Spec score 7.6 #27 of 44 in Temporary email services

What it is

TempMailPortal provides temporary inboxes for receiving permitted, low-stakes messages, reducing spam, and testing applications you control. Its web inbox can be used without signing in or creating an account. Messages normally expire within 24 hours, though they can be deleted sooner from the current inbox. The service receives ordinary text and HTML email but cannot compose, send, or reply to messages.

The website displays attachment filenames only; the Android app can view supported files or save attachments that remain available. Android use has different daily allowances for signed-in and guest users. The service is free and available on the web and Android. Its privacy policy says message content is not sold or used to build advertising profiles. However, temporary website addresses are not password-protected, so anyone who knows or guesses one can view its mail. Public developer API access is being retired, making old curl examples and API keys unsupported integration methods. The service prohibits fraud, impersonation, ban evasion, spam, mass registrations, and accounts users lack permission to create.

Who it suits

TempMailPortal suits people who need a short-lived inbox for optional, low-risk sign-ups or developers testing their own applications. It is not suited to sending email or handling sensitive messages through website inboxes.
