A high-quality email list is fundamental to any email marketing strategy. Without the right recipients, even the best email content will fall flat.

How to Build an Email List

  • Opt-In Forms: Use forms on your website, blog, or landing pages to collect email addresses. Ensure compliance with laws like GDPR by gaining explicit consent.

Example: An online retailer can segment customers into categories like “first-time buyers” and “returning customers” and tailor campaigns for each group.


5. Write Compelling Subject Lines

The subject line is the first thing recipients see, making it a critical component of email marketing.

Best Practices

  • Keep it Short: Subject lines with fewer than 50 characters have a higher open rate (Marketing Sherpa).
  • Personalize: Emails with the recipient’s name in the subject line have a 26% higher open rate, according to Experian.

Why It Matters

With 81% of emails opened on mobile devices, optimizing for mobile users is non-negotiable (Litmus).

Key Elements

  • Clickable CTAs: Buttons should be large and easily tappable.

7. Craft Engaging Content

The content of your email must provide value to the recipient to encourage engagement and action.

A strong CTA directs readers on what to do next, driving clicks and conversions.

Best Practices

  • Use action-oriented phrases like “Shop Now” or “Sign Up Today.”
  • Place the CTA prominently and make it visually distinct.
  • Limit emails to one primary CTA to avoid confusion.

Fact: Emails with a single CTA can increase clicks by up to 371%, according to WordStream.


9. Automate Your Email Campaigns

Benefits of Automation

Email automation saves time and ensures timely delivery of relevant content.

Automation Examples

  • Welcome Series: Greet new subscribers with a series of onboarding emails.
  • Abandoned Cart Emails: Recover lost sales by reminding users to complete their purchase.
  • Re-Engagement Campaigns: Reach out to inactive subscribers to rekindle interest.

Key Metrics to Track

  • Open Rate: Indicates how many recipients opened your email.
  • Click-Through Rate (CTR): Measures the percentage of recipients who clicked on a link or CTA.
