Mailows

Mailows is email for your AI. It gives your AI assistant its own email inbox, so it can read incoming mail, reply and send messages with attachments — without access to your personal mailbox.

Each agent gets a dedicated address 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 app 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; attachments can be read too — text and images directly, other files such as PDF through a one-time download link for your sandbox, if the mailbox owner allows it
• Prepare and upload attachments for sending, as the original bytes
• Send mail with up to 10 files and 10 MiB per message, scanned before they leave
• A health check that returns no tenant, mailbox or message data

Reading message content requires a separate permission from listing inboxes, so an agent that only needs to know what arrived never gets permission to read it. Sending has to be granted deliberately and is marked destructive, so you are asked 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 service runs on our own infrastructure in the European Union. Mailows is operated by DW Technology LLC.
