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.
