Domain whitelist

I am having a difficult time trying to figure out how to get Whitelisted. I have tried posted to already existing conversations with no reply. I have no idea if it is even going to where it should be. I am not a big fan of this format y’all have gone to. Not being able to get in touch with someone has been a issue for me. I really like the Sketchup software and use it frequently for projects in my shop for students. So I don’t want to loose the ability to have it as a tool for that. With that being said I guess if I can’t get thru this way and there does not appear to be any other way to get tech support, I will have to go back to what I used to do.
The domain I need whitelist “greatplains.edu” and “my.greatplains.edu”

Thanks for any help
