7. Crafting a High-Converting Email

7.1 Write a Killer Subject Line

Your open rate depends on it. Use curiosity, urgency, or personalization.

Examples:

• “Oops, did you forget this?”

• “Your 20% discount expires today!”

• “Hi [First Name], you’ll love this update”

7.2 Personalize the Content

Use dynamic content blocks, names, or segmented offers.

Don’t overwhelm the reader. One clear button is more effective than five links.

7.4 Design for Mobile

Use a single column layout and readable font sizes.

7.5 Test Before Sending

Preview your email on desktop and mobile. Send a test email to yourself first.

What to Look for in an Email Platform

• Segmentation: So you can send the right message to the right people.

• Templates: Built-in design templates to speed up campaign creation.

9. Compliance: GDPR, CAN-SPAM, and Other Legal Essentials

Sending emails without understanding legal obligations can result in hefty fines and loss of trust. Here’s a quick rundown:

GDPR (General Data Protection Regulation)

• Applies to: EU residents, even if your business is outside the EU.

• Requirements:

  • Get explicit consent before collecting emails.

  • Offer easy opt-out mechanisms.

  • Let users access or delete their data.

CAN-SPAM Act (USA)

• Don’t use misleading subject lines.

• Identify the message as an ad.

• Include a valid postal address.

• Include a clear unsubscribe link.

Other Global Laws

• CASL (Canada): Requires express consent.

• Privacy and Electronic Communications Regulations (UK): Similar to GDPR.

10. Measuring Success: Key Metrics to Track

Understanding performance is essential to optimizing your strategy.

📊 Key Metrics

📈 Tips to Improve Metrics

• A/B Test subject lines and CTAs.

• Keep email content relevant and timely.

• Personalize wherever possible (name, past behavior).

• Clean your list regularly to remove inactive subscribers.

11. Common Mistakes to Avoid

Even experienced marketers fall into these traps—avoid them from day one:

❌ Mistake 1: Not Segmenting Your List

Sending the same email to everyone results in lower engagement. Use segmentation by:

• Location

• Behavior (opens, clicks, purchases)

• Interests (based on survey or signup form)

❌ Mistake 2: Ignoring Mobile Users

Over 60% of emails are read on smartphones. Use:

• Mobile-optimized templates

• Short subject lines

• Readable fonts and button-based CTAs

❌ Mistake 3: Sending Too Frequently or Infrequently

• Too many emails = unsubscribes

• Too few = you’ll be forgotten

Use a consistent schedule and give subscribers control over frequency.

❌ Mistake 4: No Clear Call-to-Action (CTA)

Every email should have one clear goal. Don’t confuse your readers with too many buttons or links.

12. Tips for Beginners to Succeed

Starting can be intimidating—but you don’t have to get it perfect. Here’s how to grow faster and smarter:

✅ 1. Focus on Value First

Don’t just promote—educate, entertain, inspire. Offer content people look forward to reading.

✅ 2. Nail Your Subject Line

Your open rate depends heavily on it. Test formats like:

• “Quick Question, [First Name]…”

• “Here’s your 10% off code!”

• “3 Mistakes You’re Making in Email Marketing”

✅ 3. Use a Welcome Sequence

Automate your first impression with a series of emails that:

1. Welcome the subscriber

2. Share your best content

3. Offer a small product or discount

4. Ask for feedback or preferences

✅ 4. A/B Test Everything

Even simple tests—subject lines, sending times, CTA placement—can yield major performance insights.

✅ 5. Clean Your List Every 3–6 Months

Remove inactive subscribers who haven’t opened an email in 90+ days. It improves deliverability and accuracy of data.
