Gmail is rolling out a new link called “Delete all spam messages now” so you don’t have to repeatedly select all messages and delete them. Another new feature: “Empty trash”.
When Google first came out with GMail they touted their large email storage, as a reason why a typical user will never have to delete email. Today on their blog , they announced a new feature to easily delete spam and trash, by easily selecting all their emails. I guess, people do really need “delete” their email.
