MonsterMailbox

Monster Mailbox is your AI mail crew. Agents will be able to triage every message, hold the suspicious ones, and review every send before it leaves your outbox. Built for people who'd rather not babysit a Gmail tab. Or give your agent access to anything sensitive. WHAT YOU GET โ€” Smart Inbox triage. Each message lands in Trusted, Held, or Rejected based on signals your agents learn over time. You only see the mail that actually deserves your attention. โ€” Outbox approvals. Every outbound message gets a quick second look. Suspicious link in a draft? Caught before it sends. Wrong recipient? Flagged. โ€” AI agents per address. Spin up dedicated assistants for sales@, support@, hello@, or anything else. Pause and resume them from one screen. โ€” Push notifications you actually want. Priority mail only, not the firehose. โ€” Native iOS, built in Flutter. Cold-launches fast, works offline-first for triage decisions. WHO IT'S FOR โ€” Solo founders and operators drowning in inbound. โ€” Engineers who want their mail in plain text and their automations transparent. โ€” Anyone who's been burned by a "Reply All" they couldn't take back. HOW IT WORKS Connect a Monster Mailbox address (or several). Your agents do the heavy lifting โ€” quarantine, classification, draft replies, send approvals. You stay in the loop without staying in your inbox. PRIVACY Your mail is yours. Agents run against your account on your terms. See monstermailbox.com/privacy for the full policy.
