Connect your email infrastructure.
Engagor connects to your existing email service providers and MTAs, unifying deliverability data from every source into a single platform. Whether your ESP pushes data to us or we pull it via API, you get complete visibility.
What we capture from every ESP
Regardless of integration method, Engagor normalizes these email events into a unified schema.
Your MTA. Our intelligence.
Engagor ingests raw SMTP logs from any on-premise MTA, parsing bounces, deferrals, delivery confirmations, opens, clicks, unsubscribes, and complaint feedback loops.
