Nothing but Love received two and a half stars out of five from AllMusic, which called it "a terrific debut which banishes any concern that the Wilkinsons are simply a novelty act." The review stated that "The trio's vocals blend perfectly and Amanda, who sings most of the leads, has an outstanding voice." Rick Teverbaugh of Country Standard Time gave the album a favourable review, writing that "the end result is more pleasing than hokey, more honest than fabrication and more touching than cutesy." He added that "Steve Wilkinson is the writer and hits the mark more often than not" and "Amanda is clear-voiced and aided by the fact that she doesn't try too hard either to convince anyone she has lived through these songs or that she is capable of sounding older than her years."
Matt Bjorke of about.com gave the album four stars out of five, stating that "The Wilkinsons were instantly noted for their crystal clear harmonic vocals" and "if you like a group that sounds exquisite together, then you should check out The Wilkinsons' debut album."People picked the album as their Album of the Week for September 28, 1998, saying that The Wilkinsons "generate tight harmonies without sacrificing a lively sense of rhythm." Their review went on to say "all three Wilkinsons get to shine with lead vocals at some point here" and "good taste keeps the music unsullied and fun."
