I was wondering if using tabcmd is the only way? If so, how does Tableau send out the email? We have no email service installed on our server. I see a reference to something call the "email alert center". What is this?
Tabcmd does not actually provide the functionality to "send" emails, it can hook into an existing email generation, to send the email. The "email alert center" is just a reference to the code that would be used to send the email to the 3rd party product.
