DMARC
Definition
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that builds on SPF and DKIM to protect domains from email spoofing, phishing, and other unauthorized use.

Email Deliverability
Email deliverability is the ability of an email to successfully reach a recipient's primary inbox, rather than being blocked or routed to spam folders. It is crucial for B2B sales as it directly impacts the effectiveness of outreach and communication.
SPF Record
An SPF (Sender Policy Framework) record is a type of DNS TXT record that specifies which mail servers are authorized to send email on behalf of a domain. It helps prevent email spoofing and enhances email deliverability by allowing recipient servers to verify the sender's legitimacy.
DKIM
DKIM (DomainKeys Identified Mail) is an email authentication protocol that adds a digital signature to outgoing emails, allowing recipient servers to verify that the email was sent from an authorized server and has not been tampered with in transit. This helps prevent email spoofing and phishing by ensuring the sender's domain authenticity.
