Notes

About

This is an independent guide to direct mail as a channel: what it is, how it's built, what it costs and how to choose between the ways of sending it.

Our rules

  • Prices and mail rules come from USPS: the price list (Notice 123) and the Domestic Mail Manual. Every page links its sources and shows when it was checked.
  • No made-up statistics. Plenty of sites quote response rates without a source. We don't publish a number we can't trace.
  • Drawings, not stock photos. The examples are ours, with invented businesses.
  • No sales. We don't print, mail or sell lists, and there are no affiliate links.
