Desiree O from
Brit + Co website gave the song a positive review, saying that "with shades of the signature Jackson sound, a totally fun beat and a chilled-out breakdown mid-song, this could very well be your fave jam of the summer. When you hear Janet’s final "dammn" at the end, you’ll be hooked!". Saeed Saeed from
The National deemed it "irresistibly funky with its super-fat bass lines". Alex Macpherson from
The Guardian simply said "The chunky bass of Dammn Baby hits the dancefloor spot". Rob Tannenbaum from
Billboard magazine noted that "Dammn Baby" and another song on the album, "2 B Loved", were "pretty explicit nods to DJ Mustard's "ratchet" sound".
PopMatters' Evan Sawdey shared a similar sentiment, saying "the excellent and not-misspelled" song "betters DJ Mustard as his own low-end synth game", although he noted that the song's breakdown was "pure Janet".
Michael Arceneaux of
Complex opined that he was more partial to songs like "Dammn Baby", "Dream Maker/Euphoria", "No Sleeep" and "Night". In a more balanced review,
AllMusic's Andy Kellman noted that the song's "probing synthesizers, booming bass, and relatively detached vocal" came across as "conscious concessions to commercial radio". In a separate review, Emannuel Elone from PopMatters website was critical of "I Get Lonely"'s interpolation, saying the idea was "cute", but not enough to "lift this song up quality-wise to where it should be". ==Chart performance==
