● Boomerang for Gmail → https://www.boomeranggmail.com/ PART 3: Always Include an Unsubscribe Link “But I don’t want people to unsubscribe.” ● Understandable — but if users can’t unsubscribe, they’ll hit the spam button. ● That’s far worse for deliverability than a clean opt-out. ● It’s also legally required in many regions. PART 4: Technical Setup (Do It Once, Then Forget It) ● Use your own domain (not the GHL shared domain) Options: ● Subdomain: mail.yourbrand.com – great for nurture + newsletters ● Full domain: yourbrandemail.com – useful for bulk sends or isolation ● Burner domain: Best protection for outreach or unknown list risk Why I Recommend Burner Domains: ● Burn one? You’re done. ● True story: I lost a $2K/month client because a Zapier email from my primary Gmail hit their spam. ● Client example: 10,000 cold emails triggered in one automation — domain reputation tanked. Verify & Set Up: ● SPF, DKIM, DMARC all configured in DNS ● Verify inside GHL domain settings PART 5: Warm-Up Your Domain (If New) If migrating from Kajabi, Mailchimp, etc. or setting up a new domain: ● Don’t blast immediately Sample warm-up plan: ● Day 1–3: 20–30 emails/day
