If the Klaviyo numbers in your PMA reports don't match your Klaviyo dashboard, you're not looking at an error. The two systems measure performance in different ways. This article explains why the numbers differ, what to expect, and how to compare the two accurately.

Why the Numbers Differ

Klaviyo provides two separate reporting methods, and Power My Analytics and the Klaviyo dashboard each use a different one.

Klaviyo's own developer documentation confirms that data from these two methods will not match. Neither number is wrong; they answer different questions. The Klaviyo dashboard answers "what did the messages I sent during this period eventually produce?" PMA answers "what activity happened during this period?"

A Quick Example

Suppose a flow email goes out on April 30, the recipient opens it on May 2, and they place an order on May 3:

• Your Klaviyo dashboard credits the open and the order to April 30 (the send date).
• Your PMA report counts the open on May 2 and the order on May 3 (the dates the events happened).

Same activity, different dates. Over long date ranges the totals converge; over short date ranges (or near the edges of any range) they can differ noticeably.

Why PMA Reports by Event Date

Klaviyo's dashboard-matching Reporting API allows only 225 requests per day per account, with a maximum of one conversion metric per request. That capacity is not enough to collect every metric for every campaign, flow, and account every day. The Metric Aggregates API that PMA uses has no daily cap, which lets your daily Data Sync collect your complete Klaviyo data reliably.

The data PMA delivers is a correct and complete record of your Klaviyo events, verified directly against Klaviyo's API.

What You'll See in Your Reports

• Differences in both directions. Depending on when events occur relative to your date range, PMA totals can be higher or lower than the Klaviyo dashboard for the same period.
• Larger differences for flows. Flows send continuously, so the send-date and event-date views diverge more than they do for one-time campaigns.
• Conversion metrics differ the most. Attribution windows mean a purchase can be credited days after the message that drove it was sent.
• Klaviyo CSV exports match the dashboard, not PMA. Exports come from the same reporting method as the dashboard, so comparing a Klaviyo export to PMA shows the same expected differences.

How to Compare PMA and Klaviyo Accurately

1. Use Klaviyo's single metric deep dive report for comparisons. It groups by event date (the same method PMA uses), so it aligns much more closely with your PMA data than the campaign or flow performance dashboards do.
2. Use longer date ranges, and compare complete months where possible. Differences shrink as the date range grows.
3. Filter flows to match your dashboard view. PMA collects data for all of your flows; use the Flow Status dimension to exclude archived or draft flows that your Klaviyo dashboard may not display.
4. Expect edge effects. Events that happen shortly after your date range ends belong to messages sent inside it, and vice versa.

When to Contact Support

If you see a difference that doesn't fit the patterns above (for example, a metric showing 0 in PMA while your Klaviyo dashboard shows data), our support team is happy to investigate. Please submit a ticket and include your report link, the date range, and the specific metrics you're comparing.
