        "longDescription": "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 \u2014 without access to your personal mailbox.\n\nEach 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.\n\nThe app exposes seven tools:\n\n\u2022 List the inboxes an agent is authorised to use\n\u2022 List messages as metadata only \u2014 reading the list never marks anything as read\n\u2022 Read one message, with its body returned as untrusted content; attachments can be read too \u2014 text and images directly, other files such as PDF through a one-time download link for your sandbox, if the mailbox owner allows it\n\u2022 Prepare and upload attachments for sending, as the original bytes\n\u2022 Send mail with up to 10 files and 10 MiB per message, scanned before they leave\n\u2022 A health check that returns no tenant, mailbox or message data\n\nReading 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.\n\nMessage content is treated as untrusted input throughout: an email that contains instructions is data, never an authorisation to call another tool.\n\nThe service runs on our own infrastructure in the European Union. Mailows is operated by DW Technology LLC.",
