How do I disable all the spammy e-mails I get

I recieve messages from Launchpad overly often. I do not want any e-mails from Launchpad, my spam filter gets most of them but not all of them, and I can't make a rule to send all e-mails from this sender to this folder because the sender always depends on the question! I wanted to but all legitament e-mails from launch pad in a certain folder for reference but I can deal with not receiving any emails from launch pad.
