Email Marketing for Small Business: Is It Still Worth It?

Every few years, someone declares email marketing dead. Every few years, the data proves them wrong.

Email is not flashy. It doesn't trend. But for small businesses that want a reliable, measurable way to stay in front of customers and drive repeat revenue, it's hard to beat. Here's what you need to know before deciding whether to invest in it.

Why Email Still Works

There are roughly 4.5 billion email users worldwide, a number that keeps growing. More importantly, when someone gives you their email address, they've opted in. That's a fundamentally different relationship than someone who scrolled past your ad.

According to Litmus's 2024 State of Email report, email marketing delivers an average return of $36 for every $1 spent. Compare that with paid social or Google Ads, where $1 typically returns $2 to $4 for most small businesses. Email's ROI advantage comes from one key factor: you own the list. There's no algorithm deciding who sees your content and no cost-per-send once you have subscribers.

Average open rates across campaigns run around 43% based on MailerLite's 2025 benchmarks across 3.6 million campaigns. Compare that to organic Facebook reach for business pages, which typically falls below 5%. Email reaches your audience far more consistently.

What You Actually Need to Start

You don't need a sophisticated setup to begin. Three things are enough:

An email platform. Mailchimp, MailerLite, Klaviyo (for e-commerce), or Kit all work well. Most have free plans up to 500 to 1,000 subscribers.
A way to collect addresses. A simple sign-up form on your website is enough. A lead magnet, like a useful checklist or a small discount, helps grow the list faster but isn't required to start.
Something worth sending. Monthly is enough for most businesses. A helpful tip, a business update, a relevant offer. If you can write a sentence, you can write an email.

What you don't need on day one: a designer, a copywriter, or a complex automation sequence. Those things add value later. The most important step is starting with something simple and sending it consistently.

What to Actually Send

The most common reason small businesses stop emailing their list is running out of ideas. A simple framework solves that:

Monthly newsletter: One useful piece of information for your customers. A seasonal tip, a common question answered, a behind-the-scenes update. Keep it short.
Promotional emails: Tied to a real offer or event. A seasonal sale, a new service launch, a time-limited discount. No more than once a month or they lose their impact.
Re-engagement emails: For customers who haven't bought or booked in 6+ months. A simple "we miss you" with a small incentive often wins back a meaningful percentage.
Welcome email: Sent automatically when someone signs up. Thank them, set expectations, include your best content or offer. This single email typically has the highest open rate of anything you'll send.

Building Your List From Zero

Start with what you have. Every business has a starting point:

Add a sign-up form to your website's home page, footer, and contact page
Ask existing customers directly if they'd like to hear from you
Include a sign-up link in your email signature
Offer something worth subscribing for: a discount, a useful guide, early access to promotions

A list of 200 engaged customers who know your business beats 5,000 cold contacts every time. Focus on quality over quantity, especially early on. Our email marketing service includes list-building strategy as part of the setup.

What Realistic Results Look Like

For a small business sending to a warm list of 300 to 1,000 subscribers, here's what to expect in the first 6 months:

Open rates of 30 to 50% on a well-maintained list
Click rates of 2 to 5% depending on the offer
Direct revenue from promotional emails, trackable through your platform
Steady list growth as your sign-up form gets more traffic

Email compounds over time. A business sending a consistent monthly email for two years has a real asset. One that hasn't started yet is starting from zero.

Frequently Asked Questions

How often should I send emails?

Monthly is the minimum for most small businesses. Weekly works if you have genuinely useful content at that frequency. Too infrequent and subscribers forget who you are. Too often without value and they unsubscribe. Find a rhythm you can sustain consistently.

What's a good open rate for a small business?

For a warm, permission-based list, 30 to 45% is healthy. Below 20% usually means your subject lines need work, your list has gone stale, or you're not targeting properly. Above 50% is excellent and typically happens with highly engaged niche audiences.

Do I need to worry about CASL in Canada?

Yes. Canada's Anti-Spam Legislation requires consent before sending commercial emails to Canadian recipients. Express consent means someone explicitly signed up. Implied consent covers existing business relationships. When in doubt, use explicit opt-in and keep records of when and how people joined your list.
