In the email notice about Roku OS8, you have a link to "t.myvisualiq.net’s server DNS address could not be found." Microsoft says these links are for tracking clicks from the email. If the tracking fails because the server can't be found, then the link doesn't work to the information. Would you (Roku) consider adding alternate links in the email in case this problem persists? Otherwise the information is useless to me.

That redirects to t.myvisualiq.com and then it dies.
