Box Letters Revealed: Secrets Only Email Enthusiasts Know! In the fast-paced world of digital communication, where subject lines and formatting dictate open rates and engagement, mastering subtle but powerful design cues can give your emails a competitive edge. One underrated trick that email enthusiasts swear by is the strategic use of Box Letters—a visually engaging, structured formatting technique that enhances readability, draws attention, and organizes content with clarity. ### What Are Box Letters?
