Set User Information and Attributes in Collect Tracking Code

The setUserInfo push passes the Contact ID. Regardless of the type of ID chosen, use the email label for this field and add the value in the SetUserInfo snippet. You don’t need to add it to every page because adding it once ties the known identifier to the Collect Tracking Code cookie.

Tip Configure Collect Tracking Code to store subscriber information when a contact enters an email address on the website or clicks through a marketing email. To use the Personalization Builder Integrations, you must use the user’s email address. For privacy reasons, avoid using a personally identifiable information (PII) identifier or hashing the email.

Set User Info

<script type="text/javascript">       
    _etmc.push(["setOrgId", "MID"]);
    _etmc.push(["setUserInfo", {
        "email": "INSERT_EMAIL_OR_UNIQUE_ID"
    }]);
    _etmc.push(["trackPageView"]);
</script>

Tip Add this call everywhere that a user logs in or becomes known, such as login pages and sign-up pages.
