Is it possible to appeal Google Workspace spam blocks?

I have an email/domain that I've had but haven't used much for the past few years and I'm trying to start using it on Google Workspace. When I get to the end of the signup flow I get a message informing my that they won't let me sign up because they believe the domain will be used for spam[0] (which it emphatically will not be).

I don't see any support options, is there anything reasonable I can do or am I just SOL and not allowed to pay for Google's tools?

Google works hard to keep spammers from using Google Workspace. As part of this effort, we refuse to create domains that we believe will be used for spam. Unfortunately, we may sometimes refuse legitimate signups. If you've been stopped in error, we're sorry for the inconvenience.

Google weighs several factors when evaluating registration attempts, including the number of domains that have been created from that location and whether the domains have just been created or have a good reputation on the internet. Users trying to create a lot of domains, who are using shared computers or computers infected with malware; or signing up for low reputation domains may hit this limit.
