# Pardot emails are missing a required Unsubscribe or Preference Center tag Pardot requires that all emails have a valid Unsubscribe or Preference Center Link token in both the HTML and TEXT versions of the email. Follow this article to ensure your email compiles. ### Verify tags in HTML version * In FeedOtter, navigate to the Edit view of your Issue or Campaign. * Click on **Customize** from the left side tab bar. * Click on the **Code** tab.

By default this will display the HTML email code. Above the code box there is search interface. Use this to search for the following texts: * unsubscribe * emailpreference * \[\[feedotter.unsubscribe\_link]]

If the \[\[feedotter.unsubscribe\_link]] is present your HTML code is compliant and you can move on to checking the Text version. When you search for the other variants, you MUST have something like this {{Unsubscribe}} or {{EmailPreferenceCenter}}. These are the Pardot specific tokens that are required. If none of these values are present in your email you will need to add them to your email before it can be published to Pardot. ### Verify tags in TEXT version Same process as above except we change the code view to the TEXT code view.

Ensuring one of the supported tags is present will allow your email to be published.
