Disposable email providers and the domains they use

A disposable email provider is a service that creates a temporary inbox in seconds, with no password and no signup. People use one to get past a form or a gated download without giving a real address. Temp-Mail, Mailinator and 10MinuteMail are common examples.

Far more than the list on this page. A single provider can rotate through hundreds of domains, and new ones appear every day. The Giggal verification service checks addresses against a list of more than 100,000 disposable domains that is rebuilt every six hours.

No. Gmail, Outlook, Hotmail, Yahoo and iCloud are permanent mailbox providers, not disposable services. They are not on any disposable list. An address on one of these domains can still be invalid if the mailbox does not exist, which is a separate check.

Check each address at signup. If the domain is disposable, ask the person for a different address before the account is created. You can automate this on your forms with the email validation API, which answers in real time.

This page shows the well-known domains. The full list is held by the verification service and updated continuously, so the reliable way to use it is to check addresses through the API rather than copy a static file that goes stale.

A disposable provider gives you a throwaway inbox that is meant to be abandoned. An alias service like addy.io or 33Mail forwards mail to your real inbox and lets you turn the alias off later. Some alias domains are on disposable lists, because the person can cut off your mail at any time. Others are not, because they forward to a real inbox that someone reads.
