I switched to Mailspring a year or two ago and am very happy about it. It's based on electron so here be dragons, but does the job quite well. It's simple and basic and no fuss while not being an eyesore. Basically, a clone of the Mail app on macOS.
I've tried to use Mailspring a couple of times on Linux but apparently server syncing is still broken after 5+ years[0]. Until it works reliably I'm stuck with Thunderbird.
