Using shared default tracking links or embedding invisible open-tracking pixels in first-touch outreach triggers Gmail and Outlook spam filters across the board.
Configure a custom CNAME tracking subdomain (`track.yourdomain.com`) in HighLevel, turn off open-pixel tracking on cold or reactivation sequences, and measure engagement through plain-text replies instead.
Verify and configure custom link tracking domains for our GoHighLevel sub-account: 1. Check if the sub-account is still using a shared default tracking domain instead of a branded CNAME subdomain. 2. Generate the exact CNAME record for track.<clientdomain> and verify authoritative DNS resolution over UDP/53. 3. Audit active email workflows and recommend disabling open-rate tracking pixels on first-touch reactivation campaigns.
# 1. MCP Tool Call (ghl-onboard-mcp)
{
"tool": "dns_verify_tracking_cname",
"arguments": {
"location_id": "<YOUR_LOCATION_ID>",
"tracking_host": "track.clientdomain.com",
"verify_ssl": true
}
}
# 2. Or run via ghl-onboard Rust CLI
ghl-onboard dns verify-tracking --domain clientdomain.com --host track
Keep your primary root domain strictly for opted-in clients, billing, and calendar invites, and run cold outreach from 2–3 secondary domains capped at 30 plain-text emails per inbox per day.
