Add a layer of security to your emails with SPF or DKIM

Protect your emails from phishing scams, malware and other attacks by using a Sender Policy Framework (SPF) and a DomainKeys Identified Mail (DKIM) system. In essence, SPF allows you to define exactly which IP addresses are allowed to send mail from a specific domain. If a bad actor attempts to spoof an email from a legitimate source, the SPF can flag the email because it didn’t originate from the correct domain. On the other hand, DKIM uses an encryption key and digital signature to verify an email’s authenticity.
