What is Email Marketing & Why Does It Matter?
Email marketing is the undisputed king of ROI when it comes to digital marketing.
Think about it: You send an email, and it lands directly in someone’s inbox. No fighting social media algorithms, no hoping your post gets seen. Just straight-up, direct communication with your audience.
If you’re not using email marketing, you’re leaving money on the table. And if you’re using it wrong, you’re annoying your audience and getting buried in spam folders.

In this guide, I’ll break down:
- How email marketing works
- The best free tools to get started
- How to create emails that people actually open and read
- Proven strategies to boost your conversions

How Does Email Marketing Work?
It’s simple.
- Build an email list – Get people to subscribe to your emails.
- Create value-packed emails – Give people a reason to open your emails.
- Send & track results – Measure what’s working and tweak what isn’t.
- Optimise for mobile – Ensure your emails look great on any device.
- Use personalisation – Tailor your emails for better engagement.
You can send:
- Newsletters – Regular updates and insights.
- Promotional emails – Discounts, offers, and product launches.
- Automated sequences – Emails triggered by actions (e.g., welcome emails, abandoned cart reminders).
- Survey emails – Collect feedback and improve your offerings.
- Re-engagement emails – Win back inactive subscribers.
If done right, email marketing can drive higher engagement and conversions than almost any other marketing channel.

How to Write Emails That People Actually Open
You could have the best product or service in the world, but if your emails are boring, no one will read them.
Here’s how to stand out:
1. Write Subject Lines That Hook Readers
Your subject line is the make-or-break moment. If it’s weak, your email goes straight to the trash.
Use these formulas:
- Curiosity – “The one mistake killing your email marketing”
- Urgency – “Only 24 hours left to grab this deal!”
- Personalisation – “Hey [First Name], here’s something for you”
- Numbers & Lists – “5 free tools to boost your email game”
2. Keep It Short & Conversational
Nobody wants to read a wall of text.
Break your email into short, easy-to-scan paragraphs. Write like you’re talking to one person, not an audience.
3. Add a Clear Call-to-Action (CTA)
Every email needs to tell the reader what to do next.
Examples:
- Sign up now
- Claim your discount
- Watch the demo
The clearer the CTA, the higher the click-through rate.
