Aphing Marie-JosephSocial media users are hesitant. Ad traffic is rented. Your email list is the only marketing asset you truly own—and that distinction matters more than most small business owners realize until an algorithm changes or ad costs rise.
The numbers confirm it. Email offers an average return on investment of 36 $ for every dollar spent—the highest of any digital marketing channel, far surpassing paid search, social media advertising, and display ads. And yet, 43 % of small businesses have 500 email subscribers or fewer, and with a list of that size, only 20 % consider their email strategy effective. The channel works—the list just needs to be long enough and healthy enough to work for you.
If you're starting from scratch, here's how to create an email list that will really help your business grow.
Start with something worth signing up for
No one gives out their email address for nothing. The first thing you need is a lead magnet: a specific, useful resource that solves a real problem for your target customer in exchange for their contact information.
The key word here is “specific.” Generic e-books and vague newsletters don’t convert. Specific, immediately useful resources do: templates, checklists, calculators, and short guides consistently outperform longer content because they provide value the moment someone downloads them.
Here are a few lead magnet formats that work well for small businesses:
- A helpful checklist for you («10-Point Checklist Before Hiring a Contractor»)
- A discount or first-time purchase offer (common in retail and e-commerce)
- A free tool or calculator («Estimate the cost of replacing your roof»)
- A short course via email or a practical guide
- Access to a resource library or a template pack
The goal is to attract people who are likely to become customers—not just those looking for freebies. A well-chosen lead magnet does both: it offers immediate value and signals to the right people that you know what you’re talking about.
Place your registration forms where people actually are
A great lead magnet is useless if no one sees it. Once you have your offer, you need to place sign-up opportunities in the right places—on your website and beyond.
On your website, the pages with the highest conversion rates are usually:
- Home Page — above the fold or in a sticky header
- Blog Posts – particularly as an update to the online content («Download the checklist that accompanies this article»)
- Exit-Intent Popups — triggered when a visitor is about to leave
- Dedicated Landing Page — a single-purpose page with one goal: to collect an email address
Pair your main magnet with a well-timed pop-up or a contact form embedded on your most-visited pages for maximum impact. Timing and placement are key: a pop-up that triggers after 20 seconds or based on scroll depth converts better than one that triggers the moment someone lands on the page.
Don't neglect your existing digital touchpoints either. Your email signature, yourYour Google Business Profile and your payment confirmation page are both places where you’re already in front of warm leads who haven’t subscribed yet.
Use social media to grow your list
Social media and email aren’t competing channels—they work best together. Effective tactics include adding a link to the landing page for your main lead magnet in every Instagram, TikTok, LinkedIn, and X bio; promoting subscriber-only content in posts and stories; running a short social media series that ends with «Get the complete guide via email»; and hosting a live session with the replay available to email subscribers.
The wording matters. «Sign up for our newsletter» is a weak request. «Get (specific resource) for free» is a stronger call to action. Make your mailing list feel like a VIP section—because that’s exactly what it should be. Offer subscribers something they can’t get just by following you on social media.
Ask in person (seriously)
For small local businesses, in-person outreach is underutilized and surprisingly effective. If you have a physical location, a reception desk, or a service appointment process, you have the opportunity to collect email addresses that most businesses leave on the table.
Some practical ways to collect email addresses in person:
- Sign up on a tablet or on paper at the cash register or at the front desk
- A QR code on a place card, receipt, or package that links to your registration page
- Ask verbally at the end of a customer service interaction («May I have your email address so we can send you our monthly tips and offers?»)
These subscribers tend to be highly engaged because they already have a genuine relationship with your company. They aren't cold leads—they're customers.
Give people a reason to stay subscribed
Building a list is only half the battle. The average growth rate for email lists was just 4 % in 2024, down from 6 % in 2023. That same year, approximately 16 % of subscribers were lost due to a combination of unsubscribes and bounces, meaning that many companies are essentially treading water. If you’re gaining subscribers on one hand but losing them on the other because your emails aren’t worth opening, the list never really grows.
The solution is simpler than it seems: send emails that people actually want to read. That means a consistent schedule (once a month rather than sporadic bursts), subject lines that give people a reason to open the email, useful content rather than purely promotional material, and occasional exclusive offers or early access that reward subscribers for sticking around.
Generating Automated Emails 320 % in additional revenue Non-automated emails—and for small businesses, a simple welcome sequence (two or three emails that deliver the main lead magnet, introduce the company, and extend an offer)—are the most effective form of automation you can implement. Most email platforms make this easy, even without a developer.
Keep your list clean
A large list and a healthy list are not the same thing. Deliverability (whether your emails actually reach the inbox) is largely determined by the level of engagement among your subscribers. Only 35 % of marketers Regularly remove unengaged subscribers, as this means that the majority of them are quietly driving down their own open rates and inbox placement without even realizing it.
About every six months, launch a re-engagement campaign targeting your inactive subscribers. Give them a reason to stay: a special offer, a useful resource, or a simple «Still interested?” email. Those who don’t respond are removed. It may seem counterintuitive to shrink your list, but a smaller list of engaged subscribers is better than a large list of people who never open your emails.
Choose the right tools
You don't need an expensive platform to get started. Most email marketing tools offer free plans that are more than enough for small businesses with fewer than a few hundred subscribers. Popular options includeMailchimp,Constant contact,Klaviyo (which is particularly powerful for e-commerce), andKit (formerly ConvertKit, a favorite among service companies and creators).
What you’re looking for to start with: an easy way to create sign-up forms, a simple automation builder for your welcome sequence, and clear analytics that show open and click-through rates. You don’t need all the features right from day one—you just need to start sending emails and learn what resonates with your audience.
Building a list takes time—but get started anyway
Small businesses with more than 500 engaged subscribers more than double the likelihood that their email marketing will be effective—and this figure is achievable for almost any business. But it doesn’t happen on its own. It happens because someone placed a lead magnet on the website, surveyed customers in person, promoted sign-ups on social media, and continued to appear regularly in the inbox.
Email marketing rewards patience and consistency more than almost any other channel. The list you build this year will pay dividends for years to come—and unlike your social media followers, it will stay with you no matter what changes occur on any platform.
