Email marketing costs $0.01-0.05 per contact per month - making it the cheapest marketing channel available to contractors. A list of 2,000 past customers costs $20-100/month to email, and a single HVAC tune-up booking from that email pays for the entire year.
Most contractors collect customer emails but never use them. That's revenue sitting in your database.
The 4 Emails Every Contractor Should Send
1. Post-Job Follow-Up (within 24 hours)
Thank the customer, ask for a review, and offer a referral incentive. Post-job follow-up emails within 24 hours generate 3x more Google reviews than asking later.
2. Seasonal Maintenance Reminders (4x per year)
"Time to schedule your spring AC tune-up" or "Fall furnace inspection before the cold hits." Seasonal maintenance reminder emails generate $15-25 in revenue per email sent based on Mailchimp benchmarks for home service businesses.
3. Monthly Newsletter (12x per year)
Tips, seasonal advice, and a soft promotion. Keeps your name in front of customers so they call you instead of Googling "plumber near me" next time.
Contractors who send monthly emails see 25-35% higher customer retention rates compared to those who only communicate during service calls.
4. Estimate Follow-Up (3-day sequence)
If a customer received an estimate but hasn't booked, send a reminder at 48 hours, 5 days, and 14 days.

What to Write
Keep it simple. AI tools like ChatGPT can draft your emails in minutes.
Effective email formula:
1. One useful tip or seasonal reminder
2. One customer story or recent project
3. One clear call-to-action (schedule service, refer a friend, leave a review)
Keep emails under 200 words. Your customers are busy homeowners, not blog readers.

Get StartedBuilding Your List
Every customer touchpoint is a list-building opportunity:
- Job completion forms
- Estimate submissions
- Website contact forms
- Phone calls (ask for email during booking)
A plumber on ContractorTalk grew their email list from 200 to 2,400 in one year simply by having the CSR ask for an email address during every booking call.
Worked Example: Email Marketing ROI
2,000-contact list on Mailchimp at $30/month. Send 4 seasonal maintenance emails/year. At $15-25 revenue per email sent (Mailchimp benchmark), 4 emails × 2,000 contacts × $20 average = $160,000 in attributable revenue. Even at 1/10th that conversion rate: $16,000/year from $360 in email costs. ROI: 44x. Monthly newsletter adds another 5-10% in retention revenue.
What Not to Do
- Don't buy email lists. Purchased lists have 0.1% open rates and get you flagged as spam. Build your list from actual customers and leads.
- Don't send walls of text. Keep emails under 200 words. One tip, one CTA, one reason to open. Your customers are busy homeowners.
- Don't email without a CTA. Every email needs one clear action: schedule service, leave a review, refer a friend. No action = no revenue.
- Don't skip the subject line. 47% of recipients decide to open based on subject line alone (HubSpot data). "Time for your spring AC tune-up" beats "March Newsletter."
- Don't forget mobile formatting. 60%+ of emails are opened on phones. If your email doesn't look good on a 5-inch screen, it gets deleted.
