Email marketing basics, the small business channel that still beats social media

If you had to bet on one marketing channel actually turning into sales, the data says it shouldn't be social media, it should be email.

Email marketing consistently returns somewhere between £36 and £45 for every £1 spent, compared to roughly £3 to £5 for social media advertising, and email converts at around 4% compared to social media's well under 1%.

That's not a small gap –, it's close to a sevenfold difference, and it holds up year after year despite how much attention social platforms get.

The reason isn't complicated once you think about it properly. Everyone on your email list opted in, they gave you their email address because they already wanted to hear from you, whereas most people seeing your social posts are scrolling past content from hundreds of accounts with no particular intent to engage with yours.

Email also belongs to you. Your list is yours to keep regardless of what an algorithm decides to show or hide, or what happens to a platform's reach overnight, something social media has proven, repeatedly, it can't promise.

None of this means abandon social media, it still matters for visibility and discovery.

But if you've been pouring most of your marketing time into posting and very little into your email list, the balance is probably backwards. Nearly half of marketers rate email as their most effective channel, twice the rate for either social media or paid search, and for small businesses specifically, it's consistently the best-performing channel for keeping existing customers coming back, not just finding new ones.

Here's how to actually start, if you haven't.

Pick one simple reason for someone to give you their email address, like a discount on a first order offer, a genuinely useful guide, early access to new products or availability, anything with real value attached.

Set it up somewhere visible on your website and any relevant social bios. Then commit to one regular send, whether that's weekly, fortnightly or monthly. Consistency matters more than frequency.

Keep it short and useful rather than trying to write a newsletter that reads like a press release. People open emails that feel like they're actually written by a person, not a marketing department.

The most common mistake small businesses make once they've started is treating the list as a one-way broadcast channel rather than a relationship. Emails that just say "buy this" repeatedly get ignored and unsubscribed from. Emails that mix in something genuinely useful, a tip, a behind-the-scenes look, an honest update, alongside the occasional offer, build the kind of trust that makes the eventual sell land better when it does happen.

If you're not sure how to fit an email list into what you're already doing on social and your blog, that's a genuinely useful thing to plan properly rather than bolt on as an afterthought, and it's exactly the kind of ongoing content support worth talking through.
