Emails from Instagram, built directly into the app, is only one official way for Instagram to contact you. You can view your emails by going to Settings, then Security, then Emails from Instagram, or check your inbox for emails from firstname.lastname@example.org.
In August 2017, reports surfaced that a bug in Instagram's developer tools had allowed "one or more individuals" to gain access to the contact information, specifically email addresses and phone numbers, of several high-profile verified accounts, including its most followed user, Selena Gomez. The company said in a statement that it had "fixed the bug swiftly" and was running an investigation. However, the following month, more details emerged, with a group of hackers selling contact information online, with the affected number of accounts in the "millions" rather than the previously assumed limitation on verified accounts. Hours after the hack, a searchable database was posted online, charging $10 per search. The Daily Beast was provided with a sample of the affected accounts, and could confirm that, while many of the email addresses could be found with a Google search in public sources, some did not return relevant Google search results and thus were from private sources. The Verge wrote that cybersecurity firm RepKnight had found contact information for multiple actors, musicians, and athletes, and singer Selena Gomez's account was used by the hackers to post naked photos of her ex-boyfriend Justin Bieber. The company admitted that "we cannot determine which specific accounts may have been impacted", but believed that "it was a low percentage of Instagram accounts", though TechCrunch stated in its report that six million accounts were affected by the hack, and that "Instagram services more than 700 million accounts; six million is not a small number". 2b1af7f3a8
