The final set of emails belonging to former Secretary of State Hillary Clinton will be released at 2300GMT Monday, the State Department said.
"Today's production will be our fourteenth and final production of former Secretary Clinton's email set," according to spokesman John Kirby.
"There are no upgrades to top secret in tonight's production."
He also said that the department would post online a redacted document that National Security Agency deemed "top secret" last summer.
Announcing that the amount of the last batch of emails would be 3,800 pages, Kirby said one of the two emails was to be released under the lesser "secret" category.
The email was not classified when it was transmitted.
The other email between Clinton and President Barack Obama will be withheld form the release Monday.
"This one additional e-mail, which is being withheld in full today, is a reply to an email chain that was already denied in full last month," Kirby said.
The two emails are at the center of an ongoing dispute between the U.S. intelligence community and the State Department.
The intelligence community had pushed for the exchange on North Korea's nuclear program to be declared "top secret".
With Monday's release, the State Department will have released between 52,000 and 53,000 of Clinton's emails while she served as secretary of state.
The department withheld 22 emails last month because they included "top secret" information. Those emails were related to the CIA's drone program.
