Why was my signup refused?

mailinator.com is a disposable email domain

mailinator.com is on our list of disposable email domains. Its inboxes are throwaway addresses that anyone can open, so many apps refuse them. See what we have recorded about mailinator.com.

How to sign up another way

  • Sign up with a permanent address, from your own email provider or from work.
  • If you use a VPN, a proxy or a cloud server, turn it off and sign up from your home or mobile connection.
  • If many people on your network signed up at once, try again later.
  • If it still fails, write to the app's support team. Only the app can let you in.

What this page cannot show

This page shows what we know about an email domain on its own. Each app sets its own rules. An app can also look at the network you signed up from and at how many signups came from it. We never show an app's settings or its records of your signup.
