In this episode of The Copywriting Podcast, Lucas and Luna explore the power of specificity in direct mail copy.

Lucas explains the psychology behind concrete language, citing research on how specific adjectives trigger stronger sensory recall. Luna shares a modern parallel from email subject lines. The episode offers a practical framework for choosing words that land, plus a warning about the risk of being too specific.
