namailu.cz

namailu.cz gives AI agents their own real email inboxes, so they can read and send mail without being handed the keys to yours.

Each agent gets a dedicated address — on namailu.cz or on your own domain. You decide which inboxes an agent may touch, and every grant can be paused or revoked on its own without affecting the others.

The connector exposes seven tools:

• List the inboxes an agent is authorised to use
• List messages as metadata only — reading the list never marks anything as read
• Read one message, with its body returned as untrusted content and attachments listed

as metadata rather than raw bytes

• Send mail, with attachments — up to 10 files and 10 MiB per message, delivered as

the original bytes rather than re-encoded, and scanned before they leave

• A health check that returns no tenant, mailbox or message data

Reading message content requires a separate scope from listing inboxes, so an agent that only needs to know what arrived never gets permission to read it.

Sending is marked destructive, so Claude asks before every send. Message content is treated as untrusted input throughout: an email that contains instructions is data, never an authorisation to call another tool.

The portal, sign-in, documentation and support are available in Czech and English. The service runs on our own infrastructure in the European Union and is operated by DW Technology LLC.
