To support the album, Vera Blue embarked on the Mercurial Tour, commencing in the Gold Coast on 3 November 2022.

[9] Bryget Chrisfield from Beat Magazine said "Mercurial intersperses soul-searching ballads with electropop bangers for dancing the hurt away."

Chrisfiend ended the review saying, "her vocals are perennially flawless and, throughout the deeply personal Mercurial, Pavey embraces vulnerability as a superpower.

"[10] Zoë Radas form Stack Magazine said "Mercurial has been crafted with the stage in mind; it's changeable and volatile like its namesake, full of thick bass and synths, and imbued with an urgent spirit.
