Make a fresh inbox
Open the guest page and use the generated address for a single flow or short test.
Throwaway email guide
Create a throwaway email inbox for one-off messages.
A throwaway email address is useful when you need a temporary place to receive mail, then move on. Mailfab makes that flow immediate with a guest inbox, while keeping longer-lived automation in signed-in workspaces.
Let expiry clean up
Guest inboxes support short windows such as 10 minutes, 1 hour, or 24 hours.
End the session
When the job is done, end the guest mailbox session or replace it with a new random address.
How to make one
The safest throwaway email flow is simple.
Use a new temporary address for each short-lived task, keep the inbox open while you wait for the message, and avoid using that address for anything you will need months from now.
- Create a new guest inbox for the specific task.
- Copy the address into the signup, invite, or verification form.
- Read the incoming message and finish the flow while the inbox is available.
Good boundaries
Temporary does not mean permanent account identity.
A throwaway email should not be the address for banking, billing, or an account you may need to recover. When an inbox expires or is deleted, future recovery messages sent there are no longer useful inside Mailfab.
- Use permanent email for critical accounts.
- Use Mailfab for short-lived verification, QA, and testing.
- Move to signed-in mailboxes when API keys, webhooks, or sharing are needed.
