Email Clients

Kanmail is an open-source desktop email client that reframes your inbox as a kanban board: each column is a mailbox or folder, and you drag messages between columns to file, archive, or triage them. It runs locally on your own machine and connects straight to your existing accounts over IMAP/SMTP, including Gmail. Because it is a native desktop app rather than a hosted service, your mail stays between your computer and your mail provider, with no third-party inbox sync in between. It suits people who process a high volume of email and prefer a visual, drag-and-drop workflow to a traditional list view.

✦ Best for heavy email users wanting drag-and-drop inbox triage
