Two philosophies. Superhuman replaces your email client with a fast, keyboard-driven one — you change how you work. SaneBox changes nothing visible: it filters low-priority mail into SaneLater inside whatever client you already use. Adoption risk is the real difference: teams abandon new clients; a filter that quietly works has nothing to abandon. If you love tooling and live in email hours a day, Superhuman's speed compounds. If you just want fewer things screaming at you, SaneBox is the lower-friction fix — and the cheaper one.
SaneBox in short
AI email triage that works on top of any provider (Gmail, Outlook, IMAP) — filtering low-priority mail into a SaneLater folder so the inbox holds only what needs attention. Paid plans by feature tier (folders, reminders, do-not-disturb).
Verdict
Match the tool to the job above — and if you're still unsure, run both free tiers against one real week of work. That answers it faster than any review.
