How Webhooks Work

SendPost listens to email events, formats them into a clean JSON structure, and fires them to your configured endpoints in real-time.

Configure Endpoints

Create one or more webhook URLs and define which events should trigger calls.

2

Send Email & Monitor Events

As your emails are processed, opened, clicked, or bounced — webhook events are triggered.

3

Integrate & Automate

Connect your CRM, dashboards, analytics systems, or workflows for real-time automation.
