Macro Mail is an email client built around the opinion that your inbox shouldn't be separate from your tasks, conversations, and AI tools. Unlike Superhuman, It pulls email, chat, tasks, and AI agents into a single shared workspace while still being designed for people who spend a significant chunk of their day in their inbox and want to move fast.

The keyboard-first design is central to how it works. You can navigate, triage, and act on messages without touching the mouse, which adds up over a full workday.

Key capabilities include:

• @mention anything: people, docs, tasks, channels can be referenced in email and opened in the Macro ecosystem.
• Keyboard Shortcuts: navigate, mark as done, or search through everything all from the keyboard.
• Built-in chat: all communication in one place so there is no switching between email and a separate messaging tool
• Task management: tied directly to the inbox for creating actionable items straight from email.
• AI agents: that can take actions inside the workspace whether it be email drafting, automations, tag labeling, etc.

Macro Mail is aimed at professionals and teams who find standard email clients too passive. If you're already using tools like Inbox Zero for triage or exploring AI agent-based email handling, Macro Mail positions itself as an all-in-one alternative that keeps everything in one place.

The AI layer is woven into drafting, summarization, and agent actions throughout the product. That makes it a different category from clients that add AI as a plugin or optional add-on.
