If you've tried setting up an Email Sending Domain in Insightly Marketing, you may have come across a few unfamiliar terms: DKIM and SPF.
SPF stands for Sender Policy Framework.
DKIM stands for DomainKeys Identified Mail.
They are email authentication protocols that help ensure that the mail you send is verifiable and that it stays out of SPAM boxes. Authentication allows the owner of a domain to specify which mail servers are allowed to send emails from the domain.
So if you were setting up an Email Sending Domain in Insightly Marketing and used SPF verification, you'd be telling your domain that Insightly Marketing is allowed to send emails on your behalf through the domain.
SPF uses path-based authentication while DKIM uses an identity-based authentication.
How do I use them?
In order to start sending Emails through Insightly Marketing, you must verify your domain name at your SMTP relay service provider.
Some examples of this type of provider are SendGrid, Mandrill, Amazon SES, and MailGun. Whichever provider you are using will have documentation to walk you through the verification process.
Consult your domain administrator if you want to setup SPF or DKIM authentication.
