music style, described as "slink, slow-jam R&B sounds." The song is set in signature common time and written in the key of G minor. It features a basic chord progression of Gm-Cm-D7-Gm. Carey's vocal range in the song spans from the low note of B2 to the high note of F5, with the piano and guitar pieces range from G3 to G5. The track was very different than anything Carey had ever recorded, incorporating strong "Latin cultured background." The instrumentation and vocal arrangement used in the song was compared to Kenneth "Babyface" Edmonds' productions, due to its "soft R&B coos and guitar melodies." Critical reception "My All" received acclaim from music critics. Stephen Thomas Erlewine from AllMusic chose the song as one of the three "track choices" from the album. Daryl Easlea for BBC said it "encapsulates her more traditional, straight ballad approach with Latin overtones." Larry Flick from Billboard praised the song, calling it an "anthemic gem." He also described the song as "sparkling with a house flavor that's mildly reminiscent of Toni Braxton's landmark 'Un-break My Heart'."

It's 10 minutes of pure disco bliss." David Browne from Entertainment Weekly praised the song's instrumentation, noting "with its gently plucked guitars, is the best Babyface track Babyface never produced." Another editor, Mark Bautz, felt it stand up as one of "the best pop tunes of the '90s."

Virginian Pilot described the song as a "lush pop ballad" that has been "tailor-made" for Carey. Chart performance Although "My All" was the fifth single released from Butterfly, it was only the second commercial worldwide release.
