You already know who gets answered in an hour and who waits a week. You already know which newsletters you never read. But no tool has ever said, quietly, "great, I'll handle it." So the person you answer fastest still waits for you to type, and the mail you never wanted still gets looked at.
HandledInbox reads how you already handle email, then takes over the repeatable part, under rules you set and can see. It sorts everyone who mails you into a small set of groups. For each group you grant exactly one permission:
Drafts land in your own mail client. Approval is pressing Send. There is no new app to live in, and nothing escalates on its own.
It writes replies to messages you already answered, then compares its version against what you actually wrote. Blind judges saw both and picked the human one.
65% of real replies have no greeting line at all. Every other AI staples "Hey Kim," onto everything, and that is exactly how you spot the fake. This one measures who you greet, and how, per person, and matches it.
When you connect, the first thing you do is name your handler. Marlowe signs only what it says as itself: the daily digest, the occasional question. It never signs the drafts; those are your voice. It never pretends to be human. Staff, not mascot.
Three drafts are waiting. Twelve senders went to the batch. One question when you have a minute: should invoices from Delgado & Sons go to Alex directly?
The groups come from two things it measures separately: how fast you already reply to someone, which sets the action, and how you already greet them, which sets the voice. Never blended into one importance score, because a CEO is often formal and fast, and that is the exact person a one-dimensional list destroys.
Works with Gmail today; a mailbox connects in under two seconds. Microsoft 365 is on the roadmap, not available yet. Six mailboxes run live today on the founder's own mail.
