I just created an email and added the {{my.Save the Date}} token. The token has the HTML statement below in the Hyperlink Text field of the Edit Calendar File dialog box of the Save the Date My Token.
<img src="http://ww2.conductor.com/rs/conductor2/images/Add%2520Button.png" alt="Add to Calendar" />
In the sent email, the button displays beautifully and the link is decorated with the Marketo tracking code, but when I click the button a web page is opened at the URL (http://na-f.marketo.com/rs/conductor2/60/Conductor) with a 404 error and no ICS file is downloaded. The URL looks incomplete. I also tried this with "Save the Date" in the Hypertext Link field, and the link still displays a web page with a 404 error.
Any idea what is causing this?
