How It Works

Three steps to unified data

1

Get your webhook URL

Each sending identity gets a unique, secure webhook endpoint. Copy it from your Engagor dashboard.

https://ingest.engagor.io/v1/{tenant}/{identity}
2

Configure your ESP

Paste the URL into your ESP's webhook settings. Enable delivery events, opens, clicks, bounces, complaints.

delivered bounced opened clicked complained

See unified data

Events stream in real-time. Engagor normalizes everything into a unified schema — regardless of which ESP sent it.
