What Mimestream is — and where it stops
Mimestream is a fast, native macOS client for Gmail that power users love. It's a great client — but it's Mac-only, Gmail-only, and it doesn't bring AI triage, drafting, or security.
Where teams outgrow Mimestream:
- Mac-only and Gmail-only.
- No AI triage or auto-filing to a Later folder.
- No AI drafting or inbox Q&A.
- No fraud/phishing quarantine.
Why Inbox Hero is the Mimestream alternative people switch to
Inbox Hero isn't just a filter or a cleanup tool — it's an AI that runs your inbox end to end:
- AI auto-filing (Later): bulk mail, newsletters, receipts and notifications move out of your inbox into an Inbox Hero/Later folder automatically — the SaneBox idea, done with AI. Every move is one-tap undoable and it learns from your corrections.
- Ask your inbox: "What am I waiting on?", "Did the contract land?" — ask in plain English and the AI reads your mail and answers.
- Quick Reply: Inbox Hero drafts replies in your voice; glance, tweak, and send with a swipe.
- Fraud & phishing protection: an optional scanner reads incoming links and messages and quarantines phishing, scams and malware into a dedicated Fraud folder — a security layer none of the folder-only tools offer.
- Custom folders: route any sender or keyword into a folder you choose; your rules always win.
- Works everywhere: Gmail via Google, plus iCloud, Yahoo, Fastmail and other IMAP mailboxes with an app password (Outlook.com is not supported yet).
