It received generally mixed reviews from most of the critics, with some complimenting its production and Mars' vocals on the song.

It also peaked within the top ten of the charts in Australia and the top twenty of the charts in the United Kingdom.
In an interview with American Songwriter Philip Lawrance he explained the concept behind the song "When we were coming up with that song, we had this image of a slow-mo video in Vegas of a couple running, and she’s in her gown and he’s in his tux, the wedding party is behind them and everyone’s raging. This sort of crazy, daring, wedding feeling. It was more of a racy kind of idea, as opposed to this classic marriage tune it has become." He added "We always thought it was a good song and catchy, but we didn’t think it would affect pop culture the way that it has. The first time we saw one of those YouTube videos, it changed everything for us. We were almost in tears, just the power of music… the power of what it is we can create. These ideas, words, and lyrics and how they can get into the fabric of society and affect people’s lives in such an amazing way."
"Marry You" received mixed to positive reviews from critics. Tim Sendra of Allmusic said the song was "pleasantly silly", but praised its "dynamic and nuanced production". Mike Diver of BBC Music simply called it a "too-clingy and very creepy love song". Ken Capobianco of The Boston Globe called it an "artfully arranged throwback" love song, and said Mars' "plaintive voice aches oh so gently on [it]". Leah Greenblatt of Entertainment Weekly wrote that "a malt-shop heart beats beneath the digital skin of tracks like the buoyant "Marry You". Eric Henderson of Slant Magazine thought the word "fuck" got replaced by "marry", referring to Cee Lo Green's hit, "Fuck You". Becky Bain of Idolator was impressed with the song and described it as a "Motown marriage track". Joanne Dorken of MTV UK called it "the infectious album track", and said it was a "reminiscent of something Jack Johnson would have recorded". Editors from USA Today wrote "though [Bruno Mars] despairs about a woman who doesn't share his affection on the melancholy "Grenade", he's more than ready to give into his capricious impulses on the bubbly "Marry You".
