FAQ: Why isn’t my Custom Domain working?

To run high-volume campaigns, it is highly recommended that you set up and use a custom tracking domain in Voluum. While doing so, you need to set a CNAME record for your custom subdomain pointing to your unique Voluum Dedicated Domain.

Following the CNAME configuration for your subdomain and after adding your custom domain to your Voluum account, it's possible that you will be returned with the following response after verifying the domain's DNS settings:

  • If you have set up a new domain make sure to wait 2-20 hours to fully propagate Domain Name System (DNS).

  • If you are setting a CNAME record on an older domain, keep an eye out for the Time to Live (TTL) setting; by default, the TTL setting is set to 14400 seconds which is 4 hours. It means that your subdomain and CNAME may take that long to propagate. You can shorten this by modifying the TTL number for your CNAME record.
