Cold email is ruining my business

I literally don’t know what to do no more. I’ve warmed up 2 email domains for 4 weeks, DNS settings are configured correctly, I’m using text only outreach no links or images. And I just keep ending up in spam it’s actually ridiculous. What do I do ? Also my industry is CPG so I’m only sending 20 emails 10 per domain yet I go to spam still. I’m at the point now I am using 4 personal emails and sending 5 emails per day on each scheduling them in advance 30+ minutes apart from each email. What am I doing wrong tho like it has to be bad luck or something at this point.
