Zirbe is an email app that looks and feels like a texting app while keeping real email underneath. A conversation in Zirbe is a mail thread, not a person: the subject is the title, the people on it are the members, and every message is a bubble in time order. The same person writing you about five different things becomes five conversations, which is how email actually works. Starting a new conversation means naming it, and that name is the subject. Underneath the chat is a full email client. Read and reply with bubbles, attach photos, files, or a recorded voice message, and open what you receive in a full preview to save or share it. Reach every folder, not just the inbox: archive, move, and organize, save and resume drafts, and send blind copies that stay blind. React to a message with a tapback that rides your own mail as a real reply, so another Zirbe user sees the badge and every other mail app sees a readable line. Search within a conversation, pin the threads that matter to the top, and block a sender to sweep their mail to Junk and keep it there. New mail arrives with a local notification and a badge, and a reply that fails to send waits as a tap-to-retry bubble instead of vanishing. Sender photos come from your own contacts, and typing a recipient suggests people from your address book. Zirbe is private by construction, not by promise. It connects only to your own IMAP and SMTP servers over an encrypted connection. There is no Zirbe server, no account to create with us, no analytics, no telemetry, and no third-party SDK. Your mail is cached on your device so the inbox opens instantly and works offline; your password lives in the device Keychain and is never synced off the device. Remote images in HTML mail are blocked until you choose to load them, so opening a message never phones home. Because the whole app is open source, every one of these claims is something you can check for yourself. Zirbe works with any email provider that supports standard IMAP and SMTP with an app-specific password. Sign in with your address and an app password, and if your provider is a common one the server settings fill in for you. Zirbe is free and MIT-licensed. It is an independent app and is not affiliated with or endorsed by Apple. iMessage and Messages are trademarks of Apple Inc.
