In an interview with the Daily Mail, Stephen Dymond's son Carl Woolley, 39, said his father was "distraught" after failing a lie detector test on the popular talk show.
"Given the gravity of recent events we have chose to end production of The Jeremy Kyle Show", McCall said.
In the email, witnessed by a journalist from Buzzfeed, ITV head Carolyn McCall says that the decision to "suspend both filming and broadcasting of the show" was "not in any way a reflection on the show, but the best way we can protect the show and the production team from the reaction we expect to this death".
Monday morning's episode of the Jeremy Kyle Show did not air and ITV has now wiped all episodes of the programme from its on-demand service the ITV Hub, and episodes will not air on ITV2.
Mr Walker said: "It's cruel".
Ms Callaghan said that just before they went on the show, Mr Dymond had convinced her he had not cheated. He said: "I'm satisfied Steve meant to kill himself".
"The death is not being treated as suspicious and a file is being prepared for the coroner". Autopsy results would be needed to further determine the cause, and it's expected that an inquest will be opened.
It emerged on Tuesday that Mr Dymond had been the subject of an arrest warrant after he failed to attend a court hearing for non-payment of a fine.
After he failed to attend the hearing, a warrant was issued for his arrest.
The Jeremy Kyle Show guest who died days after recording the episode reportedly split from his partner following an attempt to prove he was not a cheat.
The programme has yet to return to the air with all episodes suspended and all filming put on hold.
An Ofcom spokesman said: "This is clearly a very distressing case".
A particularly tragic story has emerged out of the U.K.in the past week concerning the popular daily talk show The Jeremy Kyle Show, which is akin to US talk shows hosted by Maury Povich and Jerry Springer.
Claims made by the apparent former employee have been reported by BBC Newsbeat about the ITV programme, which has been taken off air indefinitely.
After Mr Dymond's death, ITV suspended filming and took all planned episodes off the air, adding that the episode featuring Mr Dymond would never be screened.
The programme has had its regular daytime morning slot on ITV since 2005. He also alluded to the two former Love Island guests, Mike Thalassitis and former Miss Great Britain Sophie Gradon, who died earlier this year in unconnected incidents.
