Mailtwine
AI triage that sorts, drafts, and routes your existing inbox, surfacing only what needs you.
Mailtwine runs behind the Gmail, Outlook, Fastmail, or Helpmonks account you already use — no migration, no new address — sorting incoming mail, drafting replies, routing requests, and handling approved routine work automatically, then surfacing only the decisions that still need a human. A Chrome extension puts reply suggestions, related past threads, and a thread briefing beside the conversation in your existing inbox. It connects via OAuth, Fastmail JMAP, Helpmonks' API, or plain IMAP/SMTP.
