Had my meeting with Carlos and holy crap, I'm totally blown away! My emails in GoHighLevel were going straight to spam no matter what I tried. In 60 minutes he fixed my DNS settings, set up proper DKIM/SPF/DMARC, explained domain warming step-by-step, and even gifted me his personal high-deliverability snapshot to import into my GHL account.
