Create A Distribution List For Outlook

I want to email with excel, and I know how to do it if I have a distribution list already set up in outlook. I want to avoid having this DL in outlook though, and instead keep a list in the actual excel workbook. I tried having the list and then combining all the cells with a semicolon inbetween the addresses into one single cell, then assigning that cell to a variable and inserting it in the cose in place of the DL name, but it doesn't work. Apparently you can't mail to mutliple address thru the VB code, either a single address or a DL. Am I incorrect in this? So I thought maybe I could somehow create the DL first using the names in the list thru code, and then using that DL name to send the workbook.
