Agent-native email & calendar

Your inbox and calendar —
run by your agent, owned by you.

One account your agent can drive end-to-end — and a calm, sorted inbox for you.

Three things need you today. The DPA is the urgent one — I blocked 16:00 and sent the invite.

one command, and your agent has an inbox

The MCP surface

One excellent MCP server.

Your agent talks to one server for email and calendar — not a drawer of brittle plugins. It's built for how agents actually work:

Light on tokens

Compact responses, so your agent spends far fewer tokens per task. Cheaper to run, and more room left in its context for the real work.

Safe by default

Your mail is treated as data, never as commands — so a buried instruction in an email can't turn your agent against you.

OAuth, not your password

Each MCP client connects through an OAuth grant you approve — your agent never sees or stores your password.

No lock-in

Bring your Gmail. Keep your apps.

Bring your Gmail — it stays in sync

Connect your existing Gmail and new mail keeps flowing into your sovereign mailbox. Your to-dos and archiving mirror back to Gmail, so both stay in step — move over at your own pace, nothing to rip out.

Keep the email app you already use

Anything that speaks IMAP connects with an app password. Langmail is a mailbox, not a walled garden.

NOT TRAINING SIGNAL

your mail feeds no model

Every layer is an open protocol, so the right to leave is built in. We'd rather you stayed because it's good.

The human half

Your agent does the operating. You get the calm.

One brief a day

A single calm email each morning — what was handled overnight, what needs you, what's on the calendar. In your language.

Sorted before you look

Every mail lands classified — to-do, calendar, FYI, done — so the inbox reads like a checklist, not a pile.

Only what needs you

Choose the clean-inbox style and routine mail is summarized and archived once handled. What stays in view actually needs a human.

The community

Build in the open, with people who care.

Trade agent recipes, help shape the roadmap, and get a hand wiring your inbox to an agent. Our Discord is where the Langmail community lives.
