Inbox

Many providers sort the inbox into tabs or priority sections. Mail that fails filtering goes to spam or a promotions tab rather than the main view, so “delivered” does not always mean seen.

A valid address can still send your mail to a tab or to spam. Verification only covers the part before that.
