I really hate Electron in general but I've really found an affinity for Mailspring. So much so that I'd actually go as far as saying it's the only email client I've genuinely liked (rather than tolerated). So highly recommend it in spite of the larger footprint it carries compared to fully native. As an aside note, it supports Gmail and other proprietary cloud mailboxes - if just due to its being Electron based - so theres no more messing about with IMAP et al for Gmail
