Wunna received generally favorable reviews from critics and debuted atop the US Billboard 200, earning 111,000 album-equivalent units of which 4,000 were pure sales, becoming Gunna's first number-one album.

[19] Reviewing the album for HipHopDX, Mimi Kenny stated "Gunna received invaluable support on his way to fame, but with Wunna, it looks like he may be able to take it from here".

[18] Danny Schwartz of Rolling Stone praised the album, stating, "While some of his writing is of the Fisher-Price variety—one verse in "Met Gala" employs a AAAAAAAAAAAAAAA rhyme scheme—and his lyrics aren't always well thought out ("Say the wrong word, and I'mma shoot him in his shit"), Wunna remains a transportive listening experience, due in large part to its production, which exists in almost perfect harmony with Gunna's soothing vocals".

[21] In a mixed review, AllMusic critic David Crone wrote the following: "While WUNNA deserves points for its cohesiveness and impressive highs, its padding proves its downfall: the album's closing run means it remains a pick-and-mix affair, rather than a definitive statement.

"[16] In a negative review, Beats Per Minute's Chase McMullen stated: "Should you desire to be kind, you can call the album mood music.
