Does my AI agent need a preexisting Gmail or Outlook account to use this?

No. AgentMail is entirely standalone. You can use your agent to programmatically provision brand new, unique email addresses in seconds, completely independent of legacy email providers.

Can my agent download files that users send to its email address?

Yes. When scanning threads in the inbox, your agent will detect any attached files. It can then use the dedicated attachments tool to retrieve and analyze the contents of the file before drafting a reply.

Is it possible to manage multiple outreach campaigns at the same time?

Absolutely. Your agent can create and manage multiple inboxes simultaneously. It can list all active boxes, read unread threads for each, and contextualize its replies based on the specific campaign inbox.
