> Their title on HN and website is "A native macOS email client for Gmail," and that's exactly what it is, especially if you were trying to be technical.

"Email client" used to mean something before everyone started assuming Email = Gmail.

Imagine someone submitting a link posted as "A web-browser for facebook.com".

Nobody here would ever accept that a piece of software which could only work on facebook.com to be an actual web-browser.

So why should we allow for the same exception when it comes to email?
