# Mailgun KPIs, Vortex IQ Nerve Centre

> Every Mailgun KPI pulse Vortex IQ Nerve Centre tracks: 29 metrics covering revenue, orders, customers, refunds, and more.

Vortex IQ Nerve Centre tracks **29** KPI pulses for Mailgun stores. Each metric has its own page: definition, calculation, why it matters, and what to do when it moves.

The Mailgun connector brings the Vortex IQ **AI OS** to teams running transactional email through Mailgun - receipts, password resets, alerts, and other app-triggered messages where deliverability and latency matter more than marketing engagement. The **Nerve Centre** tracks 29 KPI pulses for Mailgun accounts including deliverability, bounce, and engagement metrics. **Vortex Mind** investigates when a number moves; **Ask Viq™** lets you ask in plain English with citations back to the source card.
