Gmail regularly lets through spam, including backscatter spam from mail sent to the google.com domain spoofing Gmail users. Industry-leading is not the term I would use to describe their spam heuristics.
Grey listing has been far more effective at stopping spam than some half-baked AI garbage from Google.
I forward everything including spam to Fastmail. Their spam filter is absolutely fine. This way I don't need to check for false positives in 2 places. You're probably losing one genuine message a year if you don't check your Gmail spam folder.
Hmm. Not really. I run greylisting on my personal domain which is extremely low traffic and lately I'm getting like 4-5 spams per day that obey it correctly.
Which is more than the non spam emails that come on it :)
I control spam by using email aliases. And it makes it easy to track exactly who leaked/sold my email address. But I don't use gmail, as I value my privacy.
I whitelist using regular expressions (specific prefixes mostly). Gibberish and random localparts are unlikely to match those, it effectively never happens.
Agreed, there are also ways to employ aliases which won't prevent spam, but this still doesn't explain the relation to the subaddressing regex or why other ways or employing aliases (e.g. masking) are never enough.
Just joking, I expect nothing from GMail team after I noticed that "block sender" option just puts emails in spam folder instead of deleting them on arrival.
Proton Mail is good (just not as good), but you can't integrate external SMTP for outbound emails; you have to pay to send from @yourdomain.com.
With Gmail, you can configure an external SMTP server using "Send mail as" setting. Super convenient. Tons of mail services offer a generous free tier for personal use (e.g., Mailgun 100 emails/day).
It's not really worth paying just to send a few personal emails from @yourdomain.com each month.
