Target ML diagnosis for campaign anomalies

Performance questions often arrive before teams agree on what a useful explanation means.

Speed, confidence, and actionability can point toward different diagnostic experiences.

I don’t need another chart—I need to know what’s worth changing before the next send.

Annemarie Visser · Growth Lead

She runs weekly lifecycle campaigns for a home-goods brand and must explain performance changes before deciding what to alter.

What pulls against what

  • fast explanations vs. defensible inference
  • merchant actionability vs. analytical uncertainty
  • general patterns vs. account-specific context

What is at stake

Choosing the wrong diagnostic outcome creates polished explanations that do not improve merchant decisions

Why Klaviyo

At Klaviyo, merchants often need to interpret changing customer response before their next lifecycle decision.

This is the setup. The work is inside.

Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
