Merlin Readability Rate Rises July 31
Merlin, or Mail Evaluation Readability and Lookup Instrument, checks address accuracy for mailers receiving automation rates.
More than 94 percent of flat mailings are passing at the current quality threshold, according to the USPS.
Mailers that don't meet the new threshold but achieve the former standard of 80 percent will continue to receive some discount.
