webhook-processing

What problem does it solve?

This skill solves the critical challenge of reliably receiving, verifying, and processing email delivery event webhooks from major email service providers, eliminating risks of missed events, duplicate processing, unverified malicious requests, and incorrect delivery status tracking.

Core Features & Use Cases

• Multi-provider signature verification: Secure webhook validation for SendGrid, Postmark, AWS SES, Resend, and Mailgun with provider-specific implementation guidance.
• Idempotent event processing: Deduplication logic to prevent double-counting bounces, duplicate suppression entries, and corrupted delivery metrics.
• Cross-provider event normalization: Adapter pattern to convert provider-specific webhook payloads into a consistent internal format for agnostic business logic.
• Use Case: If you run a SaaS platform that sends 10,000+ transactional emails monthly, use this skill to build a webhook endpoint that automatically suppresses hard bounces and spam complaints to protect your sender reputation and reduce wasted send volume.

Quick Start

Use the webhook-processing skill to build a secure Resend webhook endpoint that automatically adds hard bounce recipients to your tenant-scoped suppression list.
