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.

Requires macOS 11 Big Sur or later. Free during beta.

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.
