The album has received critical acclaim. D.M. Edwards of PopMatters stated: "The arrangements by Arthur Greenslade are excellent and there are plenty of glimpses of the experimentation which would be a feature of Gainsbourg's music," further describing the album as "sophisticated, timeless pop music."[5]
In 2017, Pitchfork placed it at number 44 on the "200 Best Albums of the 1960s" list.[6] Writing for Pitchfork, Cameron Cook called it "a love letter read out loud by its recipient: Every note and lyric is meant to highlight a certain aspect of Birkin's persona though Gainsbourg's lens, from her breathless delivery of every line to her heavily accented, coquettish French."[6]
