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.
superReply

What is superReply?
superReply is a Chrome extension that drafts AI email replies inside Gmail and Outlook web inboxes. One click surfaces multiple tone-matched response options so you can answer customer care or sales threads without writing from scratch. The free tier covers up to 90 AI-powered replies each month.
Compared with standalone copy tools, superReply lives in the inbox and also lists integrations for WhatsApp, Slack, LinkedIn, Upwork, and Fiverr alongside Gmail and Outlook. Paid plans unlock unlimited replies and advanced tone controls, while the extension only reads messages you explicitly run it on and does not store automated responses on superReply servers.
Support reps, agency freelancers, and founders answering high-volume inboxes use it to clear routine threads faster. It fits teams that want personalized reply suggestions per user rather than a shared bot account, because each person installs the extension with their own login.
