Braintree Labs Web Key Mailer: Promotes Free Samples

Braintree Labs used this direct mail campaign to promote free samples of its bowel prep medication, Subprep, to prospective patients. The inside of the mailer carried a dimensional piece with a web key that swung out from inside using a "jackknife" type of motion. The web key launched a site where patients could request free product samples and personalized prescription pads.
