Klaviyo Metrics & Reporting: The KPIs That Actually Matter

Quick answer: The Klaviyo metrics that actually matter are revenue per recipient, placed-order (conversion) rate, and flows-vs-campaigns revenue share — not opens. Open rates have become noisy due to privacy changes, so judge sends on the money they make. Aim for flows to drive ~30%+ of email revenue, keep unsubscribe under 0.2% and spam complaints under 0.1%, and watch revenue per recipient trend up over time.

Key takeaways

• Revenue per recipient (RPR) is the truest ranking of any send.
• Don’t optimize on opens — privacy changes made them unreliable.
• Track flows vs campaigns revenue share; flows should be ~30%+.
• Keep unsubscribe < 0.2% and spam complaints < 0.1%.
• Build a simple dashboard of these few numbers rather than drowning in data.

Klaviyo’s analytics can overwhelm you with numbers. Here’s the short list that actually drives decisions. This operationalizes our Klaviyo best practices playbook.

The KPIs that matter

Focus your reporting on these, with healthy benchmarks:

Campaign metrics

For one-off campaigns, look at:

• Revenue per recipient — the number that ranks your campaigns honestly.
• Placed-order rate — ~1–3% is typical for a segmented campaign.
• Click rate — directional engagement signal (~2–3%).
• Unsubscribe / spam rate — early warning that you’re over-sending or off-target.

Flow metrics

For automations, the questions are different:

• Revenue per recipient per email — which message in the flow is carrying it, and which is dead weight.
• Conversion rate per step — where people convert (or drop).
• Flow share of email revenue — are your flows pulling their weight?

How Klaviyo revenue attribution works

Klaviyo attributes a conversion to an email or SMS if the recipient places an order within a set window after engaging (by default, a few days for email). Understanding this matters: attributed revenue is influenced by the attribution window, so compare like with like and don’t double-count email and SMS for the same order. Use attributed revenue to rank sends, but sanity-check against your store’s total revenue.

Benchmarks by metric

Directional targets for segmented, engaged sends:

• Open rate: ~40–50% (noisy — don’t over-index on it).
• Click rate: ~2–3% campaigns.
• Placed-order rate: ~1–3% campaigns.
• Flows revenue share: ~30%+ of email revenue.
• Unsubscribe: < 0.2%; spam complaints: < 0.1%.

These vary by industry and list quality — use them as a compass, not a verdict.

Building a custom dashboard

Don’t monitor everything. Build a simple dashboard with four or five tiles: revenue per recipient (campaigns and flows), flows-vs-campaigns share, list growth, and deliverability (unsub/spam). Review it monthly so trends surface before they cost you. Anything beyond these is usually a distraction.

Red flags to watch

• Flows under ~25% of email revenue — you’re under-automating.
• Declining open trend on engaged segments — possible deliverability slippage; check the deliverability guide.
• Rising unsubscribe/spam — you’re sending too often or to the wrong people.
• Revenue per recipient flat or falling — your offers or targeting need work.

Frequently asked questions

What’s the most important metric in Klaviyo?

Revenue per recipient. It ranks every send by the money it actually makes, which is more honest than opens or clicks — especially since privacy changes made open rates unreliable.

Why shouldn’t I rely on open rates in Klaviyo?

Apple Mail Privacy Protection and similar features auto-load images, inflating and distorting open counts. Open rate is still a directional signal, but judge performance on revenue per recipient and placed-order rate instead.

What percentage of revenue should come from Klaviyo flows?

For most ecommerce brands, flows should contribute around 30% or more of email revenue. If you’re under ~25%, you likely have missing or under-built automations.

How does Klaviyo attribute revenue?

Klaviyo credits a conversion to an email or SMS when the recipient places an order within an attribution window after engaging. Be mindful of the window when comparing sends, and avoid double-counting the same order across email and SMS.
