marketing our customers

hi all,

we would like to send out a electronic invitation to our customers @ an upcoming show.  I was wondering if anyone had any idea how I can import the email addressed from an excel file and populate the 'to' field to send out the invitation.  as for the from field, I guess a static address like our company info email.

as for the contents of the email, would this be done via a temp in outlook or can all this be done via word.

thanks in advance.
