How long will it take to get my domain set up in Tatango?

CNAME record changes can take up to 72 hours to go into effect, but typically they happen much sooner - in just a few minutes.

What should I do if my verification fails?

Verify if the CNAME records are correctly created within your domain registrar. If the problem persists, get in touch with Tatango's customer service.

We will fallback to as the domain for tracking links should you choose to continue.

Where can I make changes to your DNS record?

Wherever you have registered or currently manage your domain names, you can update your DNS records. Not all domain registration services, however, allow you to edit all DNS records. If you are unable to update the records listed above, contact your DNS provider for assistance.

The process of adding records to your DNS is determined by the domain provider you use. The following are links to documentation for commonly used providers:
