Spam filters rely on many signals besides the from address to decide if a message is spam, because one signal alone is often not reliable enough.

It’s hard to see who deals with spam with the best because when the filters are working well, you don’t notice how much is being blocked.

I can say that both Fastmail and Google work fairly well. Unless things have changed, about 90% of email is spam, with most getting blocked or diverted at different levels. So even if some gets through, it’s possible the systems to block it are still working very well.

Subscribe to things with personalized individual aliases instead of your main address.

That way you don't get much spam to begin with because they'd have to guess what aliases you use, and you reject anything that's not sent to one of those aliases.

Assuming one of the sites you subscribe to sold you out or was broken into and their alias starts receiving spam, you simply block or disconnect their alias.

If you haven't been doing this, the address you use now (for everything) is undoubtedly on many spamming lists. It's best to get a domain and start moving subscriptions to aliases on that domain.

Nobody should ever know the main account address, it should be reserved for logging in to the account. Even friends and family should be given aliases (because their address books and contact lists inevitably get sold and compromised eventually).

I just use a separate email for subscriptions and whatnot vs "actual" email. That helps mitigate a lot of it since I can easily dismiss any "business" communications from one and be on my guard with the other.

But the real solution imo is to not use email for such things. If I need to renew something yearly, I set up a reminder on my calendar or wherever yearly.
