Going through all the emails you receive in one day and keeping your inbox clean can take a lot of effort, especially if you don’t have a sorting system.
Spark is an email client that helps you manage multiple accounts and offers you the option to keep messages organized by category.
Thanks to the integrated Smart Inboxes, within Spark you get to view the urgent messages on top, and receive notifications only for the critical emails.
Airmail 5 is a new mail client designed with performance and intuitive interaction in mind optimized for macOS High Sierra! Support for iCloud™, MS Exchange, Gmail™, Google™ Apps, IMAP, POP3, Yahoo!™, AOL™, Outlook.com™, Live.com™
Email clients that support Gmail aren't exactly rare, but the vast majority of them use the IMAP protocol to retrieve and manage your messages, which means they can't take advantage of Gmail-specific features such as inbox categorization, labels, and synchronized signatures.
Mimestream goes about it differently — it uses the Gmail API, allowing it to provide most, though not quite all, of the features you are familiar with from Google's mail client. It's also worth noting that the app is written in Swift, so it will integrate very well with macOS and provide a much smoother experience than, for instance, an Electron-based app.
Postbox 7 is a new email application that helps you organize your work life and get stuff done. It has all the elegance and simplicity of Apple Mail, but with more power and flexibility to manage even the most demanding workloads.
