Pardot (rebranded to Salesforce Marketing Cloud Account Engagement in 2022) is a B2B marketing automation platform natively integrated with Salesforce CRM, serving mid-market and enterprise B2B customers with lead scoring, nurture programs, and Salesforce Campaign attribution. The unsubscribe mechanism uses the %%unsubscribe%% merge tag auto-injected into every campaign footer, and Pardot emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the prospect level with native Salesforce Lead/Contact sync. This guide covers the tag, the Salesforce-native architecture, and how to verify the setup end to end.
Pardot (Salesforce) unsubscribe link
| Tag syntax | %%unsubscribe%% |
| Placement | Auto-embedded in every campaign footer |
| Scope | Prospect-level opt-out with Salesforce Lead/Contact sync |
| Config path | Admin > Email > List email settings |
| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Pardot (Salesforce)
Place the merge tag exactly as shown below in the email template. Pardot (Salesforce) replaces it at send time with a signed URL scoped to the recipient and campaign.
%%unsubscribe%%For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="%%unsubscribe%%">Unsubscribe from this list</a>Auto-embedded in every campaign footer
Yes, automatic for authenticated sending domains The recipient's mailbox provider (Gmail, Yahoo) uses the List-Unsubscribe-Post header to expose the native one-click button on the message. Requires domain authentication with DKIM and DMARC.
Pardot rebranded to Salesforce Marketing Cloud Account Engagement in 2022, but the Pardot product name persists in admin URLs and documentation. Salesforce Lead/Contact Email Opt Out field is the single source of truth: a Salesforce-side opt-out flows to Pardot automatically, but the sync direction and field mapping must be configured explicitly. Business Unit isolation in enterprise Pardot accounts means per-BU suppression, not global.

How to add the Pardot unsubscribe link (step by step)
Pardot email templates include the unsubscribe link in the required List Email footer, but custom HTML templates require the tag inserted manually.
- Open your list email or template in Pardot Marketing > Emails > Templates.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the merge tag
%%unsubscribe%%. Pardot replaces it at send time with a signed URL scoped to the prospect. - Wrap it in an anchor:
<a href="%%unsubscribe%%">Unsubscribe</a>. - Configure the sender identity under Admin > Email > List email settings.
- Send a test to a seed address and verify the rendered link routes to the Pardot-hosted preference page and updates the Salesforce Lead/Contact Email Opt Out field.
Pardot to Account Engagement rebrand and Salesforce sync
Pardot rebranded to Salesforce Marketing Cloud Account Engagement in 2022, but the Pardot product name persists in admin URLs and documentation. Salesforce Lead/Contact Email Opt Out field is the single source of truth: a Salesforce-side opt-out flows to Pardot automatically, but the sync direction and field mapping must be configured explicitly. Business Unit isolation in enterprise Pardot accounts means per-BU suppression, not global. Configure BU-level consent scoping carefully in multi-BU deployments to match regulatory expectations across business units.
RFC 8058 one-click headers
Pardot added RFC 8058 one-click unsubscribe automatically ahead of the Google and Yahoo February 2024 requirements. The List-Unsubscribe and List-Unsubscribe-Post headers inject on every list email send from domains authenticated under Admin > Domain Management. SPF and DKIM records must be verified per BU in enterprise deployments. One-click unsubscribe updates the Salesforce Email Opt Out field automatically via the native sync, keeping the CRM contact record accurate.
Lead scoring, nurture programs, and Engagement Studio
Pardot lead scoring, nurture programs, and Engagement Studio workflows respect the prospect Email Opt Out flag at every send step. A prospect who unsubscribes exits all workflows automatically and can be routed to alternative paths (sales rep manual outreach in Salesforce, ABM ad targeting). Engagement Studio branching logic can be configured to detect opt-out events and trigger downstream actions like Salesforce task creation for sales follow-up on high-value prospects who unsubscribed from marketing.
