# 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.

<div align="left"><figure><img src="/files/I7SDXSR2Kxc3cOVXirLH" alt=""><figcaption></figcaption></figure></div>

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]]

<div align="left"><figure><img src="/files/IsTYYaGtSAzyqvsugtbO" alt=""><figcaption></figcaption></figure></div>

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. &#x20;

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.

<div align="left"><figure><img src="/files/7qkoGuGhWQ1VuLkKr9XI" alt=""><figcaption></figcaption></figure></div>

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