Tri-Fold Mailer with Tipped, Stepped Booklet

Here’s a great found sample from Delta Airlines and American Express. The oversized self-mailer starts with a die-cut short panel on the cover that opens to reveal a Tri-Fold format that works as a carrier for an 10-page (yes, 10-page!) tipped-on waterfall booklet. The booklet holds customized content and special offers in an organized, stepped format. This concept could be used for many different verticals, too. Great mail!
