deleting and blocking

New Email
is there an easy way to delete emails without having to click on each one ? I tried to "select all' and it wouldn't; Can specific email senders be blocked? I sometimes have 200 plus messages a day. Then after I delete them they are still in 'deleted messages' and have to be deleted again. Does having all these emails affect my computer or can I just ignore them?
