Do yourself a favor and don't get this program for mailing. It is SLOW and an absolute waste of time if you are doing multiple mailers every day. The programs does not function as they say it should, I wasted $1500.00 to find this out and they won't refund my money. It must be written by third graders, they can't seem to get their dictionary to function at all, so address correction takes forever. Just to print out the reports takes 3 minutes!!
