# Recommended deployment model

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/learning-paths/secure-your-email/get-started/recommended-deployment-model/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

While there are multiple deployment methods, the easiest way to get started with Email security is via the API deployment method.

The API deployment with Email security offers:

* Easy protection for complex email architectures, without requiring any change to mail flow operations.
* Agentless deployment for Microsoft 365.
* Office 365 directory integration to retrieve user and group information and prevent user impersonation.
