Whenever I paste in the following code to add an unsubscribe link, it doesn't appear in the footer of the test email.
<p><span style="font-family: Verdana; font-size: xx-small;">If you no longer wish to receive these emails, click on the following link: <a href="%mkt_opt_out_prefix%UnsubscribePage.html?mkt_unsubscribe=1&mkt_tok=##MKT_TOK##">Unsubscribe</a></span></p>
This is what I took from your tutorial and it's not showing up for some reason. It looks fine in the editor preview, but when I send myself a test, it's not there in the footer. I have approved the email, so I'm not sure what's going on. Please help!
