Beyond Sluggish Email Clients:
Fast, Native, Unified Communications for Mac
Outlook for Mac is notoriously slow and bloated. Modern work happens across email, Slack, GitHub, and messaging.
HeyRobyn brings everything into one lightning-fast, Mac-native inbox with AI triage and zero Microsoft telemetry.
100% local-first. No Microsoft cloud lock-in. Built for keyboard power users on Mac.
Why Mac Users Are Leaving Outlook
Actually Native for Mac
Outlook for Mac is a sluggish web wrapper with poor macOS integration. HeyRobyn is built with Swift + AppKit—launches instantly, uses 70% less RAM, respects every Mac convention.
Unified Communications, Not Just Email
Outlook handles email and calendar. HeyRobyn unifies email + Slack + GitHub + WhatsApp + Telegram + iMessage in one AI-powered inbox—no more app switching.
Zero Microsoft Telemetry
Outlook sends usage data to Microsoft servers. HeyRobyn stores nothing in the cloud—ever. All messages encrypted locally on your Mac. No tracking, no telemetry, no cloud lock-in.
AI Triage Across Platforms
Outlook's Focused Inbox only sorts email. HeyRobyn's AI understands context across platforms—auto-prioritizing urgent Slack DMs, critical GitHub PRs, and VIP emails together.
Keyboard-First Design
Tired of Outlook's clunky shortcuts? HeyRobyn offers Vim-style navigation, fully customizable bindings, and a Cmd+K command palette for every action across all platforms.
No Exchange Server Required
Works with any email provider (Gmail, iCloud, Fastmail, ProtonMail, custom IMAP). Break free from Microsoft's ecosystem without losing functionality.

Questions from Outlook Users
Can HeyRobyn work with my company's Exchange Server or Microsoft 365 account?
Yes, but with limitations. HeyRobyn supports Exchange via standard IMAP/OAuth, so basic email and calendar work fine. However, advanced Exchange features (shared calendars, room booking, free/busy scheduling, Teams integration) require Outlook. If you're in a heavy Microsoft enterprise environment, Outlook may still be required for work while HeyRobyn handles your personal workflows.
Why is Outlook for Mac so slow compared to Windows?
Outlook for Mac is built using web technologies (Electron-style wrapper) rather than native macOS frameworks. This causes slow startup, high memory usage (1-2GB+), and poor integration with macOS features. HeyRobyn is built with Swift + AppKit—the same frameworks as native Mac apps—resulting in instant launch, 70% less RAM, and proper macOS integration.
Can I migrate my Outlook emails, contacts, and calendar to HeyRobyn?
Yes! If you use IMAP-based email (Gmail, iCloud, most providers), just reconnect your accounts and everything syncs automatically. For Exchange accounts, HeyRobyn uses standard protocols so your mail, contacts, and calendar transfer seamlessly. We provide a migration guide for Outlook users to help with the transition.
Does HeyRobyn work with non-Microsoft email providers?
Absolutely! HeyRobyn works with Gmail, iCloud Mail, Fastmail, ProtonMail, Zoho, and any IMAP/CalDAV provider. Unlike Outlook, which pushes you toward Microsoft 365, HeyRobyn is provider-agnostic and privacy-focused—you control where your data lives.
What about Microsoft Teams integration?
HeyRobyn doesn't integrate with Teams (that's Outlook's domain). However, if your team uses Slack, Discord, or other modern chat platforms, HeyRobyn unifies those with email, GitHub, and messaging. If you're locked into Teams at work, you may need to use both—but HeyRobyn can handle your personal Slack workspaces, side projects, and freelance communication.
Is HeyRobyn really more private than Outlook?
Yes. Outlook sends telemetry and usage data to Microsoft servers and requires cloud sync for many features. HeyRobyn stores nothing in the cloud—ever. All messages are encrypted locally using macOS Keychain, AI runs on-device using Apple's Neural Engine, and we send zero telemetry. We're also planning to open-source the core so you can audit the code yourself.
Does HeyRobyn support Outlook's rules and automation?
Yes! HeyRobyn has a powerful automation system with rules, filters, and webhook support that works across email, Slack, GitHub, and messaging. Unlike Outlook's email-only rules, HeyRobyn's automation spans all platforms—auto-archive GitHub notifications after 7 days, forward urgent Slack DMs to email, snooze non-critical messages, and more.
Can I use HeyRobyn alongside Outlook for work requirements?
Yes, many users do this. Keep Outlook for work email/calendar/Teams (if required by IT), and use HeyRobyn for personal email, side projects, freelance work, and unified communications (Slack, GitHub, WhatsApp, Telegram). HeyRobyn won't interfere with Outlook—they can run side-by-side on your Mac.
