Empty Lighthouse Magazine called the album Kelly's "break into the industry" with applaud to her songwriting and vocals.^[21] Music Snake wrote that the album was an "impressive debut" with Kelly being "boldly authentic and effortlessly talented."^[22] In a review from Trendio, the album was called "timeless" and lived up to expectations. However, it was said that Kelly should have broken out of her comfort zone a little more.^[23] Matthew Scott Donnelly from PopCrush rated the album 3 out of 5. He wrote that the first half of the album surpassed the second half and closed with "Kelly’s got pipes that could stop an Olympic sprinter in her tracks—and she’s got a great album in her—but Unbreakable Smile, for its undeniable glint, could do with a bit of elective orthodontia."^[24] AndPop's Merna Jibrail complimented the album's variety although she noted the lack of singles that could have potentially built more momentum and promotion for the album.^[25]

The album was predicted to sell 65,000 units in its first week and debut in the top five of the US Billboard 200.^[26][27] The album debuted at number two on the Billboard 200, with 75,000 album-equivalent units, including 65,000 pure album sales.^[28]
