Sometimes sending someone an email when you are blocked it will go through without sending an message but instead of going to that person's inbox it will go to "filter" an automatically be deleted.
EDIT: No they cannot read the email because they have your email blocked therefore it may not go through at all and you will receive a message saying it failed to deliver or it will go through but instead of the person getting it and reading it they have it filtered so it would automatically be deleted either way.
