Deliverability
How reliably your email reaches recipients’ inboxes rather than bouncing or landing in spam.

In practice
It depends on authentication, sender reputation, content and list quality. Delivered means the server accepted the message; deliverability asks where it went afterwards.
Verification and sending
List quality is the part verification changes: fewer invalid addresses means fewer bounces and a cleaner reputation. It is not by itself a promise of inbox placement.
