My email was connected to my iphone, I deleted it to move to a new phone, it now says that the email does not exist

I deleted everything off of my iPhone 4 to move to an iPhone 5, and once attempting to log into my email address on my new phone it says that my email does not exist. Everything is linked to this email and I urgently need to be able to access this email address, is there anyway to sort this problem out without starting from the beginning and creating a new email address and cancelling everything?
