Email Marketing: The Channel You Actually Own

Your email list is the only marketing channel you actually own. Social media platforms can change their algorithm, restrict your reach, or disappear entirely. Google can update its rankings overnight. But the people who’ve given you their email address and said “yes, I want to hear from you” — that relationship is yours.

Email marketing is also, consistently, one of the highest-ROI channels in digital marketing. The average return on email spend is somewhere between £35–£45 for every £1 invested, depending on the industry and how well it’s done. Nothing else in digital comes close at that cost basis.

What Email Marketing Actually Covers

It’s more than sending a monthly newsletter. Properly set up, email marketing includes:

• Broadcast campaigns — one-time sends to your list (announcements, promotions, content)
• Automated sequences — triggered by actions (welcome series, post-purchase, abandoned cart, re-engagement)
• Segmented sends — different messages to different parts of your list based on behaviour, purchase history, or demographics
• Transactional emails — order confirmations, receipts, shipping updates (often underestimated as a marketing touchpoint)

Most businesses only do the first one. The real leverage is in automation — emails that go out without anyone pressing send, at exactly the right moment in the customer relationship.

Building a List Worth Having

A big list of unengaged people is worth less than a small list of people who actually want to hear from you. How you build your list matters:

• Opt-in incentives that match your audience — a discount code if you’re e-commerce, a useful guide if you’re a service business, early access if you’re product-based
• Clear value proposition — tell people what they’re signing up for, not just “join our newsletter”
• Consistent quality — people stay subscribed (and open your emails) because they’ve learned it’s worth their time

Never buy email lists. Beyond being largely illegal under GDPR, bought lists are full of people who didn’t ask to hear from you, which means terrible open rates, spam complaints, and a damaged sending reputation that takes months to fix.

What to Expect — Realistic Timelines

• Month 1: Setup — ESP (email service provider), opt-in forms, basic welcome automation. Your first sends.
• Month 2–3: List starts to grow. You’re learning what your audience responds to. Open rates stabilise.
• Month 3–6: Automation doing real work. Consistent send cadence established.
• 6 months+: Segmentation, A/B testing, list health management. This is where it gets sophisticated.

Email vs Other Channels

The Automation Opportunity Most Businesses Miss

The welcome email is the most-opened email you’ll ever send. Someone just signed up — they’re at peak interest. Most businesses send a generic “thanks for subscribing” and squander it. A well-crafted welcome sequence that introduces who you are, delivers on whatever you promised, and starts building the relationship will outperform any broadcast campaign you send all year.

Set it up once. It runs forever. That’s the power of automation.

Frequently Asked Questions

Which email marketing platform should I use?

For most businesses starting out: Mailchimp (free up to 500 contacts, good enough for basics) or Kit (formerly ConvertKit — better for content creators and service businesses). For e-commerce, Klaviyo. For businesses that want serious automation and CRM integration, ActiveCampaign or HubSpot. Don’t overthink the tool — start simple and migrate when you outgrow it.

How often should I email my list?

Enough to stay present, not so much that people unsubscribe. For most businesses, once a week is a realistic ceiling. Once a fortnight or monthly is fine if your content quality is high. The right frequency is the one you can maintain consistently without the quality dropping. Irregular, sporadic emails are worse than a predictable cadence.

What’s a good open rate?

It depends heavily on industry and list size. Generally: 30%+ is healthy, 20–30% is average, below 20% suggests list hygiene or content quality issues. Since Apple’s Mail Privacy Protection (2021), open rates have been inflated for iOS users, so trend direction matters more than absolute numbers. Click rate is now a more reliable signal of genuine engagement.

Is cold email the same thing?

No. Cold email (reaching out to people who haven’t opted in) is a different discipline — closer to sales than marketing, and highly regulated under GDPR for B2C. For B2B, there are legitimate cold email approaches, but they require careful targeting, personalisation, and legal compliance. Conflating cold email with email marketing is a common and expensive mistake.

What do I do about GDPR?

The basics: you need explicit consent to email people for marketing purposes, a clear unsubscribe mechanism in every email, and a privacy policy. Don’t add people to marketing lists without their knowledge. Don’t buy lists. Document how you collect consent. If you’re doing those things, you’re covering the essential bases — but get proper legal advice if you’re handling significant volumes of personal data.

My list has gone cold. What do I do?

Run a re-engagement campaign. Send a direct email acknowledging you’ve been quiet, explain why it’s worth staying on the list, and include something genuinely useful or valuable. Accept that some people will unsubscribe — that’s fine. A smaller, engaged list beats a large, dead one every time. After the re-engagement campaign, remove anyone who didn’t open or click.
