Have got married so changed email address. Both with Hotmail. How can I get my old contacts into my new email a/c

I now have two email accounts with Hotmail. One uses my maiden name and the new one is in my married name. Is there an easy way to copy my contact list into my new account, or do I have to write to everyone telling them my new address. If I do this, it will be easier from my old account, where the contacts are located, but harder for them to save my new address. Any suggestions?
