Pass DMARC before your email
starts bouncing.
Google, Yahoo and Microsoft now reject or junk mail from domains without a DMARC policy. Blankitt shows you every service sending as you, fixes SPF/DKIM, and gets you to safe enforcement — UK-built, UK-supported, no enterprise contract.
Sending to Gmail or Outlook? A missing or misconfigured DMARC record means your mail lands in spam — or bounces.
Free domain check — no account required. UK public sector: NCSC Mail Check retires 31 March 2026, so you'll need a replacement.

Understand email authentication
New to DMARC? Learn the fundamentals of email authentication and why it matters.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that protects your domain from being used in phishing attacks.
Learn moreSPF Explained
SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of your domain using DNS TXT records.
Learn moreDKIM Explained
DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, allowing recipients to verify they haven't been altered in transit.
Learn moreBuilt and run by the UK team behind the Blankitt platform. UK-built and UK-supported.
