Despite predictions of its demise for over a decade, email marketing consistently delivers some of the highest returns on investment in digital marketing. Unlike social media, where algorithms control who sees your content, email gives you direct, owned access to your audience. Here’s how to make the most of it.
1. Build Your List the Right Way
A smaller, engaged list always outperforms a large, disinterested one. Effective list-building tactics include:
- Offering a genuinely useful lead magnet (e.g., a checklist, template, or discount)
- Using exit-intent popups sparingly and with clear value propositions
- Collecting emails at checkout or during account creation (with proper consent)
Avoid buying email lists — they’re low-quality, hurt deliverability, and often violate anti-spam regulations.
2. Segment Your Audience
Blasting the same message to your entire list wastes the channel’s potential. Segment based on:
- Purchase history or behaviour on your site
- Engagement level (active vs. dormant subscribers)
- Stage in the customer journey (new subscriber vs. repeat customer)
Segmented campaigns consistently see higher open and click-through rates than one-size-fits-all sends.
3. Nail the Subject Line and Preview Text
Your subject line’s only job is to earn the open. Best practices:
- Keep it short and specific — vague clickbait hurts trust over time.
- Test personalisation (first name, location, past purchase) against generic subject lines
- Use the preview text as a second chance to add context, not just a repeat of the subject line.
4. Automate the Journeys That Matter
Automated email sequences run in the background and often outperform one-off campaigns:
- Welcome series for new subscribers
- Abandoned cart emails for e-commerce
- Re-engagement campaigns for subscribers who’ve gone quiet
- Post-purchase follow-ups to encourage reviews or repeat purchases
5. Design for Mobile and Skimmability
Most emails are opened on mobile devices first. Keep designs simple:
- Single-column layouts that render well on small screens
- Short paragraphs and clear, scannable headers
- One primary call-to-action per email — too many options reduce clicks on any single one.
6. Protect Your Sender Reputation
Deliverability determines whether your emails reach the inbox appropriately. Maintain good sender health by:
- Regularly removing unengaged subscribers.
- Authenticating your domain with SPF, DKIM, and DMARC
- Monitoring bounce rates and spam complaints
7. Measure What Matters
Beyond open rates (which have become less reliable due to Apple Mail privacy features), focus on:
- Click-through rate
- Conversion rate per campaign
- Revenue per email sent.
- List growth rate vs. unsubscribe rate
The Bottom Line
Email marketing works because it’s permission-based, direct, and highly measurable. The brands that succeed with email marketing treat their list as a relationship to nurture, not a megaphone to broadcast through — segmenting thoughtfully, automating strategically, and always prioritising subscriber value over sending frequency.
