Mimestream 1.1.3 – A native macOS email client for Gmail.

Mimestream combines your favorite Gmail features with the power of a native macOS app so you can move through your email effortlessly

Made for Mac, optimized for Gmail

As a native app written in Swift, Mimestream leverages the full power of macOS to deliver a lightning-fast and instantly familiar experience. Instead of using the IMAP protocol, Mimestream utilizes the Gmail API to enable an enhanced set of features that let you work with ease.

Your data and credentials are stored only on your device, and the app only makes direct connections to Gmail. There are no intermediary servers, and Mimestream does not collect or sell your email.
