How to send email from my domain?

Sending email from your domain is possible once you upgrade your site to "Hosted Domain" offering (Power User).

Once you do that, you will need to set your DNS settings to point to our nameservers (details will be given in your RYO admin panel)

Then you need to login to the RYO admin and go to Setup -> Sending. There you will need to enter your recaptcha settings, which you get from https://www.google.com/recaptcha/
