Use case
A temporary inbox that behaves like a real mail client
Most throwaway inboxes give you a raw message dump. This one gives you folders, search, spam scores, attachment handling and keyboard shortcuts — then cleans itself up.

Start as a guest
No sign-up needed for your first mailbox. Add an account later and keep everything.
Choose the lifetime
24 hours on Free, up to 90 days on Pro, or a custom retention window on Campus.
Real folders
Inbox, starred, archive and trash — plus search across subject, sender and body.
Spam verdicts
Each message carries a score and verdict so you can spot a bad sender immediately.
What a temporary inbox is good for
Sign-up confirmations, one-off downloads, trial accounts, event registrations and any form that wants an address before it earns one.
- Confirm a sign-up without adding another sender to your main inbox
- Test your own product's transactional email end to end
- Share a read-only address for a short campaign or event
What it isn't for
Don't use a disposable address for anything you need to recover later — password resets on important accounts, banking, or legal correspondence. Once a mailbox expires, its messages are gone.
