Headlined "a potential death warrant for Lewis", it accused Mercedes of "systematic sabotaging" of Hamilton, his car, tyre and race strategy and mental health.
Hamilton said on Thursday he had not seen the email and called for "support, not negativity". He also defended Russell from online abuse.
Wolff, accused in the email of being vindictive and acting "like a scorned wife", told reporters the perpetrator should "get a shrink".
He said Hamilton had been part of the team for 12 years, that he and the Briton were friends and trusted each other while Mercedes also needed both cars fighting for constructors' championship points.
"We're going to end this on a high, we want to celebrate the relationship," he said.
"We want to be successful with the most iconic driver the sport has ever had...I totally respect the reasons for him going to Ferrari, there is no grudge, no bad feeling."
Ferrari boss Fred Vasseur, sitting alongside Wolff at Barcelona's Circuit de Catalunya, concurred.
"How you could imagine that a company with 1,500 people working night and day, pushing like hell to bring upgrades each race, we could damage one of our cars? This is completely irrational," he said.
"Nobody in the paddock could do something like this."
