If your cold emails are landing in spam, it’s not random — it’s email deliverability. This guide breaks down how to run and audit your email deliverability in 2025. And with Piixoo – Best Cold Outreach Email Automation Software , you get built-in tools to manage, score, and optimize your deliverability from day one — all in one platform.
🔍 What Is an Email Deliverability Audit?
An email deliverability audit is a deep check-up of everything that affects whether your emails land in the inbox — or vanish into spam.
It helps you:
- Detect technical issues (DNS, SPF, DKIM, DMARC)
- Evaluate domain and IP reputation
- Measure inbox placement
- Identify blacklistings
- Analyze email content and sending patterns
🛠️ Step-by-Step: How to Run an Email Deliverability Audit
Here’s a simple framework to audit your own deliverability:
1. 🔗 Check Your Domain Configuration
- Make sure SPF, DKIM, and DMARC are correctly set
- These records authenticate your emails and protect against spoofing
- Missing or misconfigured DNS entries = spam risk
2. 📊 Measure Your Inbox Placement
- Run inbox tests across Gmail, Outlook, Yahoo, and others
- See how often your emails hit Primary, Promotions, or Spam
3. 🛑 Verify You’re Not Blacklisted
- Use blacklist checkers to see if your domain or IP is flagged
- Get alerts if you’ve been listed
4. 📩 Analyze Bounce Rates
- A high bounce rate damages your sender reputation
- Remove invalid emails from your lists regularly

5. 🧬 Review Email Content
- Avoid spammy words, too many links, or suspicious formatting
- Check subject lines, CTAs, and structure
6. ⏱️ Evaluate Sending Behavior
- Are you sending too fast? Too often? From a cold domain?
- Gradual warm-up is essential for new senders
