Reconciling against the vendor’s own dashboard

Where to look in Mailchimp’s own dashboard: The Mailchimp dashboard surfaces this metric (or its components) under the relevant report section. Confirm period boundaries and filter settings match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ:
ReasonDirectionWhat to do
Period boundary. Vortex IQ uses 30-day rolling by default; vendor dashboards may use calendar periods.VariableMatch the period range.
Time zone. Vendor uses account time zone; Vortex IQ aligns to merchant reporting time zone.MarginalConfirm time zone match.
Filter scope. Profile-level filters (channel, B2B, test orders) may narrow the Vortex IQ view.VariableMatch filter settings.
Cross-connector reconciliation: complement with sibling cards in the same category for the full diagnostic picture. For divergence investigations, use Vortex Mind.

Known limitations / merchant FAQs

Q: How often does Audience Growth 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 Mailchimp 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 Audience Growth Rate relate to other audience & segmentation 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.
