Spammers are starting to use email addresses with "renewal" in the address, bypassing junk filters. How do we fight this without blocking legitimate renewal emails? (lemmy.world)

For several months now I've started to receive an unprecedented number of emails from addresses named some variation of "renewal@".

The issue is that creating an email filter which would move these emails to your junk folder would also inadvertently move legitimate subscription renewal emails to your junk folder as well. What are some steps that can be taken to deal with this issue? Which apps, clients, or email services deal with junk/spam the best?

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.

Yeah and I have to be honest, usually outlook/Hotmail is pretty good about adapting to spam but this seems to have evaded them for much longer than other types of spam. Fingers crossed they figure it out soon
