Didn't recieved Digicert e-mail about activating certificate for my custom domain

Question

Hello, I am trying to implement a certificate on my CDN using "CDN-managed certificate" by following this tutorial:

https://learn.microsoft.com/pt-br/azure/cdn/cdn-custom-ssl?tabs=option-1-default-enable-https-with-a-cdn-managed-certificate&WT.mc_id=Portal-Microsoft_Azure_Support#custom-domain-isnt-mapped-to-your-cdn-endpoint

According to it:

"If the CNAME record entry contains the cdnverify subdomain, follow the rest of the instructions in this step.

DigiCert sends a verification email to the following email addresses. Verify that you can approve directly from one of the following addresses:

admin@your-domain-name.com
administrator@your-domain-name.com
webmaster@your-domain-name.com
hostmaster@your-domain-name.com
postmaster@your-domain-name.com"

I was supposed to receive an e-mail from digicert about the implementation of the certification on my custom domain. I've checked it on my DNS zones and I have a CNAME with the value of my endpoint and the subdomain "cdnverify". However I've checked mine and the admin (assuming its the account subscription) e-mail accounts and didn't received any e-mails. How can I proceed?

Thank you for your time.
