It's just more work to maintain 2 mailing lists. Lifesaver can do it all. Just give them different codes. It is so easy to sort lists in Lifesaver. For example, on all regular customers you put an M in the catagory field when you enter their address, onn those you hope to never hear from again, put an X, on the commercial/business accts. put B. You can put whatever you want in it, F for family, P or personal friends, S for suppliers and on and on. You can print as many catagories as you need, or only one. You can sort them by name, zip, catagory, street, whatever, it's very easy. Sorting by zip is great if you use bulk mail. The list can be exported to another program, say for personalizing mailings "Dear Mr. XXX"etc. For sorting and printing labels and lists, LIfesaver is great.
