Duplicate sender authentication CNAME records on GoDaddy domains

When users add CNAME records on a GoDaddy hosted website, they are getting tagged with your domain twice.

For example, if you post a record like this:

em1234.domain.com

It gets posted like this:

em1234.domain.com.domain.com

To resolve this issue, please remove all SendGrid posted records from your side. Once these records are removed, please re-add them using the following formatting:

Notice: If you have multiple Domain Authentication entries, please make sure to remove all the ones that are not valid.
