The Mailing Label / Mail Merge utility is an extremely powerful utility program in its own right but has evolved into something far greater than it's original purpose.  Yes, it can print mailing labels or even direct marketing pieces.  Yes, it has its own abilities to gather the data for these mailing, but it can also import the data from the Periodic Hot Seller or from the power spreadsheets.    It then can take that information and export it out to Constant Contact or to Microsoft Excel.
