Sparrow has been dead for over 5 years so not exactly a modern thing, it was apple only, not cross platform anyways so not comparable to thunderbird. Airmail is also apple only so useless to most people. Mailbox was a phone only app that stopped operating last year, again not a cross platform desktop client. You're welcome to try again, but AFAIK there are no such "modern" cross platform desktop email client that you throw around as a model to follow. Even your current Inbox by google is a phone only / web only application and not a cross platform desktop email client. Claws[1], sylpheed[2] are such cross platform desktop email client competing with thunderbird and I don't any of the features you're complaining about I do not know what you are referring to when you mention thunderbird has awful spam protection. I maintain a dozen of TB installs and they do a great job of filtering spams for those who do not know better email hygiene. You should try experiencing email outside of the giant mega centralized repository that is killing the web and internet and see how it's done in the outside world that you seem to not visit often.
