The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The disposable inbox is free, and using your own domain is $9.99 a year. |
| Free plan and trial | A | Free outright, with no account, so there's no cap to reach on a throwaway inbox. |
| Features | C | Receiving, replying and an API. It does the throwaway-address job fully, which is a smaller job than a mailbox, and it keeps nothing past an hour. |
| Ease of use | B | Open the page and you have an address. Nothing to set up. |
| Platforms and integrations | C | Web only, with an API for scripts. No phone or desktop apps are listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
