Fix Mailchimp Domain Verification

I’m stuck at the “verify your domain” step in Mailchimp. I’ve added the required CNAME record at my registrar, yet Mailchimp still reports “verification failure.” I need someone who understands Mailchimp’s domain-verification flow, DNS records, and propagation timing to pinpoint what’s wrong, correct it if possible, and walk me through any registrar-side adjustments.

You’ll get temporary access to the registrar dashboard and my Mailchimp account (restricted to the domain settings area). Once your changes propagate, the green “Verified” badge in Mailchimp must appear; that’s the only acceptance criterion.

Please outline roughly how long you expect DNS propagation to take once the record is set correctly and let me know anything else you’ll need from me so we can get this wrapped up quickly.
