Question 1

What is a temporary email?

A temporary email (also called disposable email or throwaway email) is an email address that works for a short time and then self-destructs. You can receive emails but the address expires automatically. GoneBox inboxes last 1 hour by default.

How long do emails last?

Accepted Answer

By default, 1 hour. On the Startup plan you can extend to 24 hours, and Enterprise allows up to 7 days.

Question 4

Can I send emails from GoneBox?

No. GoneBox is receive-only. You can receive emails at your temporary address but cannot send outgoing emails.

Is using a temporary email legal?

Accepted Answer

Yes. Using a temporary email to protect your privacy is perfectly legal. However, using any email service for fraud, harassment, or illegal activity is prohibited by our terms of service.
