Don't click on the link in Marcy's email titled "hello" as it's one of the hacked spam emails that will then go into your email acct and send spam to all of your contacts. Just delete her email and you won't have any problems.
We've had this happen from time to time. When you receive a strange email like this that usually doesn't have an explanation, often isn't titled or just titled "hello" or "hi" just delete and your email will be safe. Otherwise all your friends and family will start getting the same stuff sent to them!!!
