"Hello Heartbreak" received universally positive reception from critics. Mikael Wood of the Billboard described the song as a "shiny electro-R&B gem",[1] while Josette Compton of Entertainment Weekly noted the "technodriven" track is "reminiscent of Kylie Minogue".[2] Pete Lewis of Blues & Soul also compared the song to other works, commenting that the "synth-heavy uptempo cut" "heavily" relies "on the kind of Euro-dance-inspired electronica utilised recently by fellow US urbanites like Timbaland and Justin Timberlake".[3]
