How it works
Open the tool and wait a moment while Ontool creates a disposable address through the first available provider.
Copy the address and use it wherever you need a throwaway inbox. Do not use it for sensitive accounts or password resets.
Leave the page open. The inbox checks for new messages every eight seconds while the tab is visible.
Select a message to read it in a sandboxed HTML view, or switch to the plain-text version. Choose New address whenever you want to start over.
Frequently asked questions
What is a temp mail address?
It is a short-lived email address you can use for signups, trials or other places where you do not want to share your main address. This page gets the address from a third-party temporary-email provider and shows the messages in one inbox.
Is this inbox private?
Treat it as disposable, not private. Messages are fetched from a third-party provider through Ontool’s server, the provider may retain them, and the address should not be used for banking, password resets or other sensitive accounts. Ontool does not provide end-to-end encryption.
How long does the address last?
Provider retention varies and is outside Ontool’s control. The saved inbox session lasts up to one hour in this browser, and you can create a new address at any time. If the page is closed, the provider may still keep the inbox, but Ontool does not guarantee that it will come back.
Can I receive attachments?
Message summaries can indicate that an attachment exists, but this first version does not download or preview attachments. Use the plain-text or HTML body to read the message itself.
Why did my address change?
Ontool tries several providers in order. If the provider behind your current inbox stops responding, the page can move you to a new address from another provider. Messages sent to the old address will not appear in the new inbox.
Can I send email from this address?
No. This tool only receives mail. It does not provide an SMTP account, outbound sending, a calendar or a permanent mailbox. Use a normal email service when you need to reply or send a message.
