Email Deliverability Score

Enter your domain and get an instant grade on your email authentication setup. We check SPF, DKIM, DMARC, MX records, and blacklists.

Understanding Your Score

Your deliverability score is based on five key checks that receiving mail servers use to evaluate your emails:

  • SPF (20 points): Verifies which servers are authorized to send email on behalf of your domain.
  • DKIM (20 points): Confirms emails have not been tampered with in transit using cryptographic signatures.
  • DMARC (25 points): Tells receivers what to do with unauthorized emails and provides reporting. A monitoring-only policy (none) earns partial credit; enforcing policies (quarantine/reject) earn full points.
  • MX Records (15 points): Confirms your domain is properly configured to receive email.
  • Blacklist Status (20 points): Checks major domain-based blacklists for any listings.

Frequently Asked Questions

What is email deliverability?

Email deliverability is the ability of your emails to reach recipients' inboxes rather than landing in spam folders or being rejected. It depends on your domain reputation, authentication setup (SPF, DKIM, DMARC), sending practices, and content quality.

How do I check if my emails are going to spam?

Start by checking your email authentication with this tool. Missing SPF, DKIM, or DMARC records are the most common causes of spam placement. Also monitor your sender reputation through Google Postmaster Tools and check if you are on any blacklists.

What is a good email deliverability score?

An A grade (90-100 points) means your authentication is properly configured. This requires SPF, DKIM, and DMARC records in place, with DMARC set to quarantine or reject, and no blacklist presence. Most legitimate senders should aim for at least a B grade (75-89).

Why are my emails going to the spam folder?

Common causes include missing authentication records (SPF, DKIM, DMARC), high bounce rates, spam complaints from recipients, being on a blacklist, spam trigger words in content, or sending to purchased lists. Fix authentication first — it is the most impactful change.

How do I improve my email deliverability?

Start with the fundamentals: set up SPF, DKIM, and DMARC records (use our free generators). Then maintain list hygiene by removing inactive subscribers, keep complaint rates below 0.3%, warm up new domains gradually, and send relevant, expected content.
