Accessing Website Control Panel

We are looking to set up a G Suite account for our website,
Following the instructions to verify our website we need to access the website control panel to update / Add MX Records.

I have not been able to find a way to access the control panel using the webstore manager, if this something that can be accessed through nitrosell or if there another method to access it?

Hi Grant,

Changes to MX Records, CNames etc. have to be added through the support team directly. Please open up a ticket on our portal with the records that you would like to add and we will assist.
