The Domain Keys Identified Mail (DKIM) functionality provides an email authentication method to help ensure that a message is not modified while it is in transit and the receiver will still know that the email is coming from you. DKIM is compatible with current email structures and works with SPF and DMARC to maintain multiple layers of security for domains sending emails.
Emails with DKIM set up appear more legitimate to its recipients and reduces the chance of your email going to Junk or Spam. Malicious spam and phishing campaigns use spoofing emails from trusted domains, setting up your DKIM makes it harder to spoof email from domains that use it.
In addition, setting up your DKIM helps build a reputation on your domain over time. The more emails you send using best email and delivery practices builds a good sending reputation with ISPs, which in turn helps with email deliverability.
