The actress, who plays Sunita Alahan on the ITV soap, announced that she was leaving the social networking site on June 17.
"Tweets ta dees need another twitter break," she wrote. "Thanks for the banter the follows the support loved being back but now time to sort other stuff."
Explaining her decision to exit Twitter, Gulati confessed that she could no longer tolerate "psycho[s]" calling her things like "not British" and "the ugliest f**ker ever seen".
"Being racially abused on Twitter really shook me up," she told The Sun. "It felt like going back in time to the 1970s.
"It put me in mind of a psycho - like a horror movie. I just decided enough was enough.
"I tried to ignore it but it started to affect my confidence. Violent, vitriolic hatred gives people their moment in the spotlight. It beggars belief."
Gulati previously slammed the 'misogynistic' response from Twitter users to Sunita's affair with Karl Munro (John Michie), though she later claimed to revel in the controversy caused by the storyline.
