Providers/Guerrilla Mail
Guerrilla Mail
Guerrilla Mail is a classic temporary email service with rotating public domains. Inboxes expire quickly and require little or no registration.
Guerrilla Mail domains show up in trial abuse, spam account creation, and bots that need a working inbox for a few minutes only.
