GlockApps Setup and Usage Guide

Why Use GlockApps

Google Postmaster Tools shows reputation but not actual placement. Your ESP shows delivery but not inbox vs spam. GlockApps fills the gap by testing where your emails actually land.

Key use cases:

• Pre-campaign validation
• Diagnosing sudden deliverability drops
• Verifying authentication setup
• Monitoring during IP/domain warmup
• Comparing infrastructure changes

Creating Your Account

1. Go to glockapps.com
2. Sign up with email
3. Choose plan (start with Personal at $59/month or use free trial)
4. Complete account setup

GlockApps offers a free tier with limited tests—useful for trying the tool before committing.

Running Your First Inbox Placement Test

Step 1: Get Your Seed List

In GlockApps dashboard:

1. Navigate to Inbox Insight → New Test
2. Copy the seed list addresses (50+ addresses across Gmail, Outlook, Yahoo, etc.)
3. Save these addresses—you'll send test emails to them

Step 2: Send Your Test Email

From your ESP or SMTP setup:

1. Create a new campaign or use your SMTP client
2. Paste the GlockApps seed addresses as recipients
3. Send the exact email you want to test (subject, content, links)
4. Use your actual sending domain and infrastructure

Important: Send from your real infrastructure. Testing from a different setup gives meaningless results.

Step 3: Wait for Results

GlockApps checks seed accounts for delivery:

• Initial results: 5-10 minutes
• Full results: 30-60 minutes (some providers delay)

Step 4: Analyze Results

The results dashboard shows:

Overall Inbox Rate: Percentage reaching inbox (vs spam or missing)

Provider Breakdown:

• Gmail: Inbox / Promotions / Spam / Missing
• Outlook: Inbox / Junk / Missing
• Yahoo: Inbox / Spam / Missing
• And others (AOL, iCloud, corporate)

Authentication Status:

• SPF: Pass/Fail
• DKIM: Pass/Fail
• DMARC: Pass/Fail

Practitioner note: Don't panic if a few niche providers show spam. Focus on Gmail, Outlook, and Yahoo—they represent 90%+ of most lists. If those three show inbox, you're likely fine.

Interpreting Results

Good Results

• 90%+ inbox across major providers
• SPF, DKIM, DMARC all passing
• No Gmail or Outlook spam placement

Warning Signs

• 70-90% inbox rate: Investigate specific failing providers
• Promotions tab (Gmail): Not ideal but not critical for marketing email
• One provider in spam: May indicate IP/domain blacklisting or authentication issue

Critical Problems

• Below 70% inbox rate: Major issue, pause campaigns
• Gmail or Outlook showing spam: Fix before sending
• Authentication failures: Stop and fix DNS records

Using DMARC Analyzer

GlockApps includes DMARC report parsing. Set up:

1. Add GlockApps DMARC address to your DMARC record:

v=DMARC1; p=quarantine; rua=mailto:[email protected]

2. Reports flow to GlockApps automatically
3. View in DMARC Analyzer tab

The analyzer shows:

• Who's sending as your domain
• Authentication pass/fail rates
• Unauthorized senders (potential spoofing)

Scheduled and Automated Testing

Auto-tests

Set up recurring tests:

1. Inbox Insight → Auto Tests
2. Configure schedule (daily, weekly)
3. Set seed list and expected sender
4. Receive alerts when results drop

API Access

For developers, GlockApps offers API testing:

curl -X POST "https://api.glockapps.com/v1/tests" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "Pre-campaign test", "wait_minutes": 30}'

Integrate into CI/CD or pre-send workflows.

Best Practices

Before Major Campaigns

1. Send test email to seed list 24-48 hours before campaign
2. Verify 90%+ inbox across target providers
3. Check authentication passes
4. If spam detected, investigate before sending

During Warmup

1. Test daily during first 2 weeks
2. Track inbox rate trend over time
3. Adjust volume if placement degrades
4. Document results for reference

After Infrastructure Changes

Test immediately after:

• ESP migration
• New sending domain
• IP change
• DNS record updates
• DKIM key rotation

Troubleshooting with GlockApps

If results show spam placement:

1. Check authentication: Are SPF/DKIM/DMARC all passing?
2. Check blacklists: GlockApps shows blacklist status
3. Check content: Run through spam content analyzer
4. Check specific provider: One provider failing vs all?

Content Analysis

GlockApps Spam Testing evaluates:

• Spam assassin score: Technical spam scoring
• HTML issues: Broken tags, missing attributes
• Link analysis: Suspicious URLs, shorteners
• Image-to-text ratio: Too image-heavy triggers filters

Access via Spam Testing in the dashboard.

Practitioner note: I run content analysis on every campaign template, not just new ones. One client's "approved" template suddenly triggered spam filters after Gmail updated their algorithms. Regular checks catch drift.

Pricing Considerations

Plan	Monthly Tests	Price	Best For
Personal	6,000	$59/mo	Small senders, occasional testing
Business	12,000	$99/mo	Regular campaigns, mid-volume
Agency	30,000	$199/mo	Multiple domains, high volume
Enterprise	Custom	Custom	Dedicated support, API access

Tests are consumed based on seed list size × test runs. A 50-address seed list uses 50 tests per run.

Limitations

GlockApps is valuable but not perfect:

• Seed accounts aren't your actual subscribers: Results are directional
• Point-in-time testing: Conditions can change after the test
• Promotions vs inbox: Gmail's Promotions tab detection isn't perfect
• Corporate email: Limited visibility into enterprise spam filters

Combine GlockApps with Postmaster Tools and ESP analytics for complete visibility.

If you need help interpreting GlockApps results or building a testing routine that catches problems before they affect your campaigns, schedule a consultation.
