Mailspring vs Spark Mail Comments
As far as my usage history, the best alternative for spark mail is Mailspring in terms of UI and UX. Though it lacks some features I use Mailspring as my daily driver.
It's the most similar, with the features most inline. It even looks the same in appearance, and all the menus and shortcut keys match.

- Mailspring is Freemium and Open Source
- Mailspring is Customizable



















I tested it, generally it is ok, but it sometimes does not show new arrivals at the top of the list, even though the counter increases. However, good mail client, which does not need any clumsy registrations somewhere.
