  Verifies an email identity for use with Amazon Pinpoint. In Amazon Pinpoint, an identity is an email address or
  domain that you use when you send email. Before you can use an identity to send email with Amazon Pinpoint, you
  first have to verify it. By verifying an address, you demonstrate that you're the owner of the address, and that
  you've given Amazon Pinpoint permission to send email from the address.
  </p>
  <p>
  When you verify an email address, Amazon Pinpoint sends an email to the address. Your email address is verified
  as soon as you follow the link in the verification email.
  </p>
  <p>
  When you verify a domain, this operation provides a set of DKIM tokens, which you can convert into CNAME tokens.
  You add these CNAME tokens to the DNS configuration for your domain. Your domain is verified when Amazon Pinpoint
  detects these records in the DNS configuration for your domain. It usually takes around 72 hours to complete the
  domain verification process.
