Known limitations / merchant FAQs

Q: How often does Email Open Rate update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. Q: Why does my Brevo (Sendinblue) dashboard show a different number? The most common reasons are period-boundary differences (Vortex IQ uses 30-day rolling vs vendor’s calendar months), time-zone alignment, and filter scope (profile-level vs vendor’s all-account view). Match these settings before assuming a real divergence. Q: How does Email Open Rate relate to other klaviyo overview metrics? Track this card alongside the siblings listed above to build a complete picture. Single-metric reads can mislead; the diagnostic value is in the cross-reference. Q: Can I customise the alert threshold? Yes, sensitivity thresholds are configurable per profile in the Sensitivity tab. Adjust to match your business baseline rather than relying on the generic default.
