Refresh alert mail will go based on the mail id mentioned in server configuration. please try some group mail there and get it.
I am not tried yet but check and let us know.
Thank you, Sankar
Currently the owner of the dashboard gets the email but I would like to know if there is a way to include a Distribution list when a refresh extract fails.
Let me know if you need further explanation.
As mentioned by Sankar, you have to specify the email ID of a distribution list in the configuration. Tableau server will send email to the DL and mail server will automatically distribute the email to specified users under the DL.
