Multi-Domain Mailboxes
Manage all your domains, brands, and mailboxes from a single self-hosted app. Unify communication with total data ownership.

Broadcasts

Email API
A small, versioned HTTP API for sending, listing, reading, replying, forwarding, and transferring attachments — hosted on your deployment.
AI Agents
Let agents send and receive email over a clean, predictable HTTP API — ideal for automated workflows, tool use, and human-in-the-loop email.
Team & Permissions
Invite teammates and control exactly which domains and mailboxes each can access. Clear roles, clean boundaries — no guesswork.
Email for the agent era
Your AI agent can chat.Now give it an inbox.
Give AI agents a real business address they can read and reply from. MarkRelay provides a scoped API, signed webhooks, and an installable Agent Skill—all in your Cloudflare account.
