Frequently Asked Questions
What is DKIM?
DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.
What is a DKIM selector?
A selector is a string used to point to a specific DKIM public key record in your DNS. You can have multiple selectors for different mail streams.
How do I find my selector?
Your email service provider (like Google, Office 365, or Mailchimp) will provide you with the selector name when you set up DKIM.
