Misconfigured email gets blocked by corporate filters. We check your SPF, DKIM, and DMARC to show you what's broken—and how to fix it.
The Enuclea Email Maturity Score weighs five configuration factors, plus a blacklist check. A score of 70+ indicates solid deliverability. Below 40 means critical issues.
We check your mail server IP against 5 major blacklists. Being listed results in a score deduction up to -30 points.
Sender Policy Framework (SPF) is a DNS record that lists which servers are authorized to send email for your domain. Without SPF, anyone can send email pretending to be you. Gmail and Outlook check SPF on every incoming message—if it fails, your email goes to spam or gets rejected.
DomainKeys Identified Mail (DKIM) adds a cryptographic signature to your emails. The receiving server verifies this signature against a public key in your DNS. DKIM proves your email wasn't tampered with in transit and came from an authorized sender.
Domain-based Message Authentication, Reporting & Conformance (DMARC) tells receiving servers what to do when SPF or DKIM fails. A DMARC policy of "reject" means unauthenticated emails are blocked entirely. Without DMARC, spammers can spoof your domain freely.
Free email (@gmail, @yahoo) shares infrastructure with millions of users—including spammers. Corporate security filters flag these as higher risk. A custom domain gives you a dedicated sending reputation and allows proper SPF/DKIM/DMARC configuration.
Reverse DNS maps an IP address back to a hostname. Email servers check that your sending IP's PTR record matches your domain. Mismatched or missing PTR records signal "possibly spam" to receiving servers—especially Gmail's filters.
When your emails land in spam, clients don't see your invoices. Proposals go unread. Follow-ups vanish. The fix isn't sending more emails—it's configuring your domain's DNS records correctly so you pass authentication checks.
