The U.S. Postal Service said Thursday it was considering closing more than half of its 487 mail-processing facilities, eliminating 35,000 mail-processing positions and slowing mail delivery service, its latest move in a fight to remain solvent.

“We simply need fewer facilities to process less mail,” Megan Brennan, the chief operating officer of the Postal Service, said at a press conference.

As more people communicate online instead of through paper and pen, the country’s Postal Service has been losing money and says it now has more capacity than needed to process mail. The mail service, which says it lost more than $9 billion last year, has already proposed ending Saturday delivery service–a change that Congress has so far resisted. The Postal Service now wants to close more facilities and slash its work force to make up for ongoing declines in mail volumes.

Earlier this year, the Postal Service said it would study as many as 2,000 post offices for possible closure. Of the 1,200 ultimately selected, as of July, 300 were still being studied, 280 had closed, and 620 were in various stages of closing. In March, the mail service said it would eliminate 7,500 managers and shut seven district offices. Then, in July, the Postal Service said it would consider closing 3,653 post offices, mostly in rural areas.
