Guerrilla Mail alternative
Guerrilla Mail was a pioneer, but keeps the same 2006 premise: public address, visible inbox, messages vanishing within an hour. CoolMail is the evolution of the concept — an exclusive inbox with login, permanent, built for real sign-ups you'll reuse, with the verification code always highlighted.
