Nielsen Study Proves the Impact and Attraction of the Printed Envelope

Printed envelopes were opened and their contents read by 84.5 percent of recipients, which made them the most opened advertising (vs. standard envelopes—75.6 percent, self-mailer—71.4 percent and wrapper—71.2 percent). While all postal mailing versions lead to readers informing themselves more about the product to a similar extent, the printed envelope outshone the competition in one specific way: no other mailing version was valued as highly.
