after being checked for final fixes your mailing list is ready to
be mail sorted for the USPS® and provided with IM Barcodes, Sort
Position, proper paperwork, files and postage amount. This is
the final step in processing a data file for mailing.
These steps are necessary to provide our clients with discounted
postage due to the number of ZIP+4 verified addresses, saturation
and automation rates. To put it simply, the cleaner the data,
the better the result.
