From a0d92be8a8575ff2f9424a0564b2a7a23015d999 Mon Sep 17 00:00:00 2001 From: Daniel Sousa Date: Tue, 12 May 2026 15:59:03 -0300 Subject: [PATCH] docs: clarify Open Rate formulas for Prefetched Opens toggle Split the Enterprise "Open Rate" definition into two rows matching the "Include Prefetched Opens" / "Exclude Prefetched Opens" toggle in the Analytics Report UI, so the documented formula matches what the UI actually computes. Also adds the `count_nonprefetched_unique_confirmed_opened` API metric (referenced by the new formula) to the API metrics table. --- content/docs/reporting/enterprise-metrics-definitions.md | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/content/docs/reporting/enterprise-metrics-definitions.md b/content/docs/reporting/enterprise-metrics-definitions.md index 835efa07c..95821ea8b 100644 --- a/content/docs/reporting/enterprise-metrics-definitions.md +++ b/content/docs/reporting/enterprise-metrics-definitions.md @@ -1,5 +1,5 @@ --- -lastUpdated: "02/08/2020" +lastUpdated: "05/12/2026" title: "Enterprise Metrics Definitions" description: "Metrics definitions for Enterprise accounts" --- @@ -44,6 +44,7 @@ The metrics available are: | Unique Clicks Approximate | `count_unique_clicked_approx` | Number of emails that had at least one link clicked.
