Unwanted emails come from either a known contact or unknown contact (maybe ads). The Google spam filter which comes with every Gmail account categorizes the messages that come to your box. Mine, for example, is categorized into three; primary, social and promotions. There’s also a Gmail spam folder where Google’s proprietary Gmail spam blocker automatically moves messages it detects as spam. This is done to ensure you get only the relevant messages in your primary box. However, the categorizing is done by a machine and of course, you can’t truly expect 100% accuracy.
