Why Are My GoHighLevel Emails Going to Spam? Diagnosis Guide

The Three Causes of GHL Spam Problems

When GoHighLevel emails land in spam, the root cause falls into one of three categories:

1. Authentication failures — SPF, DKIM, or DMARC misconfigured or missing
2. Reputation problems — your domain or the sending IP has poor reputation
3. Content issues — your email content triggers spam filters

For a broader take on GHL deliverability issues, see our GHL deliverability problems guide. Let's diagnose which one is hitting you.

Step 1: Test Your Email Authentication

Before anything else, send a test email to check your authentication status.

Quick test: Send an email to [email protected]. You'll get an automated reply showing your SPF, DKIM, and DMARC results.

Detailed test: Use Mail-Tester. Send an email to the unique address they provide, then check your score. Anything below 8/10 needs attention.

What to Look For

Result	Status	Fix
SPF: pass	Good	None needed
SPF: fail	Critical	Add proper SPF record
DKIM: pass	Good	None needed
DKIM: fail	Critical	Configure DKIM in GHL
DMARC: pass	Good	None needed
DMARC: none	Warning	Set up DMARC record

Practitioner note: I see SPF failures in about 60% of GHL spam issues I diagnose. Most agencies set up the subdomain but forget to add their ESP's include statement to the root domain's SPF record.

Step 2: Check Your DNS Records

If authentication is failing, here's what to verify:

SPF Record

Your domain needs an SPF record that includes your sending service. If using custom SMTP with Mailgun:

v=spf1 include:mailgun.org ~all

If using LC Email, check GHL's documentation for their current include statement.

DKIM Record

DKIM requires a TXT record at a specific selector subdomain. In GoHighLevel:

1. Go to Settings > Email Services
2. Click on your domain
3. Copy the DKIM record they provide
4. Add it to your DNS

The record looks like: k=rsa; p=MIGfMA0GCSq... at a host like ghl._domainkey.yourdomain.com

DMARC Record

Add a DMARC record at _dmarc.yourdomain.com:

v=DMARC1; p=none; rua=mailto:[email protected]

See our GoHighLevel email authentication guide for complete setup instructions.

Step 3: Check Domain Reputation

Authentication passing but still hitting spam? Your reputation is the likely culprit.

Google Postmaster Tools

Set up Google Postmaster Tools for your sending domain. It shows:

• Domain reputation: Low/Medium/High
• IP reputation: For your sending IPs
• Spam rate: What percentage of recipients mark you as spam
• Authentication rates: SPF/DKIM/DMARC pass rates

If your domain reputation shows "Low" or "Bad," that's your problem.

Practitioner note: LC Email domains consistently show "Low" reputation in Postmaster Tools because the shared infrastructure means one bad actor affects everyone. This is the main reason I push agencies toward custom SMTP.

What Damages Reputation

• High spam complaint rates (above 0.1%)
• Hitting spam traps
• High bounce rates (above 2%)
• Sending to unengaged recipients
• Sudden volume spikes

Step 4: LC Email vs Custom SMTP

If you're using GoHighLevel's built-in LC Email and having spam problems, this is likely the core issue.

Why LC Email Causes Spam Issues

LC Email uses shared sending infrastructure. When other GHL users:

• Send to purchased lists
• Blast cold email campaigns
• Ignore bounces and complaints

Their bad behavior affects your reputation because you share the same sending pool.

The Fix: Custom SMTP

Switching to custom SMTP isolates your sending reputation. Options ranked by deliverability:

1. Mailgun — Best balance of price and deliverability
2. SendGrid — Good for higher volumes
3. AWS SES — Cheapest at scale

See our best SMTP for GoHighLevel guide for detailed comparisons.

Step 5: Content Issues

If authentication passes and reputation is fine, your content might be the problem.

Common Content Triggers

• Spam trigger words: "Free," "Act now," excessive capitalization
• Image-heavy emails: Less than 20% text is risky
• Too many links: Especially URL shorteners
• Missing unsubscribe: Required by law and expected by filters
• Mismatched From/Reply-To: Looks suspicious to filters

Test Your Content

Send your exact email to Mail-Tester before every campaign. Fix anything they flag.

Step 6: List Quality

Bad lists cause spam problems regardless of your technical setup.

Signs of List Problems

• Bounce rate over 2%
• Spam complaints over 0.1%
• Low open rates (under 10%)
• Lots of inactive subscribers

Fixes

1. Remove hard bounces immediately — GHL should handle this, but verify
2. Sunset inactive subscribers — No engagement in 90 days? Remove them
3. Use double opt-in — Prevents invalid signups
4. Validate your list — Tools like ZeroBounce or NeverBounce

The Diagnostic Checklist

Run through this systematically:

1. Authentication test passes (SPF, DKIM, DMARC)
2. DNS records correctly configured
3. Domain reputation is Medium or High in Postmaster Tools
4. Using custom SMTP (not LC Email) for critical sends
5. Content passes Mail-Tester at 8+/10
6. List hygiene maintained (bounces removed, engaged subscribers)
7. Unsubscribe link present and functional
8. Consistent sending volume (no sudden spikes)

Practitioner note: When agencies come to me with GHL spam issues, 80% of the time the fix is switching from LC Email to Mailgun and properly configuring authentication. The other 20% is list hygiene—they're sending to people who never signed up or haven't engaged in months.

When to Get Help

If you've worked through this checklist and emails still hit spam, you likely have a complex reputation issue that needs professional recovery.

Common scenarios that need expert intervention:

• Domain or IP is blacklisted
• Previous owner damaged domain reputation
• You need to continue sending during recovery
• Multiple subdomains and sending services to coordinate

If your GoHighLevel deliverability issues are costing you leads and revenue, schedule a consultation. I'll diagnose the exact problem and build a recovery plan specific to your setup.
