Free Email Deliverability Score

Get an instant score out of 100 for any domain's email setup. See what's broken and how to fix it.

What Your Email Deliverability Score Means

Email providers like Gmail, Yahoo, and Outlook evaluate your domain's DNS configuration before deciding whether to deliver your email to the inbox, spam folder, or reject it entirely. Our deliverability score gives you a single number out of 100 that reflects how trustworthy your domain appears to receiving mail servers.

What We Check

📬 MX Records (Mail Exchange)

MX records tell the world where to deliver email for your domain. Without them, you cannot receive any mail at all. We verify your MX records exist, show their priority order, and ensure they point to reachable servers.

🛡️ SPF (Sender Policy Framework)

SPF is a TXT record that lists which mail servers are authorized to send email from your domain. Gmail and Outlook check this to prevent email spoofing. Missing SPF means anyone can impersonate your domain. SPF setup guide →

📋 DMARC (Domain-based Message Authentication)

DMARC builds on SPF and DKIM to tell receivers what to do when authentication fails (quarantine, reject, or report only). Gmail and Yahoo now require DMARC for anyone sending bulk email (5,000+ per day). DMARC setup guide →

🔐 DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to every email you send, proving it wasn't altered in transit. Think of it as a tamper-proof seal. Most email providers (Google Workspace, Microsoft 365, Proton) support DKIM out of the box. DKIM setup guide →

🚫 DNS Blacklist Status

We check your mail server IPs against 5 major DNS blacklists: Spamhaus ZEN, SpamCop, Barracuda, SORBS, and PSBL. Each blacklisted IP costs you 15 points. We show exactly which lists flagged you and provide delisting instructions.

FAQ

Q: Is the deliverability score really free?
Yes. Unlimited domain checks, no signup, no credit card required. We query DNS in real-time.
Q: What's a good score?
80-100 is excellent (your emails will land in inboxes). 60-79 is decent with room for improvement. Below 60 means your emails are likely being flagged as spam or rejected.
Q: How long do DNS fixes take to affect my score?
DNS changes propagate within minutes to a few hours. Run the check again after making changes to see your updated score.
Q: My score is 100 but emails still go to spam. Why?
DNS configuration is one factor. Email content, sending reputation, open rates, and engagement also matter. Try our Spam Score Checker for content analysis.
