Question about Outlook Express

I would like to send out personalized emails (i.e,, include their first name in the salutation, City name in the body of the email, etc) using my Outlook, but am unable to find a way to mail merge.  Does anyone know a way that this is possible?  I have to send about 50 emails at a time out fairly often, and need them to be personally addressed to each recipient.  There has to be a better way than creating 50 individual emails with essentially the same information, just with personalized tweaks.
