The Ink Spots recording became the 10th best selling single of all time with over 19 million copies sold making it one of the fewer than forty all-time singles to have sold 10 million (or more) physical copies worldwide. According to Lawrence, he mailed the song before showing it to some of his friends. His friends' reaction to the song was almost unanimously negative, but he remained positive on it and later it became one of his biggest successes. It was added to the Grammy Hall of Fame and was number 271 on the "Songs of the Century" list. In 2018, the Ink Spots' recording of the song was selected for preservation in the National Recording Registry by the Library of Congress as being "culturally, historically, or artistically significant."
