Email capabilities designed around agent work.
Each capability starts with a concrete agent task: acquire an inbox, wait for a code, search a thread, react to new mail, or own the infrastructure.
mails0 combines programmable inbox primitives with agent-native interfaces. Use the hosted sandbox to validate a workflow quickly, then keep the same CLI, HTTP, Python, or MCP model when you move to a permanent mailbox or your own Cloudflare deployment.
Choose the capability your workflow needs now
Start with the smallest useful surface. A testing agent may only need a temporary inbox and code extraction; a production system may need persistent identities, events, domains, and storage control.
Agent mailboxes
Give AI agents scoped email identities with automatic temporary inboxes, permanent claimed mailboxes, mailbox-level keys, expiry, and self-hosted domains.
Open feature →Verification-code extraction
Let agents wait for and extract email verification codes through CLI, HTTP, Python, or MCP, with mailbox scoping and multilingual code parsing.
Open feature →Email MCP server
Connect Claude, Codex, Cursor, Windsurf, and other MCP clients to scoped email tools for inboxes, search, codes, threads, attachments, and sending.
Open feature →Inbox search and threads
Give agents searchable email history with inbox filters, automatic labels, message retrieval, thread reconstruction, attachments, and structured extraction.
Open feature →Webhooks and events
React to inbound email and delivery state through signed webhooks and server-sent events, with retries, idempotency, scoped routes, and audit-friendly payloads.
Open feature →Cloudflare self-hosting
Run agent email on Cloudflare Workers, D1, R2, and Email Routing with your own domain, sender provider, data controls, quotas, and operational ownership.
Open feature →Attachments and extraction
Retrieve email attachments, metadata, verification codes, links, headers, and structured message fields through scoped APIs built for agent workflows.
Open feature →Permissions and lifecycle
Control temporary and permanent agent mailboxes with scoped keys, receive-only defaults, expiry, pause, rotation, claims, and self-hosted policy.
Open feature →Start with one bounded email capability.
The fastest validation is a temporary inbox plus one real inbound message. Add sending, persistence, and automation only when the use case requires them.
