Sai, 28, was seen less during promotion of the film as she was busy with her Marathi project.
"Sorry I'm shooting and have no access to the net. I am overwhelmed with your response after watching 'Hunterrr'. Thank you and love you," she tweeted.
In the Harshvardhan Kulkarni-directed film, which released last Friday, Sai played a Marathi housewife who gets attracted to a sex addict (played by Gulshan Deviah).
The humour-laced drama about the life and times of the sex addict also stars Radika Apte and Veera Saxena in prominent roles.
