Email and SMS marketing have become essential tools for contractors and service businesses, especially in industries like HVAC, plumbing, and electrical. But too often, these campaigns fall flat. As Josh Crouch, CEO of Relentless Digital, explains, it doesn’t have to be that way. With the right approach, your outreach can fill your schedule, deepen customer loyalty, and drive real revenue while staying welcome in the inbox.
Why Most Contractor Email & SMS Campaigns Fail
Josh breaks the problem down into three “deadly sins” he sees over and over in contractor campaigns:
One and Done
Sending a single, generic blast and giving up when it doesn’t work. Success requires consistency and segmentation. The customer you saw yesterday should never get the same message as one you haven’t seen in three years.
Promotional Puke
Only contacting customers when you have a special offer or deal. Constant pitching devalues your relationship and leads to opt-outs. People want value, not constant sales pressure.
Wrong Message, Wrong Time
Sending the wrong offer to the wrong person at the wrong time. Think furnace tune-ups advertised in the middle of summer, or AC specials landing right after someone replaced their system. Timing and targeting are everything.
Customers Want to Hear From You If You Offer Real Value
A common misconception is that “my customers don’t want to hear from me.” In reality, most customers appreciate communication if it’s relevant, educational, or entertaining. Homeowners often want reminders, answers to simple questions, or tips to protect their investment. They value authenticity and expertise over slick sales tactics.
The research backs this up. In a survey of more than 2,000 consumers, 77% said they want promotional messages by email as long as those messages are relevant, timely, and personalized. The objection was never the email itself. It was the garbage.
Mindset Shift: Be Useful First, Profitable Second
Be useful and entertaining first. Profit follows second. If you consistently nurture your list with value, they’ll be far more receptive when it’s time to make an offer. The contractors who send eleven helpful messages and one offer book more work than the ones who send twelve offers. Goodwill is the asset. The offer just cashes it in.
What “Relevant” Actually Looks Like to a Homeowner
Relevance isn’t a feeling, it’s a data point. A homeowner with an eight-year-old system wants to know what fails next and what it costs. Someone who just had a repair wants to know what to watch for. A customer heading into their first winter in a new house wants to know what to do before the first hard freeze. Same list, three completely different messages, and all three are welcome because they match where that person actually is.
The Three Email Campaigns Every Contractor Needs
Josh runs the same three campaigns for contractors in every trade, every season:
Seasonal Prep Campaigns
Launch 6-8 weeks before your peak season. These get customers ready for extreme weather or relevant events (A/C in spring, furnaces in fall, storm prep for roofing, etc.). Segment based on service dates, equipment age, and climate trends.
Lifecycle Education
Share content that helps people get more out of what they own. This can be care reminders, troubleshooting tips, or “what to expect next” guides relevant to the age of their equipment or home.
Win-Back Campaigns
Target dormant customers who haven’t been serviced in over a year. Use re-engagement subject lines (“Did we screw up?”) and offer low-barrier value inspections or checkups to get them back on your schedule.
Email vs. SMS: When to Use Each Channel
- Email is best for nurturing, stories, and detailed education. People tend to read more slowly and digest longer-form content here.
- SMS is for quick, personal, booking-focused messages. Keep it brief, friendly, and direct: “Hey Sarah, it’s Mike from Comfort Air. You’re due for your AC checkup ($49). Want a spot before the rush?”
Combine both channels for maximum effect: educate via email, then prompt with SMS.
Data, Timing, and Personalization: The Golden Trio
Everything in this article depends on knowing something about the person you’re messaging. That information already exists in your system. Most contractors just never pull it out.
- Start with the data you already have. Pull names, last service dates, equipment age, and service type out of your CRM. Three fields are enough to build a real segment. Equipment age alone tells you who’s due for maintenance and who’s close to a replacement conversation.
- Personalize past the first name. Anyone can merge a name into a subject line. Reference the actual visit, name the tech who was there, and mention the specific unit. “Mike was out in April for your condenser” lands differently than “Hi Sarah.”
- Send when the message is already true. After a storm, six weeks before peak season, or the week a system crosses the age where failures start. The offer doesn’t have to be clever if the timing makes it obvious.
The Secret Sauce: Storytelling and Simple Language
The best messages use stories. Pull real examples from service calls, add personalized anecdotes, and explain things at a 6th to 7th grade reading level. Don’t rely on technical jargon or AI-generated content alone; harvest technician notes and real customer experiences for authenticity.
Action Plan: How to Start (and Succeed)
- Segment Your List: Break down customers by last service date, equipment age, and service type.
- Pick One Campaign: Start with a single, timely campaign instead of trying to do everything at once.
- Send to Yourself First: Test for deliverability, appearance on mobile, and clarity.
- Measure and Adjust: Track opens, replies, bookings, and revenue. Split test subject lines and offers. Refine based on results.
- Repeat: Gradually expand to include multiple nurture, seasonal, and win-back campaigns.
Pro Tips for Better Email and SMS Results
- Don’t get discouraged by unsubscribes. Every one leaves you with a more targeted list.
- Avoid generic discounts (e.g., “10% off any repair”); make offers relevant to real needs.
- Ask for reviews after every service call. Plenty of happy customers have never left one, and review volume affects your search rankings.
- Warm up new domains gradually if you change your sending setup to avoid spam filters.
- Get consent before you send. Email and texting are regulated differently. For promotional SMS, federal rules require written consent before you send promotional texts to a customer’s mobile number, and a service call alone doesn’t count. On the email side, include a working unsubscribe link in every email and honor opt-outs quickly. Build consent capture into your intake forms and service agreements now, not after a complaint.
Building an Email and SMS Program That Fills Your Schedule
Email and SMS marketing work when you do the groundwork. Stop sending garbage. Segment, personalize, educate, and time your outreach thoughtfully. By putting your customer’s needs first, your campaigns will get replies, bookings, and build loyalty in even the most competitive markets.
