A browser inbox for your domains’ mail
Threads, labels, search, attachments, compose, scheduled sends, spam controls, and a Sent view. Successful developer API sends also get mailbox copies. Outbound mail uses Cloudflare Email Service, which Cloudflare’s terms cover for transactional sending; confirm with Cloudflare before relying on it for everyday conversational replies. You can add domains after setup, review their DNS, and create personal, role, agent, or disposable addresses.
Transactional email for applications
Use domain-scoped API keys, idempotent requests, reusable templates, delivery timelines, suppressions, and signed webhooks. Optional open and click tracking starts off. Logs show individual message events; Box Ox does not include an aggregate mail-performance dashboard.
Agent access with boundaries
The remote MCP endpoint runs on your Worker. OAuth approval, mailbox grants, sending caps, and revocation control what each agent can do. The downloadable CLI and email skill help agents integrate your applications. Mail MCP access does not grant Cloudflare account administration.
Processing stays your choice
Local filters, reputation checks, and AI are separate settings. AI remains off until you choose it. External providers receive selected content when enabled. Read the data-flow details.
