Spam filter what is it

Spam filters can help you by preventing unwanted emails from entering your inbox. While this may sound like a straightforward task, it can be a challenge for filters that are not constantly updated according to the most recent spam techniques and senders.

Spammers may change the address from which emails come or the wording inside the header or body to bypass out-of-date spam filters.
