spam filters
Junk mail blockers
Spam filters are software tools that automatically detect and divert unwanted email—advertisements, scams, phishing attempts—away from a user's inbox.
They analyze message content, sender reputation, and other signals to sort legitimate mail from junk.
Check your spam filter if you're missing expected emails.
The term extends to similar screening on social media and messaging platforms.
