2.x add ability to prevent sending notifications with users that did not have email verified

[luceos]

This is a tentative PR to see if this is something we want.

reason

We are sending emails to user that never verified their email address. In addition we could use this property on the Users table to disable sending in the case that a) delivery fails (bounces) or b) users mark the mail as spam. In both these cases we no longer want to send email because that negatively affects our email sending reputation.

This is not just a global thing.

solution

Offer a blueprint method to signify whether the blueprint can ignore the verification of the user.

next

If we do this, I can update the blueprint implementations to match.
