Inbox Zero
What is Inbox Zero?
Inbox Zero connects to Gmail or Outlook and uses AI to label incoming mail, draft replies in your voice, and surface what needs attention first. You get pre-written responses waiting when you open your inbox, plus bulk unsubscribe tools for newsletters you never read. The product works on web, iOS, Android, Slack, and Telegram so you can triage mail without living in your email tab.
Most email assistants stop at summarization. Inbox Zero also blocks cold emails, files attachments automatically on higher tiers, and pulls calendar and CRM context into drafts so scheduling replies match your real availability. The codebase is open source with 9k GitHub stars, SOC 2 Type 2 certification, and a self-host option for teams that want full control.
Starter plans cover solo operators who want labels, analytics, and reply drafts. Plus adds Slack, Notion, Stripe integrations, and an unlimited knowledge base. Professional adds team analytics and dedicated onboarding. Over 20,000 professionals use Inbox Zero, and every paid plan includes a 7-day free trial.
Superhuman
What is Superhuman?
Superhuman Mail is an email assistant built for people who live in Gmail or Outlook and want to move faster. Split Inbox separates team, VIP, and tool notifications so urgent threads surface first. AI drafts replies in your voice, schedules follow-up reminders, and shares live email views with teammates who can comment without forwarding chains.
Gmail adds features slowly and Outlook optimizes for enterprises, not speed. Superhuman Mail targets keyboard-first workflows with read statuses, snippet macros, autocorrect tuned for email, and collision detection when two teammates reply at once. The broader Superhuman suite now bundles Grammarly, Docs, and the Go AI agent, but Mail remains the piece that promises to save about four hours per person each week.
Sales teams, founders, and customer success groups on Business plans get Mail alongside CRM sidebar integrations for HubSpot, Salesforce, and Pipedrive. Free and Pro tiers cover writing and docs tools only; Mail unlocks at the Business plan level.
