I am using parse.com and Mailgun to send emails. But when I tried to send email I see the error that says

"The domain is unverified and requires DNS configuration. Log in to your control panel to view required DNS records\\"\n}\",\"data\":{\"message\":\"The domain is unverified and requires DNS configuration. Log in to your control panel to view required DNS records\"

I could see that my DNS is not verified in Mailgun dashboard as well.

If I use a custom domain I can do these configurations with the domain provider panel.

But I am using default xxx.parseapp.com as my domain for now.

How to do the setting for this scenario. I couldn't find any place to do the TXT settings in parse.com
