Can't Figure Out Google Workspace

I'm trying to launch a business, so I signed up for a Google Workspace account. Now I'm trying to send test emails and they keep getting delivered to spam. It says the email is still authenticating, but it's been more than 72 hours. I tried Mailtester and this is what came up. Totally clueless on what to do.
