The album's artwork was provided by Sandy Brummels, while Robert Sims handled design, and Jonathan Mannion was responsible for photography.

Several artists made an appearance on the album, including Justin Timberlake, Kelly Rowland, Beanie Sigel, Freeway and Dani Stevenson.

[8] Wayne Franklin of PopMatters held low expectations for the album prior to listening to it, following Nelly's feud with rapper KRS-One, but found its music to be "incredible".

[18] Wayne lauded the track "Air Force Ones", describing it as an "unbelievable ode" to hip hop, while noting several other songs as stand-outs.

[18] Allmusic's Jason Birchmeier gave the album three-and-a-half stars out of five, noting "Hot in Herre", "Dilemma" and "Roc the Mic" as "three well-calculated, standout moments".

[9] Birchmeier praised "Hot in Herre"'s production, "Roc the Mic"'s hip hop composition and the "Dilemma"'s interpolation of Patti LaBelle's "Love, Need and Want You".

[9] RapReviews.com's Steve Juon gave Nellyville an 8.5 out of ten, citing the album's consistency and production, praising "Hot in Herre" for its Midwestern drawl and "harmonious musical flow".

[21] Rabin criticized Timberlake's "high-schooler doing a Bee Gees impersonation" on "Work It", though noted the song as the only "glaring misstep" on the album.

[20] People lauded "Hot in Herre" for its "funky go-go groove", declaring it the "perfect summer jam", but were ambivalent towards the rest of the album's beats for being slightly repetitive.

[22] Rolling Stone's Rob Marriott described Nelly as a "gifted, witty MC" with the "catchiest rhymes to ever hit the pop charts" but wrote that Nellyville sounds "weighted down" by the commercial pressure of having to have another multi-platinum album.

[23] Nelly received three BET Award nominations such as Best Male Hip-Hop Artist, Best Collaboration (for "Dilemma") and Video of the Year (for "Hot in Herre").

[36] The former track was number one on the Hot 100 prior to the album's release, maintaining a third week atop the chart, when Nellville made its debut.

[44] The album dropped off the chart after 31 weeks, and was certified Triple Platinum by the Australian Recording Industry Association (ARIA) for shipments of 210,000 copies.

[51] Nellyville also achieved success in several other territories, peaking within the top ten in Ireland,[52] Netherlands,[53] Denmark,[54] Finland,[55] Switzerland,[56] Norway,[57] Austria and Belgian (Flanders).
