A statement from the Atlanta school says Phi Kappa Tau violated student conduct rules and didn't comply with sanctions imposed last fall.
The suspension was first reported by Georgia Tech's student newspaper, The Technique.
The fraternity came under scrutiny following reports about the email.
The student newspaper also published what it says are internal fraternity messages that include obscenity and describe sexual violence against women.
The national fraternity says the Tech chapter violated both university and fraternity policies and needs a break. A statement says the chapter failed to live up to fraternal ideals.
The group's disciplinary suspension ends in 2017.
