Inbox Imp is an AI email organizer for Gmail and Outlook. It reads your mail so you don't have to: anything that needs a reply stays in your inbox, and everything else is filed where you can still search it. Nothing is deleted behind your back. An AI assistant sorts every incoming email: advertising gets filed, cold pitches go to their own pile, and the handful of messages that actually need you stay in a short, quiet queue. The app shows you that queue: who wrote, what it's about, and why it's worth your time. Clear each message with one swipe. Every inbox you own, one membership. Connect Gmail, Google Workspace, Outlook.com, Hotmail and Microsoft 365 addresses under one account. - Rules you can read: a plain-English page says how your mail is handled, and you can edit it - Safeguards above the AI: login codes, real replies, receipts and money mail, calendar invites and account notices stay in your inbox - Archive, never delete: filed mail stays searchable; only clear junk goes to Trash, recoverable for 30 days - Every action is logged with a reason, one tap to undo, and a Recently archived list to review - "Why you got this" on every message it keeps - Reply, forward and compose with dictation, attachments and AI drafting help - Catch up on a long thread in one line per message - Push roundups instead of a ping for every email; urgent mail still comes through - Ask your mail anything: search that answers questions, not just keywords - Spending: what you paid, by merchant, from your receipts Independently security reviewed: Inbox Imp passed Google's OAuth verification with a CASA Tier 2 assessment, renewed yearly. Try Inbox Imp free for 7 days; no payment details needed to start. After the trial, an Inbox Imp membership is $9.99 per month (auto-renewing, cancel anytime in Settings) and covers all of your inboxes.
