Guerrilla Mail is a free disposable email address service launched in 2006. Visitors are automatically assigned a random email address upon visiting the site.
Features
Guerrilla Mail randomly generates disposable email addresses.[1] Disposable email addresses may be used as a means of spam prevention.[2] They may also be used if the user does not wish to give a real email, for example if they fear a data breach. Emails sent to addresses are kept for one hour before deletion. The site offers some choice of email domain names.[2][3]
History
Guerrilla Mail was founded in 2006, in Chicago.[4]
In December 2013, a Harvard College sophomore and Quincy House resident Eldo Kim used Guerrilla Mail to send a bomb threat to offices associated with Harvard, including the Harvard University Police Department and The Harvard Crimson, in order to delay a final exam.[5][6][7] It was alleged in an affidavit that the student accessed Guerrilla Mail through Tor, a fact that might've been given away in the IP address present in the email header.[8][9]
In June 2017, it was revealed through court documents that the FBI used a social engineering technique known as phishing to target a Guerrilla Mail user. The case was unique, as it was the "first public example of the feds using a controversial update to a law allowing searches on users of anonymizing tools like Tor".[10][11]
As of November 4, 2020, Guerrilla Mail stated on Twitter that their site had been taken down by their hosting provider, OVHCloud, due to a law enforcement request which OVHCloud refused to provide details about.[12]
However, as of August 20, 2023 sending email from Guerilla Mail is once again suspended. Visitors receive the same message "sending mail has been suspended for today". There X social media page says sending mail is suspended until further notice. https://x.com/GuerrillaMail/status/1693224645577576796
