Guerrilla Mail review

Guerrilla Mail has run since 2006 and is the most flexible of the free disposable inboxes. A random address is ready as soon as the page loads, and you can switch between 11 domains, including sharklasers.com, grr.la, pokemail.net and several guerrillamail domains, which helps when a site blocks one of them. Unlike most throwaway services, it also has a Compose tab, so you can send mail from the disposable address, plus Scramble Address and Forget Me buttons to reset the inbox. The site reports processing more than 21 billion emails. If you own a domain, you can point it at Guerrilla Mail for $9.99 a year and choose whether the mail is private to you or open to everyone, paid by Bitcoin or PayPal. The weaknesses are typical of the category: nothing is forwarded to your real inbox, the page carries ads, and an address on a shared domain is no place for an account you need to keep.
