The Most Important KPIs in Email Marketing

1. Open Rate

The open rate indicates how many recipients have actually opened your email. A low rate may suggest unappealing subject lines or inadequate segmentation.

Calculation: (Number of opened emails / Number of delivered emails) × 100

Tips for Optimization:‍

• Use personalized subject lines
• Conduct A/B testing for different subject lines
• Optimize the sending time

2. Click-Through Rate (CTR)

This metric measures the percentage of recipients who clicked on a link in the email.

Calculation: (Number of clicks / Number of delivered emails) × 100

Tips for Optimization:‍

• Use clear and visible calls-to-action (CTAs)
• Ensure mobile-optimized design
• Personalize content

3. Conversion Rate

The conversion rate indicates how many recipients completed the desired action after clicking a link (e.g., purchase, signup, download).

Calculation: (Number of conversions / Number of clicks) × 100

Tips for Optimization:‍

• Align landing pages with the campaign
• Build trust with customer reviews and guarantees
• Present a clear and attractive offer

4. Unsubscribe Rate

This metric shows how many recipients unsubscribed after receiving an email.

Calculation: (Number of unsubscribes / Number of delivered emails) × 100

Tips for Optimization:‍

• Provide more targeted and relevant content
• Adjust email sending frequency
• Make the unsubscribe process simple and transparent

5. Bounce Rate

The bounce rate indicates how many emails were not delivered. There are "soft bounces" (temporary issues) and "hard bounces" (permanent errors).

Calculation: (Number of undelivered emails / Number of sent emails) × 100

Tips for Optimization:‍

• Regularly clean the email list
• Ensure valid and up-to-date email addresses
• Use double opt-in to avoid incorrect addresses

6. Spam Complaint Rate

This metric shows how many recipients marked your email as spam.

Calculation: (Number of spam complaints / Number of delivered emails) × 100

Tips to Reduce Complaints:‍
