Workspace email & sending spam to a 10k+ list

Hey all,

I have a secondary (backup) business/domain google workspace email address(es). This email is not tied to my main business domain, but I want to send to my targeted list from here..
(I'll most likely be using Atomic mail sender or something similar)

My question is: Assuming blocks & marked as spams, will this negatively impact my @domain workspace mail server entirely? I have some other addresses on there that I use for legit mailers that I don't want to be affected by this.

It might affects the other addresses
