Email filtering
How incoming mail is sorted into the inbox, spam or other folders.

In practice
Providers combine authentication results, sender reputation, content and recipient behaviour. Users add their own rules on top. No single factor decides placement.
Verification and sending
Filtering happens after a message is accepted, so a valid address can still send you to spam. Verification only addresses the part before that.
