Mailbird Next is a desktop email client for Windows and Mac, rebuilt on one codebase so it is the same app on both. Every account in one unified inbox, native calendar and contacts, and apps like WhatsApp and Asana in a panel beside your mail. Privacy Hub blocks trackers and remote images. An MCP server lets you connect Claude, ChatGPT or Cursor to your inbox; off by default, your mail stays on your computer. Free for one account, no time limit. Android app in beta now, iPhone coming soon.
