There isn’t anything really. I drank the koolaid and I lived in my mail for decades. My inbox has 100000s emails and my life is there. Alternatives I tried, for instance outlook, fastmail and others simply die when I turn the hose there. And that’s just new email, not import which I need too, of course. Gmail doesn’t flinch and is always fast.

Just be prepared for it all to go away when you need it the most. Thunderbird can import your past mail

I run google exports and that makes a massive mbox file; thunderbird cannot import it. It hangs and then crashes.

Use pop and download/delete each message at a time.
