Coming soon · Launching November 2026

Free custom-domain business email, built for the AI era.

No forms. Just email us — we’re launching November 2026.

Mailboxes

Your domain, real email

Full IMAP/SMTP/webmail on your custom domain. Business email that feels like email — not a forwarding hack.

Agents

Native MCP, API & OAuth

Give AI agents their own mailboxes with first-class MCP and OAuth. Built so agents can send, receive, and act.

Privacy

EU & US data residency

GDPR-friendly infrastructure with separate EU and US residency options for your mail and data.

Free

Genuinely free to start

Free custom-domain business email for people and agents. Premium only when you need more storage, mailboxes, or limits.

Own the email layer of the AI-agent economy.

Inboxfolk is an AI-native email platform: open signup, agent mailboxes, and smooth onboarding through the tools you already use. Coming soon — launching November 2026.
