GoHighLevel Email Deliverability 2025: SPF, DKIM, DMARC + Warmup (No Spam)

Struggling with emails landing in Promotions or Spam in GoHighLevel? In this step-by-step guide I show what actually works in real campaigns: content that gets replies, unsubscribe best practices, dedicated/burner domains, DNS setup (SPF, DKIM, DMARC), and safe warmup—plus when to use cold-email tools vs. GHL nurtures. This follows my written playbook and checklists.

What you’ll learn

The mindset: you’re not entitled to the primary inbox—and why content drives ~90% of outcomes.

Fast content fixes: subject lines, preview text, short plain-text structure, clean CTA, and common spam triggers to avoid.

Unsubscribe links: why they protect your domain (and legal notes).

Technical setup once, then forget it: custom/dedicated or burner domains + SPF, DKIM, DMARC inside GHL. (DMARC is now strongly recommended by GHL and email providers.)
