SuperMailbox

SuperMailbox brings your Gmail, Outlook, iCloud Mail, Yahoo Mail, Fastmail and other IMAP mailboxes together for your AI assistant. Connect Gmail and Outlook with OAuth, and iCloud Mail, Yahoo Mail, Fastmail or other IMAP accounts with provider-supported credentials. Search across connected mailboxes, including semantic search for relevant messages, and read messages and threads. Search may use cached and indexed mail alongside provider results; results can be incomplete or not yet fresh. Fetch attachments on request, manage read state and stars, archive or move messages, create unsent drafts, and send, reply or forward when requested. SuperMailbox rules run on new incoming messages after they arrive: conditions match sender, recipient and/or subject; actions move a message to a folder, Trash or Junk, or add an existing Gmail label where supported. Rules are managed through SuperMailbox and do not change provider-native filters, act on historical mail, send or forward mail, or permanently delete messages. Access is limited to mailboxes connected to the authenticated SuperMailbox account. Read, attachment, draft, send and mailbox-change permissions are separate. Available actions vary by provider capabilities and account access.
