Email Authentication
Verification methods ensuring sender credibility.
Email authentication protocols like SPF, DKIM, and DMARC confirm that emails are genuinely sent from the claimed domain, preventing spoofing and phishing attacks. These protocols help ISPs determine whether to trust an email, impacting deliverability. Authentication improves the chances of emails landing in the inbox rather than being flagged as spam. Businesses that prioritize authentication demonstrate accountability and protect their sender reputation while ensuring secure and trustworthy communication.
