For years, I've been using the Mail app on the Mac to manage my personal (iCloud) and work (Gmail) email. But Mail hasn't been optimised for Gmail users and it never will be.
Then, my colleague recommended I check out Mimestream; a Mac OS email client built specifically for Gmail users. It's been designed with a similar minimal design to Apple Mail but it's been optimised to work well with Gmail accounts. The founder, Neil Jhaveri has over 13 years of experience working on email products. Before founding Mimestream, he was a software engineer at Apple for 7½ years, leading and managing engineering teams working on Mail and Notes.
I've been enjoying Mimestream for the last few months and have found it's really improved my email efficiency. Check it out here!
