Klaviyo & Email
Segmentation (Email)
Quick definition
Splitting your email list into groups based on behavior, profile, or purchase data so each group receives relevant messaging.
What it actually means
Segmentation is the difference between a list that generates revenue and one that damages sender reputation. A good Klaviyo setup segments subscribers by engagement, last 30, 60, or 90 days, purchase recency, product affinity, average order value, and predictive lifetime value. Sending the same email to all subscribers wastes reach and hurts inbox placement. Sending only to engaged users also protects sender reputation with Gmail, Yahoo, and Apple Mail.
