Jeremy Reed writes in his biography of Almond, The Last Star, that Untitled was "cheap and starkly recorded". He states that Almond received "little support from Phonogram for the Mambas project, the corporate viewing it as non-commercial and a disquieting pointer to the inevitable split that would occur within Soft Cell". An article in Mojo noted that "from the beginning, Almond and Ball had nurtured sideline projects, though only the former's – the 1982 double 12-inch set Untitled – attracted much attention, most of it disapproving." The article mentions that Almond "who preferred to nail a song in one or two takes" stated that it was all "about feel and spontaneity, otherwise it gets too contrived" when accused of singing flat.
Neil Tennant, then a journalist at Smash Hits, reviewed the album saying that the band "have obviously enjoyed producing some intriguing, if self-indulgent, new music and their own versions of some old favourites".Stephen Thomas Erlewine of AllMusic also calls the album "intriguing" but states that Untitled "doesn't ever add up to anything cohesive", whilst acknowledging that Almond has "made a conscious departure from Soft Cell".
