Have you set up some authorized recipients for the sandbox domain?

A sandbox subdomain of mailgun.org. Example: sandboxXX.mailgun.org. This option allows for quick testing, without having to setup DNS entries. This domain is provisioned automatically with every new account. But you can send only to authorized recipients.
