I have a list in Excel of 10,000 addresses that I've copied from the town's census list. I want to do a large mailing, but do not know how to do this? Right now, the addresses are set up in columns in Excel:

A - Last Name
B - First Name
C - Middle Initial
D - Street Number
E - Street Name
F - City
G - State
H - Zip

What is the best way for me to utilize this infomation to send out a mass mailing to the town introducing a new business in the area?

Thanks, Pep
