Hi Goran –
Sorry for the delayed response here. The issue has been fixed. Can you contact me for a beta test? travis [at] mailgun [dot] com
Thanks!

You first need to install the Plugin. Then go to the Plugins section in the Admin area. From there, add your Domain and API key to the settings. Now, all emails that would typically use the WordPress mail functions will go out through Mailgun instead. Contact support [at] mailgun [dot] com for more help.
