How do I enter multiple contacts all at once, simultaneously, from an xcel list sheet?

How do I enter multiple contacts all at once, simultaneously, from an xcel list sheet? I do not want to enter a contact one by one. I am sending out an ad and wish to send it straight from my list of contacts, yet i have so many to enter into my hotmail contacts list. also, can a copy of a draft be saved as a multiple draft for the same copry per amount needed of the same exact draft? thanks.
