The following sections describe how to set up your domain for these uses within Barracuda PhishLine:

For related information, refer to Using Your Own Email Account for Training Invitations and Choosing How to Send Training Invitations.

Using Your Own Domain for Both Landing Pages and Sending Emails

To use your own registered domain exclusively with Barracuda PhishLine for use as both:                 

  • a landing page domain, and 
  • the from address for sending campaign emails:
  1. Point your nameservers to:
      If you are not able to specify all seven nameservers, enter at least one Dynect name server and one dnsmadeeasy nameserver.
  2. Contact Barracuda PhishLine Support and provide the following information:
    • your domain name(s) you want to use
    • Barracuda PhishLine instance(s) that require the domains
    • email accounts (for example,
  3. Barracuda PhishLine Support will set up DNS for the domain(s) and create the associated web and email account servers.  This process usually takes 1-2 days.

You do not lose control of your domain. You can always choose to point the nameservers elsewhere. At that point, the landing page and email servers will no longer point to Barracuda PhishLine. As a courtesy, please let us know when we can remove the domain from your instance.

Using a subdomain of your organization's actual domain provides the best context. Alternatively, with your permission, Barracuda can register another domain to use as the Customer Awareness Domain. For example, Barracuda can register and set up DNS for .

To set up a Customer Awareness Domain for links within campaign emails:

In this example, the domain for your organization is  and the subdomain is securityawareness.

  1. Request that your  DNS  Administrator  add  a  subdomain,  such  as  securityawareness, with  a  CNAME  that  points  to Set the TTL to 60 seconds or something small to allow Barracuda PhishLine to redirect to other data centers without lag. To test, ping and check that it resolves to
  2. Navigate to System > Global Settings. Under Advanced Domain, set the Customer Awareness Domain to your  subdomain, in this case, Click Save.
  3. Send a test email to yourself to confirm that outbound email campaigns with training links use
