The benefit of this mailer is that sometimes with a dissolve mailer the image doesn’t work being split over various panels, with the window revealer direct mail piece this isn’t an issue. This simple, yet effective design is great for communicating a message in two phases or before and after messages. The interactive aspect of this mailer delivers your message in a memorable way, increasing sharing and response rates.
