In later years, the track found more success and entered the record charts in several countries other than the United States. According to Springer, the retrospective success of "Santa Baby" was completely unexpected. In an interview with the "Los Angeles Times", he said: "I ask myself, ‘How come?' I've written so many songs that, to me, musically are much better than 'Santa Baby', and they're not popular. The answer has to be that 'Santa Baby' has a magic that goes beyond a composer's plans." In Canada, the single reached number 43 on the Digital Song Sales chart in 2007 and peaked at number 42 in 2008. In the United Kingdom, Kitt's version of "Santa Baby" debuted on the UK Singles Chart in 2007, when it hit number 85. It had previously reached number 30 on the accompanying UK Singles Downloads Chart in 2006. The single had its best performing period during the last week of 2019 when it re-entered the main chart at number 55, its highest peak to date. The British Phonographic Industry later awarded "Santa Baby" a gold certification, signifying certified units of 400,000 copies. In France, the single debuted with a peak of number 92 on December 28, 2013; it dropped to 113 the following week but rose to 96 the week after that, marking its last appearance overall. "Santa Baby" also charted in Germany and Switzerland and positions 73 in 2018 and 94 in 2019, respectively.
