One email layer, shaped for different builders.
The same mailbox primitives support autonomous agents, coding copilots, test suites, browser flows, and teams that need to own their deployment.
mails0 is built for software-driven email workflows rather than human newsletter or support operations. Each audience page maps the same secure primitives to a different job, success event, integration path, and operating boundary.
Find the workflow closest to yours
Audience pages focus on the complete job: what triggers the email, what the agent must retrieve, where credentials live, and what should remain under human control.
AI agents
Give autonomous and supervised AI agents scoped inbox identities, OTP retrieval, search, threads, events, and optional sending without human mailbox access.
Open workflow →Coding agents
Give Claude Code, Codex, Cursor, Windsurf, and terminal agents a scoped inbox for signup flows, OTP codes, notifications, and integration testing.
Open workflow →QA engineers
Test signup, password reset, invitations, receipts, and OTP flows with isolated inboxes, explicit waits, message assertions, and CI-friendly APIs.
Open workflow →Browser automation
Complete browser signup, confirmation, invitation, and OTP flows with an isolated agent inbox, explicit waits, secure code retrieval, and Playwright support.
Open workflow →Cloudflare developers
Build and self-host agent inboxes with Workers, D1, R2, Email Routing, custom domains, signed webhooks, scoped credentials, and configurable limits.
Open workflow →Open-source teams
Audit, extend, and self-host an MIT-licensed agent email stack with explicit data ownership, portable interfaces, scoped credentials, and Cloudflare deployment.
Open workflow →Platform engineers
Give internal agents and test systems a governed email layer with Cloudflare deployment, scoped credentials, webhooks, retention, and observable lifecycle controls.
Open workflow →Startup teams
Validate AI agent email workflows quickly, then choose hosted sandbox, self-hosting, or a managed provider based on traction, risk, and operating capacity.
Open workflow →Map one user journey before adding more infrastructure.
Choose the page that matches the operator and automate one full loop from mailbox creation to a verified result.
