Best for a throwaway inbox with no sign-up
Guerrilla Mail is a free disposable inbox with no sign-up that deletes mail after an hour. Anyone who knows an inbox ID can open it, and the site shows ads.
Who Guerrilla Mail is for
- Fits if you need an address for a one-off confirmation link
- Works for developers who want a free inbox to test sign-ups against
Who Guerrilla Mail is not for
- Not for you if you need mail kept, as everything is deleted after 1 hour
- Skip it for anything private, since anyone with the inbox ID can open it
- Skip it if you dislike ads, as the site shows them and uses Google Analytics and AdSense
- Watch out: there's no spam folder

What is Guerrilla Mail?
Guerrilla Mail gives anyone a temporary email address on opening the site, with no registration. Mail is kept for one hour, and the inbox can send as well as receive. An optional paid add-on lets you point your own domain at it.
Worth knowing
- Anyone who knows an inbox ID can open that inbox, so it suits low-stakes messages only.
- Everything is deleted after an hour, and there is no spam folder.
- The site shows ads and uses Google Analytics and AdSense cookies, per its About page.
- The open-source part is the Go-Guerrilla mail server; the vendor does not say the whole website is open.
Key features
- No registration
- A random address is created when you open the site, and you can also choose your own address.
- Scrambled address
- Anyone who knows an inbox ID can read that inbox, so the site offers a scrambled alias as an extra layer of protection.
- Compose and reply
- The inbox has a compose window, so you can send from the disposable address.
- One-hour retention
- Messages are deleted an hour after they reach an inbox, or sooner if you delete them.
- API
- A public API is documented, and the vendor says its own front end uses it for everything.
