# BCC/Journaling

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/bcc-journaling/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

BCC/Journaling deployment is a post-delivery type of deployment. Cloudflare analyzes emails after they reach the user's inbox. Every time you receive an email, your email provider will send a blind copy to Cloudflare for an analysis.

* Choose [BCC](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/bcc-journaling/bcc-setup/gmail-bcc-setup/gmail-bcc-setup/) if your email provider is Gmail.
* Choose [Journaling](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/bcc-journaling/journaling-setup/m365-journaling/) if your email provider is Microsoft 365.
