Core concepts
Guest inboxes
Created without an account, authorized by a private token stored in your browser. They expire after a set time and can be extended a limited number of times.
Saved inboxes
Once you create a free account, you can save a guest inbox to keep it permanently and access it from any device.
Expiration
Every inbox has a countdown shown in the interface. When it reaches zero, the address and its messages are permanently deleted.
Plans & limits
Your plan determines message retention and the number of active inboxes you can have. See the pricing page for details.
Using the API
TempMail has a documented REST API for creating inboxes and reading messages programmatically — useful for testing signup flows or automating anything that needs a real, receivable email address.
