To securely process inbound emails with an AI agent using webhooks, configure Resend webhooks for real-time notifications and apply multi-layered security including sender allowlisting, content sanitization, and human-in-the-loop verification to prevent untrusted input injection.

The best way to prevent prompt injection from email replies is to implement content sanitization that strips quoted reply threads, combined with sender allowlisting to ensure the AI agent only processes trusted input.

Yes, you need a webhook secret to receive emails through Resend for your agent. You must set the RESEND_API_KEY and RESEND_WEBHOOK_SECRET environment variables to validate incoming webhook signatures and ensure secure event-driven email processing.

Yes, you can require human approval for sensitive actions triggered by inbound emails. The system supports human-in-the-loop verification as a configurable security layer to protect your AI workflows from executing unauthorized or malicious commands.

Event-driven email receiving works without polling by using Resend webhooks to push instant notifications to your AI agent. This architecture facilitates real-time responsiveness and eliminates the latency and resource overhead associated with continuously checking an inbox.

When filtering untrusted email content for AI processing, limitations depend on your configured security layers. While content sanitization and strict sender allowlists mitigate risks, complex prompt injection attempts may still require human-in-the-loop verification to fully secure sensitive actions.
