Open Letter is the third studio album by American R&B singer Case. Released in 2001, the album continues his smooth, mid-tempo R&B style, focusing heavily on love, heartbreak, commitment, and emotional reflectionframed as if Case is speaking directly to a partner through a personal letter. Musically, Open Letter blends contemporary R&B, soul, and soft hip-hop influences, with polished production typical of early-2000s R&B.
