Email Marketing: The Strategy That Never Goes Out of Style (And Generates the Highest ROI)

Do you think email is dead? That social media has replaced it? Huge mistake. While everyone chases the latest TikTok algorithm, smart marketers continue building empires with the oldest and most profitable digital marketing strategy: Email Marketing.

For every euro invested in email marketing, companies get an average return of 36 euros. Yes, you read that right. No other digital strategy comes even remotely close to these numbers. And no, it’s not a coincidence.

What Exactly Is Email Marketing?

Email Marketing is the process of sending commercial messages to a group of people who have given their consent to receive them, with the goal of building relationships, generating sales, and retaining customers.

🎯 Key Components of Email Marketing:

Subscriber list: People who voluntarily gave their email
Relevant content: Messages that provide real value
Segmentation: Dividing the audience for more personalized messages
Automation: Sequences sent based on behaviors
Metrics: Data to measure and optimize results

💡 Why Does It Work So Well?

It’s personal: Reaches directly to their inbox
You have total control: You don’t depend on third-party algorithms
It’s scalable: You can send to 100 or 100,000 people
It’s measurable: Every click, open, and conversion is trackable
It’s economical: Minimal cost compared to other channels

The Myths That Are Killing Your Email Marketing

❌ Myth #1: “Email Is Dead”

The reality: There are more than 4 billion email users in the world. That’s more than Facebook, Instagram, and Twitter combined.

Data that proves it:

The average worker receives 121 emails per day
73% of millennials prefer email communication for business

❌ Myth #2: “It’s Spam and Annoys People”

The reality: Social media complements, doesn’t replace email.

Real comparison:

Email: 3.7% average conversion rate
Facebook: 0.9% conversion rate

Writing Emails People Actually Want to Read

✍️ Subject Lines That Open Emails

Curiosity Gap:

“The mistake 90% of entrepreneurs make (and how to avoid it)”
“Why I stopped using Facebook Ads (and what I do now)”
“The secret strategy that generated €100K last year”

Urgency + Scarcity:

“Only 24 hours: 50% OFF all courses”
“Last 3 spots available for workshop”
“Definitive closure tomorrow at 11:59 PM”

Personal + Benefit:

“[Name], how to double your productivity in 30 days”
“Maria, this could change your business forever”
“The tool that saves me 10 hours weekly”

Question Hook:

“Why do 95% of startups fail?”

“What’s the biggest email marketing mistake?”

Subject Lines to NEVER use:

📝 Anatomy of a Perfect Email

The 35-90 characters that appear after the subject line

Immediately hooks with story or benefit
Avoid generic greetings like “Hope you’re well”

3. Body

One main idea per email maximum
Short paragraphs (1-3 lines)
Use bullets, numbers, emojis for easy scanning
Conversational tone, like writing to a friend

4. Call to Action (CTA)

Only one main per email
Clear and specific: “Download the guide” vs “Click here”
Create urgency or scarcity if applicable

5. Signature

Personal, with photo if possible
Links to social media
Clear and easy unsubscribe link
