[7] Poppy Reid from Rolling Stone Australia gave the album a perfect score, saying, "Amy Shark has always been led by vulnerability, but what places Sunday Sadness in the lead of her long-player canon is that it feels more seductive than its predecessors.

"[8] John O'Brien from The Courier-Mail described the album as "i.a grab-bag of musical styles, from the retro electro-rock of 'Can I Shower at Yours' to the breezy guitars of 'Loving Me Lover' and the Lisa Loeb vibe of autobiographical 'I'm Sorry'.

"[9] Zoë Radas from Stack Magazine described the album as "a collection of gems that are as easy to binge as a pack of peanut M&Ms" and closes the review saying "Sunday Sadness thumps all the bells it sets up.

The combination of brilliant guitar riffs, innovative production, and unforgettable lyrics showcases Shark's confidence and mastery of pop music.

"[11] Mike DeWald from Riff Magazine said "As a complete work, Sunday Sadness may be Shark's most cohesive record from front to back, with a balanced mix of the familiar and unfamiliar all fitting under the same umbrella.
