Following the preview-trailer launches, Chopra promoted the film by appearing with seven men (dressed as bridegrooms) at the Radio Mirchi FM studio. The succession of marriages and funerals was illustrated at a promotional event for the film, where Chopra appeared as a Catholic bride in a wedding gown holding a bouquet. A short time later she reappeared as a widow in mourning, for her husbands' funerals. Emphasizing the film's theme, Chopra introduced a "seven ways to lose your Valentine" press kit for reporters at a Valentines Day promotion. The kit contained a rope, a syringe, a knife, a bottle of poison, a sachet of potassium cyanide, an ice pick and a blister pack of Viagra, which was based on Susanna's way to kill her husbands in the film. In February 2011, a book entitled "Susanna's Seven Husbands" was released by Penguin Books as a collector's edition including the novella, the short story and the film's screenplay. The film was screened at the 61st Berlin International Film Festival as part of its world premiere in the festival's Panorama section. At the Friedrichstadt Palace (a Berlin theatre) an audience of some 2,500 people watched the film on the festival's final evening, giving the director and the nine cast and crew members present a standing ovation when they appeared onstage. "7 Khoon Maaf" was originally scheduled for release on 21 January 2011, but was postponed a month to avoid conflicting with "Dhobi Ghat". The film was released on 18 February 2011 on about 700 screens across India. Reliance Home Entertainment released "7 Khoon Maaf" on DVD in March 2011 across all regions in a one-disc NTSC format. The Blu-ray and Video CD versions were released at the same time.  "7 Khoon Maaf" released to universal critical acclaim and Chopra's performance was singled out in particular, with many reviewers describing it as "a role of a lifetime". Aniruddha Guha of the "Daily News and Analysis" rated the film a four (out of five) and wrote, "For a filmmaker who has long established his hold over the craft, 7 Khoon Maaf is the only way forward – it pushes the envelope and takes you on a cinematic journey you may not experience in a Hindi film for a long time to come". She praised Chopra's performance: "Priyanka Chopra takes on a character that most of her contemporaries would shy away from and enacts it in a way that only she possibly can.
