Grande promoted the song with televised performances at the 2016 Billboard Music Awards, the season 10 finale of The Voice, and the 2016 Summertime Ball.

[2] Musically, "Into You" is a dance-pop,[3] house,[4][5] electro[6] and EDM[7][8][9] song featuring "a thudding club beat, lurking synths and sharp clicks".

[11] "Into You" starts with "a minimal club beat", before "crescendoing into [a] thumping chorus",[12] where "an uptempo disco backline explodes into a monstrous club-ready hook", as noted by Complex's Jessie Morris.

[3] Lyrically, the song has Grande singing of "waiting for her love interest to stop the conversation and finally make a move".

[15] Digital Spy editor Lewis Corner noted the possible references to Elvis Presley's "A Little Less Conversation" (1968) and Mariah Carey's "Touch My Body" (2008) that are made in the chorus, where both phrases appear together.

Jamieson Cox of The Verge stated that the track "might be the catchiest song cut from the album to date", adding: "You can thank — or blame — pop god Max Martin and his cabal of songwriters for those razor-sharp disco synths.

[14] Writing for Rolling Stone, Sarah Grant said the song "is primed for dance floor makeout sessions" and that "Grande swaggers with little affect in tight vocal range".

[22] NME's Larry Bartleet called "Into You" a "[c]lub anthem-to-be",[23] while Sal Cinquemani from Slant Magazine named it a standout on Dangerous Woman.

[24] MTV News' Sasha Geffen observed that the track "brings more heat than anything we've heard from Dangerous Woman so far, proving [Grande] hasn't lost her touch for electric dance floor jams".

[25] Writing for Billboard, Lisa Brown praised the "infectious distorted beats", declaring that "she still stays true to her sensual 'dangerous woman' inspiration".

[15] Hayden Wright from Radio.com analyzed that the song "combines pulsating electro beats with Grande's iridescent vocals, a tried-and-true recipe for her biggest hits".

[27] Theon Weber of Spin complimented the song's chorus and lyrical content of its verses, declaring that it "redeems the floor-filling thud with a demand for 'a little less conversation and a little more touch my body'".

[28] Billboard ranked "Into You" at number six on their 100 Best Pop Songs of 2016 list: "Dangerous Woman is rife with provocative lyrics, but the album's second single feels like the sexiest track of them all", due to its "seductive" bass and Grande's "alluring vocals.

[41] As of June 2020, the song has sold 792,000 copies in the United States, where it has been certified quadruple platinum by the Recording Industry Association of America (RIAA).

[47] The song also peaked within the top 20 in Argentina,[48] Belgium,[49] Canada,[50] the Czech Republic,[51] Greece,[52] Guatemala,[53] Hungary,[54] Iceland,[55] Ireland,[56] Latvia,[57] the Netherlands,[58] Scotland,[59] and Slovakia.

[69] The performance included backup dancers and pink smoke, and was listed as one of the best of the night by editors from Billboard, Rolling Stone, and Time.

[77] Grande released a remix of the song by Alex Ghenea that features American rapper Mac Miller on August 6, 2016, exclusively on SoundCloud but later made it available for digital download.
