How to permanatly block what's app from my e-mail?

This is some type of Iphone, blackberry etc. App. I do not want. I can't delete them and There's no remove me or unsubscribe. I find them very annoying and wish they would leave me alone.

Just mark it as a spam mail. It won't bother you again

Alex is right, mark it as spam and that should solve the problem. But if it's legitimately from What's App then there should be an "unsubscribe" link at the footer (bottom) of the email.

Agree with Alex and Justin. There should be a link to unsubscribe the mail in the footer of mail just click on that link.
