It brings Gmail, iCloud, Outlook, Microsoft 365, Yahoo and other IMAP accounts together in one unified inbox, with a clean interface, light and dark modes, and support for multiple Macs under one license. Designed for macOS 14 and later, the app offers fast account-wide search, conversation-style threads, instant IMAP delivery, smart inbox tabs, snoozing, scheduled sending, reminders and rules for organizing incoming mail. Users can compose rich-text messages, manage aliases and signatures, work with attachments, and respond to calendar invitations.

Privacy is central to the product: messages travel directly from the email provider to the Mac, and bytemail says it does not see or store users’ mail. Search indexes and features such as summaries and rewriting run on-device; tracking pixels are removed before messages are displayed. Additional tools include one-click unsubscribe, sender warnings, undo send, spam reporting and blocking.

bytemail offers a seven-day free trial, followed by monthly or yearly subscriptions, as well as a lifetime purchase option
