How did I manage to get someone else's email address beside my email address ?

Up at the top of the page where it states who sent the email, it has someone else's email (yes I know who she is) along with mine.


How did this happen? How can I fix this?

Reply:this means that the person who sent it also sent it to that other e-mail too.
Reply:A simple misspelling of the email address will do this (even if it looks the same I am betting there is something unique about the address- check it very carefully).





Just make sure that the address is 100% right.
