The terms presort and commingle are often used interchangeably in the world of mail … sometimes even by mail professionals themselves. But there is a difference, which is helpful to understand when you are seeking the lowest postage rates for your business or organization.
In a nutshell, presorting mail is grouping mail by zip code for a single customer.
The definition of commingle is to blend. Your mail is mixed, or commingled, with mail from other organizations in order to achieve USPS discounts. Doing a presort mailing will save you money; but commingling your mail might save you more.
