Direct mail marketing glossary

Stay current with the latest direct mail marketing terms.


Self-mailers are simply mailpieces that arrive outside of an envelope. A postcard, a catalog, a booklet, or a sealed piece of paper could all be considered self-mailers in their own right. For marketers, self-mailers provide a minimalist template for reaching customers and increasing ROI with little planning and effort. They're inexpensive, easy to create, and likely to grab your customer's attention when they open their mailbox.
