A temp mail alternative with a private inbox
“Temp mail” sites give you an address in a second, without an account. nerdbox asks for one, so that your inbox is yours alone. Here is what that changes, from the services’ own pages.

| Who can read the inbox (sources 2, 3) | Not stated on the pages read | You alone: each inbox has a password generated for you | Anyone who knows the inbox ID | You alone, signed in to your account |
| How long mail is kept (sources 1, 3, 4) | 1 to 2 hours, according to its iPhone app | 7 days | 1 hour | As long as the address lives: 24 hours, up to 7 days |

When a temp mail site fits better
- You want an address at once, and creating an account is too much.
- You need to write a mail (Guerrilla Mail has a page for it).
When nerdbox fits better
- You come back often: your addresses wait in your space, with a name for each.
- The mail holds a code nobody else should see.
- You want the code ready to copy, as a notification on your phone, or on the page with the Chrome extension.
