Email marketing: the most underrated channel for small businesses

Social reach depends on an algorithm. Ads stop the moment you stop paying. Email is different: a direct line to people who already know you, that you own outright. That's why, year after year, email remains one of the highest-returning channels in marketing — especially for small businesses.

Why email punches above its weight

• You own the list. Platforms change their rules; your list is yours forever.
• Warm audience. These people bought from you or asked to hear from you — the hardest part is already done.
• Tiny cost. Sending email is nearly free, so even modest results mean strong returns.
• Perfect for repeat business. For most small firms, the cheapest new customer is a previous one. Email is how you stay remembered.

Building a list (the right way)

Never buy lists — it's ineffective and falls foul of UK GDPR. Instead, grow your own: ask at the point of sale, add a simple signup to your website with a reason to join (a discount, a useful guide, early access), and always make it a genuine opt-in.

What to send (without being annoying)

The test for every email: would a customer be glad they opened this? Useful ideas that clear the bar: seasonal tips related to what you do, genuine offers, new products or services, reminders for things customers forget (services, renewals, bookings), and the occasional behind-the-scenes story. One or two emails a month, consistently, beats a burst of five followed by silence.

The basics that make it work

Write subject lines like a human, not a billboard. Send from a real name. Make emails mobile-friendly and brief. Always include one clear action — book, browse, reply. And watch your numbers: opens tell you about subject lines, clicks tell you about content.

Getting started

If you have even a hundred past customers in a spreadsheet, you have an email marketing programme waiting to happen. Start simple, stay consistent, and it will quietly become one of your most reliable sources of repeat work.
