Somewhere in your business there is a list of people who hired you and were glad they did. It might sit in your invoicing software, a spreadsheet, or a drawer of old work orders. Most of those people haven’t heard from you since the invoice.
Email is the cheapest way to change that. Our position on email marketing tips for small businesses is simple: five habits cover most of what a local business needs. Write like a neighbor, send to the right group, keep it short, show your customers’ work, and automate the routine messages. Everything else is polish.
Does email still work for a small business?
For most, yes, with one condition. Is the list made of people who already know you? Email doesn’t introduce you to strangers. It reminds people who trust you that you exist, and it costs far less than most advertising. The list is also yours, so no platform decides how many of your own customers see a message.
Owners say much the same. In Constant Contact’s 2025 Small Business Now research, a survey of 2,500 small business decision-makers in the US, Canada, the UK and Australia, 44% named email their most effective marketing channel. Constant Contact sells email software, and the survey records what owners believe is working, not measured sales.
On return, Litmus reported in 2025 that 35% of the marketers it surveyed see between $10 and $36 back for every dollar spent. That was nearly 500 marketing professionals worldwide, and it counts only people who measure their return. Read it as a sign that email tends to pay its way. It isn’t a number to expect.
How well it works for you depends on how often a customer needs you. A roofer may see the same homeowner once in many years, so email is mostly about being remembered and recommended. A pool company sees its customers every season, so email can carry the opening and closing reminders. Same tool, very different emails.
Five email marketing tips for small businesses
Tip 1: Write like a neighbor
Think about the emails you open yourself. They come from someone you know, or they tell you something you can use. For a local business, useful means local and specific: a seasonal reminder that fits this weather, a short answer to a question you’ve heard several times this month, or news about a town event you’re part of.
One example of how you actually work says more than “quality and care.” If you’re starting from nothing, our guide on how to start a small business newsletter covers the first steps.
Tip 2: Send the right message to the right group
A healthy list is made of people who agreed to hear from you: customers, people who asked for an estimate, people who signed up on your website. Split it into a few groups. Past customers, people who got an estimate and didn’t go ahead, and customers on a maintenance plan each need different news.
Say a pool company in Richboro sends every contact the same “time to open your pool” note. The family whose pool went in last month has nothing to open yet. The homeowner who asked for a quote in March and went quiet needs something else entirely. A first name in the greeting is nice. Getting the group right matters more.
Tip 3: Keep it short and recognizably yours
Your customers read on phones, between other things. One topic and one next step is usually enough. Do you want them to book, reply, call, or leave a review? Pick one.
Use the same logo, colors and tone every time, and send from a real name at the business. If the email sounds like the person who showed up at the house, it’s doing its job.
Tip 4: Put your customers in the spotlight
A photo of a recent project, shared with the customer’s permission, tells readers more than anything you could say about yourself. So does a review that shows how you handled a problem. Either one also gives past customers an easy reason to reply or pass the email along.
Tip 5: Automate the routine emails
In the same Constant Contact survey, 42% of small businesses said they have less than an hour a day for marketing. So the emails that should go out every time are the ones that get skipped when the week fills up. That means the welcome note, the thank-you after a job with a review request, and the follow-up a few days after an estimate.
Imagine a pest control company in Skippack that sends a reminder before each customer’s next treatment is due. Nobody there has to remember to write it. Marketing automation, in plain terms, is software that sends a message you wrote in advance when a condition you chose is met. You still have the conversations. The system just remembers who needs one.
What email can’t do, and the rules that apply
Email works on the people already on your list. It won’t produce a set amount of work by a set date. It builds slowly, and a monthly email you keep sending does more than a weekly one you abandon by March.
There are also rules. The Federal Trade Commission’s CAN-SPAM compliance guide says marketing email must include your valid physical postal address and a clear way to opt out. You must honor an opt-out request within 10 business days, and you can’t use deceptive subject lines. It also says the law makes no exception for business-to-business email.
A reputable email platform handles most of the mechanics, but the responsibility stays with the sender. What you can prepare is an address to print in the footer and a record of who has opted out. If you’re unsure whether a particular message counts as marketing, that’s a question for a lawyer.
Your part is real, too. We can plan, write, design and send as part of our email marketing work, but we can’t know about the job you finished last week unless you tell us. Photos, news and an up-to-date list come from you. So does the most useful feedback, which is whether an email led to work you wanted. Opens and clicks are useful signals, and we explain how to read them in our article on email marketing metrics.
Start with the list you already have
This week, export the customers from your invoicing software with their email addresses. Then mark the ones you’d gladly work for again. It takes about twenty minutes and costs nothing, and it tells you whether you have a list or only a pile of names.
Send us the count, what you’ve emailed them so far, and what you’d like them to do next, whether that’s book, refer or review. We’ll tell you what we’d send first and why. Your first consultation is free, and you can get in touch with us here.
