GOHIGHLEVEL ANSWERS & PROMPTS: PLAYBOOK T12 · DELIVERABILITY & DNS
AUTHOR: DANIEL HALLMAN
KEYWORD: DNS
What Usually Happens
Sending cold outbound campaigns from your main agency or client domain (`agency.com`) risks spam complaints that tank deliverability for everyday client invoices, proposals, and appointment confirmations.
How We Fix It in HighLevel
Register 2–3 secondary lookalike domains for cold prospecting, warm them for 14 days with SPF, DKIM, and DMARC configured, and sync only positive replies into your main HighLevel sub-account pipeline.
3-Step Implementation Checklist
- Keep your primary domain (`agency.com`) and its HighLevel LC Email subdomain (`mail.agency.com`) exclusively for opted-in leads and active clients.
- Set up 2–3 separate secondary domains for cold outreach with full SPF, DKIM, and DMARC records, capped at 25–30 plain-text emails/day per inbox.
- Forward only interested replies into your GoHighLevel pipeline via webhook so cold bounces never touch your primary LC Email reputation.

SAFE READ-FIRST WORKFLOW
Audit our email sending domains and set up a clean firewall between cold outreach and our main GoHighLevel sub-account domain: 1. Verify that our primary business domain and LC Email sending subdomain have valid SPF, DKIM, and DMARC records and are restricted to opted-in contacts. 2. Check that no cold unopted list imports are queued on the primary HighLevel LC Email domain. 3. Configure an inbound webhook workflow to create a HighLevel opportunity only when a prospect replies positively from our secondary outreach inboxes.
