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

When you choose the [API deployment](https://developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/api/), Email Security can both scan and take actions on emails after they have reached a user's inbox.

With a [Journaling setup](https://developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/bcc-journaling/journaling-setup/m365-journaling/) alone without API integration, Email Security can only scan emails after it has reached a user's inbox.
