About Sickle
Sickle is a native macOS mail client for every account you own: Gmail and Outlook over OAuth, iCloud, Fastmail, Yahoo and any IMAP server. No cap on accounts, a colour per mailbox, an email cleaner for one-time codes and subscription junk, and keyboard/Vim navigation. It also runs a remote MCP server, so Claude, Cursor, Codex or OpenClaw can search, read, archive, draft and send across all of them, with read, change and send granted and revoked separately. One subscription, 30 days free.
The Mac app
Each opens full size: 2× PNGs of a 1440 × 900 window, with its shadow. Versions without the shadow are in the zip.
Video
A 50-second silent walkthrough: a conversation and its attachment, switching accounts, the email cleaner and account colours.
Logos
The app icon, on its own and on white, and the mark. Smaller icon sizes are in the zip.
