No, there are hundreds of GMF members with .net domains, largely verizon.net but comcast and others too. So that of itself is not the problem.
It is possible that Groups.io has a block on that domain if it had been troublesome in the past, but I'd more likely suspect some syntactical error to get "Invalid email" as the error. You may need to report it to [email protected] to find out what the problem is.

I don't approve memberships with email addresses at mypacks.net. It's a service that provides anonymous, disposable email addresses. And while not "black hat," it has more association with spam than the average email provider.
