: GHL generates three DNS records: SPF, DKIM, and DMARC. Copy these records exactly as shown. Don't modify the formatting or spacing.
Step 3: Log into your domain registrar (GoDaddy, Namecheap, etc.) and add these records to your DNS settings. Most registrars have a DNS management section where you can add TXT records.
Step 4: Wait 24-48 hours for DNS propagation. GHL will verify the records automatically and show a green checkmark when everything's working.
Don't skip this step. Sending emails without proper domain setup means your messages will land in spam folders or get blocked entirely. i've seen businesses wonder why their emails aren't getting opened, and it's usually because they skipped domain authentication.
Once your domain is verified, you can send from addresses like info@yourcompany.com or service@yourcompany.com. This looks more professional than Gmail addresses and improves your delivery rates significantly.
How to Create Your First Email Campaign
Creating an email campaign in GHL takes about 10 minutes once you know the process. You can send one-off newsletters, promotional emails, or seasonal reminders to your entire list or specific segments.
Step 1: Navigate to Marketing > Emails in your GHL dashboard. Click "Create Campaign" to start a new email.
Step 2: Choose your sender information. Use your verified domain email as the "from" address and write a clear "from name" like "Mike from ABC Plumbing" so recipients recognize you.
Step 3: Write your subject line. Keep it under 40 characters for better mobile open rates. "Your furnace filter reminder" works better than "Important seasonal maintenance information for your HVAC system."
Step 4: Use the drag-and-drop builder to design your email. Start with a template or build from scratch. Add your logo, write your message, and include a clear call-to-action button.
Step 5: Select your audience using Smart Lists. You can send to everyone or create segments like "Customers who had AC service in the last 6 months" or "Leads who requested quotes but didn't book."
The email builder includes pre-made templates for service businesses, but i recommend customizing them with your branding and specific services. Generic templates scream "marketing email" while personalized designs feel more like communication from a local business.
Always preview your email on both desktop and mobile before sending. About 60% of emails get opened on phones, so your message needs to look good on small screens. GHL's builder shows you exactly how it'll appear on different devices.
Building Automated Email Sequences for Service Follow-up
Automated email sequences let you follow up with customers without manual work. Set them up once, and they run forever, sending the right message at the right time based on triggers like service completion or lead source.
The most effective sequences for HVAC and plumbing businesses focus on service follow-up, maintenance reminders, and lead nurturing. A customer who gets their water heater replaced should receive different emails than someone who just requested a quote for bathroom remodeling.
Step 1: Go to Marketing > Workflows and click "Create Workflow." Choose "Start from Scratch" to build a custom sequence.
Step 2: Set your trigger. Common triggers include "Contact tagged as 'Service Complete'" or "Opportunity stage changed to 'Won'" or "Form submitted on website."
Step 3: Add a delay action. Wait 1 day after service completion before sending your first follow-up email. This gives customers time to experience your work.
Step 4: Add an email action. Create your first follow-up email asking about their satisfaction and requesting a review. Keep it short and friendly.
Step 5: Add another delay (7 days) and a second email about preventive maintenance or seasonal tips related to the service they received.
Step 6: Continue building the sequence with valuable content, not just sales pitches. Share maintenance tips, seasonal reminders, or special offers for existing customers.
A typical service follow-up sequence might look like: Day 1 - satisfaction check and review request, Day 7 - maintenance tips related to their service, Day 30 - seasonal reminder about related services, Day 90 - special offer for existing customers. Each email provides value while keeping your business top-of-mind.
Don't make every email a sales pitch. Mix helpful content with promotional messages. An email about "5 signs your water heater needs attention" provides value and positions you as the expert they'll call when problems arise.
How to Segment Your Email List for Better Results
Sending the same email to everyone on your list kills engagement and wastes opportunities. Smart segmentation means sending furnace maintenance tips to HVAC customers and pipe care advice to plumbing customers.
GHL's Smart Lists let you create segments based on tags, services purchased, location, lead source, or any custom field. The key is thinking like your customers and grouping them by what they actually care about.
Start with these basic segments for HVAC and plumbing businesses:
- Service type: HVAC customers vs. plumbing customers vs. both
- Customer status: New leads, current customers, past customers
- Property type: Residential vs. commercial clients
- Seasonal needs: Customers with pools, fireplaces, or outdoor equipment
- Service history: Recent installations, maintenance customers, emergency calls
To create a Smart List, go to Contacts > Smart Lists and click "Create Smart List." Set your criteria like "Tag contains 'HVAC'" AND "Last activity within 90 days" AND "City equals 'Denver'." This creates a list of recent HVAC customers in your service area.
More advanced segments might include customers who spent over $5,000 (premium prospects), customers who haven't been serviced in over a year (reactivation targets), or leads who opened your last three emails but didn't book (highly engaged prospects).
Start simple with 3-4 basic segments, then get more sophisticated over time. Complex segmentation is powerful, but it's better to send good emails to broad segments than perfect emails to overly narrow ones.
Essential Email Templates for HVAC & Plumbing Companies
Having proven email templates saves hours of writing and ensures you cover all the important touchpoints with customers. These templates work across different types of service businesses but should be customized with your specific services and local details.
Service completion follow-up email: "Hi [First Name], thanks for choosing [Company] for your recent [Service Type]. How did everything go? If you're happy with the work, would you mind leaving us a quick review? [Review Link]. If you have any questions about your new [Equipment/Repair], just reply to this email."
Seasonal maintenance reminder: "Hi [First Name], it's that time of year again. Your [HVAC System/Water Heater/Plumbing] should be checked before [Season]. We serviced your system last [Month/Year], and annual maintenance keeps everything running efficiently. Reply to schedule your maintenance visit."
Lead nurturing for non-urgent services: "Hi [First Name], you contacted us about [Service]. We know these projects take time to plan. Here are 3 things to consider: [Tip 1], [Tip 2], [Tip 3]. When you're ready to move forward, just reply or call [Phone]. No pressure, we're here when you need us."
Emergency service follow-up: "Hi [First Name], emergency repairs are stressful, but you handled it perfectly by calling us. Your [System] is working properly now. Keep our number handy: [Phone]. For after-hours emergencies, we're available 24/7. Thanks for trusting [Company] with your urgent repair."
Each template should include your company branding, clear next steps, and multiple ways to contact you. Don't make customers hunt for your phone number or wonder what they should do next. i covered more about integrating these emails with your overall automation strategy in my guide to GHL automation for plumbers and HVAC companies.
Measuring and Improving Your Email Marketing Performance
Tracking email performance shows you what's working and what needs improvement. GHL's analytics tell you exactly who's engaging with your emails and which messages drive the most bookings.
The most important metrics for service businesses are open rates, click rates, and conversion to bookings. Industry average open rates for small businesses are around 20-25%, but you should aim higher with a local, targeted list. Click rates of 3-5% are typical, but service businesses often see higher rates because your emails solve immediate problems.
Go to Marketing > Emails > Reports to see detailed performance data. You'll see:
- Open rates by email: Which subject lines get attention
- Click rates: Which calls-to-action work best
- Unsubscribe rates: If you're sending too often or irrelevant content
- Bounce rates: How many emails don't get delivered
- Revenue tracking: Which emails lead to booked appointments
Test different send times and subject lines. B2B services often see better open rates on weekdays 9-11 AM, while residential services might perform better evenings and weekends when homeowners are thinking about house projects.
If your open rates are low (under 15%), your subject lines might be too generic or your sender name isn't recognizable. If people open but don't click, your email content isn't compelling or your call-to-action isn't clear. If they click but don't book, the problem might be your booking process or pricing, not your email.
Set up conversion tracking by connecting your email campaigns to GHL opportunities. When someone books from an email link, you'll see exactly which email drove the sale. This data helps you double down on what works and eliminate what doesn't.

look, i was skeptical about email automation too... until i realized i was literally watching $500 jobs walk out my door and forget i existed. the platform i use for my plumber clients automates the whole follow-up sequence - from review requests to seasonal reminders - and honestly, it's the difference between feast or famine months.
