Deeming Saturday delivery “no longer sustainable,” The U.S. Postal Service announced Wednesday it will eliminate Saturday delivery of mail by Aug. 1.

Saturday is the lightest mail delivery day by volume and many businesses are closed on Saturdays, according to the U.S. Postal Service.

Even though there will not be Saturday delivery, with the exception of Express Mail, local post offices that are currently open on Saturday would remain open. Mail accepted at Post Offices on Saturdays will be processed on Monday.

A 2012 Rasmussen poll and a 2010 Gallup poll on mail delivery found that the majority of U.S. residents surveyed were ok with eliminating Saturday delivery.
