Is this inbox public like classic public disposable mail sites?
No. Mailfab keeps guest inboxes private to the browser that created them. We do not expose public inbox names that anyone can guess and open.

Disposable email FAQ
How this temp-mail flow works
Do I need to sign up first?
No signup is required. The default path is random-first, so you can open the page and start using a temporary inbox immediately.
How long do temp inboxes stay alive?
Guest inboxes use short expiration windows such as 10 minutes, 1 hour, or 24 hours. After expiry, cleanup removes the mailbox and its messages.
When should I switch to a full account?
Use a full account when you need longer-lived mailboxes, outgoing email, APIs, webhooks, or share links for teammates.
