Ep 70: Diagnosing a Drop in Email Revenue

When email revenue drops, most teams guess. This episode shows how to diagnose it systematically.

Jordan breaks down the two real drivers of email revenue decline: fewer emails sent and lower revenue per email sent — and walks through the exact hierarchy of metrics that explain what’s actually happening inside Klaviyo.

You’ll learn how to:

• Identify whether the problem is frequency, send size, segmentation, or list health
• Understand how segment mix and message mix impact revenue
• Separate real performance issues from attribution noise
• Evaluate inboxing, relevance, and engagement the right way
• Use Shopify, Klaviyo, and attribution models to determine whether purchase behavior actually changed
