Email Segmentation

Email segmentation is the practice of dividing your subscriber list into smaller, targeted groups based on criteria like demographics, purchase history, engagement level, or signup date. Segmented campaigns send relevant content to each group, improving open rates, click rates, and reducing unsubscribes compared to sending the same email to everyone.

Common Segmentation Criteria

  • ●Engagement: Active vs inactive subscribers (last open/click within 30/60/90 days)
  • ●Signup date: New subscribers vs long-term subscribers
  • ●Purchase behavior: First-time vs repeat buyers, high-value vs low-value
  • ●Location: Geographic segments for localized content or timezone-optimized sending
  • ●Preferences: Topics or categories the subscriber opted into
  • ●Industry/Role: B2B segmentation by company type or job function
