You finish a job, the client pays, you pack up your tools and drive off. And then you never hear from them again, until maybe three years later when they need someone and can’t remember your name.
Here’s the thing most contractors get wrong: that client who just paid you? They’re your cheapest and easiest source of future work. One well-timed and well-written email can bring them back faster than any cold call or Google ad ever could. Because they already know you, they already trust you, and they’re already happy with your work. You’re not selling yourself, you’re just reminding them you exist.
Because they’ve already bought from you. They’ve already made the decision to trust you with their home or business. That trust is gold.
Think about it. A new lead finds you on Google, visits your website, reads your reviews, calls you for a quote, compares you to three other contractors, and then maybe hires you. That’s a lot of friction.
A past customer? They already know your work is solid. They already know you show up on time and clean up after yourself. All they need is a gentle nudge reminding them you’re still around.
And here’s the kicker: past customers are more likely to refer you to their friends and family too. One email can trigger not just a repeat job, but three more from their neighbour, their brother, or their mate from work.
Domain Boost puts it perfectly: “Most contractors focus on getting new clients but forget about the goldmine sitting in their inbox.” That goldmine is your past customer list.
Not a generic newsletter. Not spam. Not something that looks like it was sent to a thousand other people.
What works is personal, timely, and useful communication.
Here are a few examples that actually get replies:
“Hey Dave, it’s that time of year again – before summer hits, we’re booking air conditioning tune-ups. You mentioned last year your system was struggling a bit. Want us to come take a look before the heatwave
“Hi Sarah, just checking in – we installed your deck about 18 months ago. Everything holding up okay? We’re offering a free inspection for past clients this month.”
“Happy one-year anniversary of your new bathroom! We hope you’re still loving it. If anything’s come up or you’re thinking about the next project, we’d love to help.”
The key is relevance. You’re not selling, you’re offering value. And when the timing is right, they’ll book.
This is where it gets clever. You don’t have to remember to send these emails. You don’t have to sit down and write them every month. An automated email system does the heavy lifting for you.
Domain Boost sets up systems that run in the background, sending the right message to the right person at the right time. Here’s what that looks like:
Welcome sequences: When a new lead comes in, they get a series of emails introducing your business, showing your best work, and making it easy to book.
Monthly updates: Past clients get a monthly email with helpful tips, seasonal reminders, or just a quick “we’re still here” message.
Seasonal promotions: Before summer, winter, or any busy season, your system automatically sends relevant offers to the right segments of your list.
Re-engagement campaigns: If someone hasn’t booked in a while, they get a gentle nudge asking if they need anything.
“The automation system they built keeps everything running in the background. We get leads every week without lifting a finger,” says one Domain Boost client. That’s the power of automation, it works while you’re on the tools.

One client puts it simply: “Every time they send a campaign, we get new quotes and repeat clients. It’s simple and effective.”
Method | Cost | Effort | How it works |
Cold calling | Low | High | You chase leads, most say no |
Google Ads | High | Medium | You pay for every click |
SEO | Medium | High | Takes months to rank |
Email to past clients | Low | Low (once set up) | Warm leads who already trust you |
Email marketing to past clients consistently delivers the highest return on investment because you’re not chasing strangers, you’re reminding people who already know you’re good.
Domain Boost has worked with over 180 trade businesses across Canada. Here’s what some of them say:
“Domain Boost helped me generate consistent leads through my website. Their strategies are practical and effective, and the support team always goes the extra mile.”
“We never thought email would work for trades, but Domain Boost proved us wrong. Every time they send a campaign, we get new quotes and repeat clients.”
“Every email looks amazing, clean design, clear message, and it fits our brand perfectly. Our clients actually reply and book directly from the email.”
Look, you’re already doing the hard work; showing up, doing quality work, keeping clients happy. But if you’re not staying in touch with those clients after the job’s done, you’re leaving money on the table. They want to hire you again. They just need a reminder.
At Domain Boost, we specialise in helping contractors across Canada turn past customers into repeat clients. We build email marketing systems that work automatically, sending the right message at the right time, so you never miss an opportunity. From strategy to copy to design to automation, we handle everything.
We’ve helped over 180 trade businesses grow with data-driven email campaigns, targeted automation, and trade-focused content that actually gets replies and bookings.

Email marketing is significantly cheaper. Email generates between $36 and $42 for every dollar spent. By comparison, Google Ads returns about $8 per dollar, and social media ads return $2 to $5. The cost to send an email to a past customer is only about $0.05 to $0.15, while a lead from Google Local Services Ads costs around $60.50 on average.
It’s very real. One reactivation campaign sent to 1,000 past customers can generate $4,000 to $12,000 in booked jobs. If you send that campaign quarterly, you could be looking at $16,000 to $48,000 in annual revenue. One HVAC contractor generated $60,000 from a single “we miss you” campaign sent to 1,200 dormant customers
Yes, and that’s the whole point. Automated email workflows generate 30 times higher returns than one-off campaigns. Once set up, they run in the background—sending instant responses to new leads, following up on estimates, and sending seasonal reminders. Without automation, only about 15% of leads get follow-up after day three. Automation ensures you stay in touch with every lead and past customer without manual effort.
In Canada, you need to comply with CASL (Canada’s Anti-Spam Law). In the US, it’s CAN-SPAM. Every email must include a clear way for recipients to unsubscribe, and you should only email people who have given proper consent. A reputable email marketing provider will build compliance into every campaign from the start.
Look at open rates (the construction industry average is 21.7% to 39.14%), click-through rates (1-3% is typical), and most importantly, how many bookings or calls actually come from each campaign. A strong email program typically delivers 300-500% ROI.
Sending generic blasts to everyone on their list with no relevance or personalization. Another big mistake is only emailing when business is slow, which signals desperation and performs poorly. The most successful contractors send consistent, helpful emails monthly, not just when they need work.
