spam filtering
Email trash sorting
Spam filtering is the process of automatically detecting and separating unwanted messages—typically email—from legitimate ones.
Filters use various techniques: scanning for suspicious keywords, checking sender reputation, or analyzing patterns common to bulk messages.
Most email services apply spam filtering automatically, routing suspected junk to a separate folder: Check your spam filter if you're missing emails.
