# Email CNAME Records

If you don't have access to modify your companies DNS records, you can email the records to a co-worker who does to complete [Domain Authentication](/docs/sendgrid/ui/account-and-settings/how-to-set-up-domain-authentication) and/or [Link Branding](/docs/sendgrid/ui/account-and-settings/how-to-set-up-link-branding) setups. This email includes a direct link to the DNS records. The link does expire, but the recipient doesn't need login access to your Twilio SendGrid account.
