The reason we can’t take action in this case is that the Certificate Authority (CA) needs explicit approval from a person who has Admin access to the domain before they issue the SSL Certificate. Domain Control Validation (DCV) is mandatory for all SSLs.
Only you or an authorized person in your company will have access to the email address supplied when registering the domain, or email forwarding for any one of the generic @example.com email addresses.
This is a security measure for DCV. Email addresses not associated with your domain are not permitted by the Certificate Authority.
You can use Sectigo’s SSL Validation Tool to resend the approval email if you haven’t received it, or specify another email address linked to your domain.
