GoHighLevel Email Reputation: How to Check and Improve Your Sender Score

Understanding Email Reputation

Sender reputation determines where your email lands. Mailbox providers track:

• Domain reputation — Attached to your sending domain, follows it everywhere
• IP reputation — Attached to the sending IP, determined by all senders using that IP
• Engagement signals — How recipients interact with your email

With GoHighLevel, reputation works differently depending on your setup:

Setup	Domain Rep	IP Rep
LC Email	Yours	Shared with all GHL users
Custom SMTP (shared IP)	Yours	Shared with ESP users on your pool
Custom SMTP (dedicated IP)	Yours	100% yours

How to Check Your Reputation

Google Postmaster Tools

Google Postmaster Tools is the most important reputation monitor for Gmail.

Setup:

1. Go to postmaster.google.com
2. Add your sending domain
3. Verify ownership (DNS TXT record)
4. Wait 24-48 hours for data

What you'll see:

• Domain reputation: Bad / Low / Medium / High
• IP reputation: Same scale
• Spam rate: Percentage of emails marked spam
• Authentication rates: SPF/DKIM/DMARC pass rates

Target metrics:

• Domain reputation: High
• Spam rate: Under 0.1%
• Authentication: 100% pass rates

Practitioner note: If Postmaster Tools shows Low or Bad domain reputation, you've got a real problem. This isn't fixable by switching ESPs—your domain itself is damaged and needs rehabilitation through consistent good sending.

Your ESP Dashboard

If you're using custom SMTP, check your provider's dashboard:

Mailgun:

• Logs > Events shows delivery status
• Analytics shows bounce and complaint rates
• Reputation section shows sending health

SendGrid:

• Statistics shows delivery metrics
• Suppressions shows bounces and complaints
• Email Activity shows individual email status

AWS SES:

• Reputation dashboard shows bounce/complaint rates
• Account sending statistics

Key metrics to track:

• Bounce rate (should be under 2%)
• Complaint rate (should be under 0.1%)
• Delivery rate (should be over 95%)

Blacklist Checking

Run your sending domain and IPs through blacklist checkers:

• MXToolbox Blacklist Check
• MultiRBL

Check both:

• Your sending domain
• Your sending IPs (get these from your ESP)

If you're on major blacklists (Spamhaus, Barracuda), you need removal before reputation can improve.

Microsoft SNDS

For Outlook/Microsoft reputation:

1. Go to SNDS
2. Register your sending IPs
3. View reputation and trap hits

Microsoft doesn't show domain reputation directly but does show IP reputation and spam trap hits.

What Damages Reputation

High Bounce Rates

Bounces signal you're sending to bad addresses:

• Over 2% bounce rate triggers warnings
• Over 5% can cause blocks
• Consistent high bounces indicate list quality problems

Fix: Clean your list before sending. Remove addresses that bounce. Use validation services like ZeroBounce or NeverBounce for imports.

Spam Complaints

Complaints are the most damaging signal:

• Over 0.1% triggers Gmail warnings
• Over 0.3% can cause severe filtering
• Over 0.5% risks account suspension at most ESPs

Fix: Only email people who opted in. Make unsubscribe obvious. Don't send too frequently. Remove unengaged subscribers.

Spam Traps

Spam traps are email addresses that don't belong to real people:

• Pristine traps: Never subscribed, indicate purchased lists
• Recycled traps: Abandoned addresses, indicate poor list hygiene
• Typo traps: Catch common typos like @gmial.com

Fix: Never purchase lists. Remove addresses that haven't engaged in 90+ days. Validate new signups.

Authentication Failures

Failed SPF, DKIM, or DMARC damages reputation:

• Gmail marks failures in Postmaster Tools
• Consistent failures signal domain compromise or misconfiguration

Fix: Verify all DNS records are correct in GHL and your ESP. Test with Mail-Tester before campaigns.

Practitioner note: I regularly see agencies with perfect list hygiene but damaged reputation—turns out their DKIM was misconfigured for months. Check authentication first. It's the easiest fix and the most common oversight.

Sending to Unengaged Subscribers

Low engagement tells mailbox providers your mail isn't wanted:

• Recipients who never open
• Recipients who don't click
• No replies

Fix: Segment by engagement. Stop sending to people who haven't opened in 90 days. Re-engage or remove them.

How to Improve Reputation

Step 1: Fix Authentication

Run a test to [email protected] or use Mail-Tester.

All three should pass:

• SPF: pass
• DKIM: pass
• DMARC: pass

If any fail, fix your DNS records. See our GHL authentication guide.

Step 2: Clean Your List

Remove:

• Hard bounces (should be auto-suppressed, verify)
• Spam complaints (check ESP suppression list)
• No opens in 90 days
• Role-based addresses (info@, sales@)

Validate remaining addresses with a cleaning service if you have doubts.

Step 3: Reduce Volume Temporarily

During reputation recovery:

• Cut volume by 50-75%
• Send only to most engaged subscribers
• Avoid cold contacts entirely

This concentrates positive engagement signals.

Step 4: Focus on Engagement

Engagement heals reputation. During recovery:

• Send content recipients actually want
• Encourage replies (real signals of wanted mail)
• Make sure opens and clicks happen

Step 5: Monitor Progress

Check Postmaster Tools daily during recovery:

• Watch for reputation improvement
• Verify spam rate stays low
• Confirm authentication holds at 100%

Recovery timeline:

• Minor damage: 2-4 weeks
• Moderate damage: 4-6 weeks
• Severe damage: 6-8 weeks

The LC Email Problem

If you're using LC Email, your IP reputation is shared with all GHL users. You can't fully control it.

Signs LC Email is the problem:

• Your list is clean and engaged
• Authentication passes
• But reputation is still Low/Bad

The fix: Switch to custom SMTP for dedicated reputation. See best SMTP for GHL.

When to Use a New Domain

Sometimes domain reputation is too damaged to recover:

• Multiple blacklist appearances
• Months of Low/Bad in Postmaster Tools
• ESP suspended your account

Starting fresh means:

1. Register a new sending domain (subdomain of your main)
2. Set up fresh authentication
3. Connect to custom SMTP
4. Warm up from zero

See our warmup guide for new domain procedures.

Ongoing Reputation Monitoring

Once reputation is healthy, maintain it:

Weekly:

• Check Postmaster Tools for any changes
• Review ESP bounce and complaint rates
• Verify authentication still passes

Monthly:

• Run blacklist check
• Review engagement trends
• Remove 90-day inactive subscribers

Before every campaign:

• Verify authentication
• Check recent reputation status
• Confirm list was cleaned

If your GHL email reputation is damaged and affecting your business, schedule a consultation. I'll diagnose the root cause and build a recovery plan specific to your situation.
