1. Introduction: Why Email Marketing Still Works

Email remains one of the most direct and cost-effective ways to reach an audience. With nearly 4.5 billion global users in 2025, it’s a channel that isn’t fading. Importantly, it gives business owners control: you own the list, not an algorithm.

For time-poor business owners, email marketing works in the background. When structured correctly, it delivers leads, supports sales, and reinforces brand recognition with minimal manual effort.

2. The Value Proposition: ROI, Access and Relationship-Building

Email marketing continues to outperform many channels. The average ROI sits around $36 to $44 for every dollar spent. For some ecommerce campaigns, it climbs even higher.

Email is more than a sales channel. It’s a relationship builder. Campaigns are trackable and measurable, letting you adjust based on real engagement. And it’s direct – not filtered by a platform’s newsfeed or algorithm.

3. Start With Strategy: What Do You Want Your Emails to Achieve?

Every email must have a clear purpose and goal. That might be increasing website traffic, guiding prospects through a funnel, retaining existing customers, promoting a specific product or event, or just being front of mind.

Define the goal before writing the message. Data shows that aligning email campaigns with broader marketing goals significantly boosts engagement and ROI.

4. Build a Healthy List: Quality Vs Quantity

High engagement from a smaller list often delivers more value than an extensive database. This is because it is easier to target a smaller number of targeted prospects addressing their pain points with pin point accuracy.

It’s important to also note that engagement and open rates will vary greatly across industry sectors. So see how your industry ranks with open rates of 50% or more. This will help you have a realistic expectation around your campaign performance.

Keep your list clean by removing inactive subscribers regularly. Make it easy to unsubscribe – this protects your sender reputation and improves trust with your audience and also ensures you are complying with consumer laws.

5. Craft Messages That Matter: Content That Converts

Well planned and crafted content is what drives conversion.

Start with a compelling subject line. Your opening sentence should immediately hook the reader. Structure the message so it’s scannable and clearly written with a single call to action.

Personalisation helps too. Emails with personalised subject lines are 26% more likely to be opened, and segmented campaigns can result in 760% more revenue.

Here’s an example: CMX Insurance partnered with Content Box to bring consistency and strategy to their email marketing.

Previously reliant on sporadic newsletters, they shifted to a structured campaign model tailored to client lifecycle stages.

As owner Cindy Lau shared, “Stacy has become a very important member of the CMX team… What I love most is that she keeps on top of my marketing so I don’t need to worry about it, and I can focus on running my business.”

That shift not only increased engagement but freed up Cindy’s time to focus on what she does best, delivering client services – demonstrating how a well-designed email strategy delivers both peace of mind and tangible results.

6. Design for Engagement: Mobile First, User Focused

A lot of people read emails on their phones, with mobile opens accounting for over 41.6% of email views. That means single-column layouts, concise text, tappable buttons, and fast-loading images are all must-haves.

Design with accessibility in mind – consider font sizes, alt text, and sufficient colour contrast. Always send yourself a test email and view it on a mobile device before hitting send.

7. Automate With Intelligence: Sequences That Serve Your Strategy

Automation increases efficiency.

A welcome sequence, abandoned cart reminders, and re-engagement emails are all proven to lift conversions. Brands using a series of three cart reminders recover up to 69% more sales.

However, don’t let automation go stale. Review your sequences quarterly. Make sure your content still aligns with your goals and continues to speak to your audience’s needs.

8. Segment and Personalise: Relevance Drives Results

Relevance is the backbone of successful email campaigns.

According to HubSpot, segmented campaigns achieve higher open rates and lower unsubscribe rates than general campaigns.

Begin by segmenting your list based on purchase history, behaviour, pain points or geography. Even basic personalisation, like first names or referencing a past interaction, can significantly improve results.

Here’s how we approach customer segmentation.

9. Track, Test and Tweak: Data-Led Improvements

Watch your metrics closely.

Open rates show if your subject lines are effective. Click-through rates indicate content relevance. Conversion rates reflect how well you’re driving action. High unsubscribe rates might suggest you’re off the mark in tone or frequency.

A/B testing improves performance. Small changes – like a revised headline or a different CTA – can deliver big results. Regular testing and adjusting ensures your campaigns stay effective.

10. Email Marketing Tools That Work for SMEs

You don’t need enterprise software to see results.

Tools like Mailchimp, ActiveCampaign, Klaviyo, Campaign Monitor, and Brevo (Sendinblue) offer affordable, scalable solutions. Choose based on your needs: automation, e-commerce integration, or ease of use.

Start with a free tier to assess fit, then upgrade as you grow.

11. Common Mistakes to Avoid in 2025

Avoid sending emails too frequently or without a clear purpose in mind. Avoid buying lists, which leads to poor deliverability. And don’t forget to test for mobile responsiveness – it’s one of the most common pitfalls.

Above all, make sure your content is valuable. Every message should be useful, relevant, and aligned with your brand voice.

12. Future-Proofing Your Email Marketing

Looking ahead, email marketing is evolving. AI is helping marketers optimise timing and content. Interactive emails are increasing engagement. And with privacy laws tightening, owning first-party data is more essential than ever.

Ensure your email strategy supports your broader ecosystem, integrating with your website, CRM, and social channels.

13. Conclusion: Email Isn’t Dead, It Just Needs to Be Done Well

Email still continues to outperform other marketing channels, especially when used intentionally. Start small, build a list that wants to hear from you, and focus on clear messaging that reflects your goals.

FAQs

1. How often should I send marketing emails?

Start with monthly sends. Adjust based on engagement metrics like open rates and unsubscribes. I don’t recommend sending more than 2 emails each month, unless you are running a specific campaign.

2. What’s the best time to send emails?

Midweek mornings tend to perform well, but test to find what suits your audience. I have found Tuesdays and Wednesdays to be very busy email marketing days and have started testing with other days of the week. So review your open and engagement rates then decide. Keep your cadence consistent, whatever day you decide on.

3. How do I grow my list ethically?

Offer valuable lead magnets and ensure sign-ups are fully consented. Avoid shortcuts like buying lists. Create a sign up from on your website and encourage people via social media posts to sign up. Also networking events are a great opportunity to build lists, but remember to gain a person’s consent first.

4. What metrics matter most?

Open rates, click-throughs, conversions, and unsubscribes give you a good snapshot of email performance.

5. Can I manage this without a marketing team?

Yes you can, providing you have the right strategy with the right content. Without this fundamental base, no matter how good your set up skills are, your email campaigns are set to flop. So ensure you have the right strategic approach and a solid marketing strategy in place first. If not, speak to us and we can help get these foundations in place.
