There are 62,320 emails sent to or from her firstname.lastname@example.org address, which is an average of 296 a week, or nearly 1,300 a month. Clinton will later claim that roughly half of these (31,830) were private in nature and she will delete them before investigators can look at them.
The Washington Post will later explain, “Most of her emails were routine, including those sent to friends. Some involved the coordination of efforts to bring aid to Haiti by the State Department and her husband’s New York-based Clinton Foundation—notes that mixed government and family business, the emails show. Others involved classified matters. State Department and Intelligence Community officials have determined that 2,093 email chains contained classified information. Most of the classified emails have been labeled as ‘confidential,’ the lowest level of classification. Clinton herself authored 104 emails that contained classified material, a Post analysis later found.” (The Washington Post, 3/27/2016)
Twenty-two of her emails will later be determined to be classified “top secret” or even higher than top secret in some cases, due to the mention of highly secretive Secret Access Programs (SAP). (The New York Times, 1/29/2016)
