"Mon amour" was a commercial success, peaking at number one in Luxembourg and Greece and within the top five in France, Belgium and Switzerland.

Slimane entered the Eurovision Song Contest as a way of means to share his work, his music, and to represent France.

[4] The song itself has been described as an "ode to romance and love... with a poetic yet strong melody" by ESCUnited writer Arnaud Abadie.

[7] The song officially premiered on France 2 television show Journal de 20 heures later that day, with Slimane performing a live version.

[9] He first gave a live performance of "'Mon amour" during a France Télévisions New Year's Eve special programme on 31 December 2023.

[20] Vulture's Jon O'Brien ranked the song 26th overall, describing it as a "chanson so quintessentially French it might as well be performed by a beret-wearing bicyclist holding a baguette".

[23] National Public Radio's (NPR) Glen Weldon included it in his list of 10 overall favourites to win the contest, deeming the song to be a "straight-down-the-middle ballad with a searching, plaintive, torch-song quality that's more quintessentially French than a beret slathered with Camembert and stuffed in a baguette".

[27] For its Eurovision performance, the song was altered so that Slimane could sing a verse a cappella; a suggestion that was made by collaborator Zach Reece.

[31] During a dress rehearsal before the grand final, Slimane stopped his performance during the song's last verse, declaring a message of peace and unity; a message that was interpreted by NME as an alleged response to Israel's participation in the contest along with the disqualification of Dutch contestant Joost Klein.
