What is Email Authentication?
SPF
Sender Policy Framework — defines which servers are authorized to send emails on behalf of your domain.
DKIM
DomainKeys Identified Mail — adds a digital signature to verify your emails haven't been tampered with.
DMARC
Domain-based Message Authentication — tells receiving servers what to do when SPF or DKIM fails. The last line of defense.
How We Help
Check
We analyze your domain's DNS records to identify misconfigurations, missing DMARC policies, and vulnerabilities.
Fix
Our experts implement the correct SPF, DKIM, and DMARC configurations for all your email platforms.
Monitor
Continuous automated monitoring with specialist review ensures your compliance is maintained over time.
Why Does This Matter?
Without proper email authentication, your domain is an open door for attackers.
Domain Spoofing
Without DMARC, hackers can send emails pretending to be you — phishing your clients, partners, and employees.
Email Deliverability
Gmail, Microsoft, and Yahoo now require proper authentication. Without it, your emails land in spam or get rejected.
Industry Compliance
Google and Yahoo enforce strict DMARC requirements since 2024. Microsoft joined in 2025. Non-compliance means rejected emails.
Brand Protection
A single spoofing incident can damage years of brand trust. DMARC prevents unauthorized use of your domain name.
Email Source Map
NewFinds what's broken, and shows you how to fix it.
Send one test email from each tool you use to send mail — invoicing, CRM, marketing, helpdesk. For every one that fails SPF, DKIM or DMARC, an AI-guided assistant walks you through exactly what to fix, matched to your own DNS host and sending tool.
See who is being spoofed right now
We publish a live map of where spoofed email is coming from. Most of it uses the name of a real company whose domain has weak or missing DMARC — which is exactly what this site helps you fix.
