ActiveCampaign is one of the leading SMB and mid-market marketing automation platforms combining email marketing, CRM, and workflow automation for e-commerce, SaaS, and services businesses. The unsubscribe mechanism uses the %UNSUBSCRIBELINK% merge tag auto-injected into every campaign footer, and ActiveCampaign emits RFC 8058 headers automatically for authenticated domains. Consent is tracked at the contact level with per-list opt-out and account-wide unsubscribe flag options. This guide covers the tag, the automation-first model, and how to verify the setup end to end.
ActiveCampaign unsubscribe link
| Tag syntax | %UNSUBSCRIBELINK% |
| Placement | Auto-embedded in every campaign footer, enforced at send |
| Scope | Contact-level opt-out with per-list granularity |
| Config path | Settings > Advanced > Unsubscribe link |
| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in ActiveCampaign
Place the merge tag exactly as shown below in the email template. ActiveCampaign replaces it at send time with a signed URL scoped to the recipient and campaign.
%UNSUBSCRIBELINK%For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="%UNSUBSCRIBELINK%">Unsubscribe from this list</a>Auto-embedded in every campaign footer, enforced at send
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.
ActiveCampaign automation workflows respect the contact-level unsubscribe flag at every send step, but if a contact enters a workflow mid-flight and unsubscribes, they are exited at the next send step, not immediately. This creates a small window where a workflow-triggered send might reach a just-unsubscribed contact. For high-value transactional workflows (post-purchase, receipts), configure the transactional stream to bypass the marketing unsubscribe flag legally.
Testing your ActiveCampaign unsubscribe link
- Send a test message to a controlled Gmail address you own via the ActiveCampaign campaign preview action
- Click the footer unsubscribe link and confirm the opt-out on the landing page
- Check the subscriber or contact record: the status should be Unsubscribed within seconds
- Verify the RFC 8058 headers in Gmail: open the message, click three dots, then Show original. Look for
List-UnsubscribeandList-Unsubscribe-Post: List-Unsubscribe=One-Click

How to add the ActiveCampaign unsubscribe link (step by step)
ActiveCampaign templates include the unsubscribe link in the default footer and enforce its presence at send time; custom HTML templates missing the tag are rejected at pre-flight validation.
- Open your campaign or automation email in the ActiveCampaign editor.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the merge tag
%UNSUBSCRIBELINK%. ActiveCampaign replaces it at send time with a signed URL scoped to the contact. - Wrap it in an anchor with your preferred label:
<a href="%UNSUBSCRIBELINK%">Unsubscribe</a>. - Add the physical postal address. ActiveCampaign reads it from Settings > Advanced > Compliance settings.
- Send a test to a seed address and verify the rendered link routes to the ActiveCampaign-hosted preference page.
Contact-level opt-out and per-list granularity
ActiveCampaign tracks unsubscribes at the contact level with per-list granularity. A contact who opts out of List A stays subscribed to List B by default; the account-wide unsubscribe flag applies globally and blocks all future sends. Custom preference centers can expose per-list toggles or per-tag topic preferences, giving subscribers granular opt-out control. This is more flexible than Mailchimp Audience Groups (which requires single-audience architecture) but similar to Klaviyo List and Segment scope.
RFC 8058 one-click headers
ActiveCampaign 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 marketing send from domains authenticated under Settings > Advanced > Email deliverability. SPF and DKIM records must be verified. Transactional-classified sends (defined by the account transactional sending flag) can bypass RFC 8058 headers when configured as pure transactional streams.
Automation workflows and unsubscribe timing
ActiveCampaign automation workflows respect the contact-level unsubscribe flag at every send step, but if a contact enters a workflow mid-flight and unsubscribes, they are exited at the next send step, not immediately. This creates a small window where a workflow-triggered send might reach a just-unsubscribed contact. For high-value transactional workflows (post-purchase, receipts), configure the transactional stream to bypass the marketing unsubscribe flag legally. Automation goals and conditional splits can also check the subscription status to route exited contacts to alternative paths (win-back campaigns, feedback surveys).
Frequently Asked Questions
What is the ActiveCampaign unsubscribe tag?
The tag is %UNSUBSCRIBELINK%. ActiveCampaign replaces it at send time with a signed URL scoped to the contact. Use it inside an anchor: <a href="%UNSUBSCRIBELINK%">Unsubscribe</a>.
Can subscribers opt out of one ActiveCampaign list without leaving all lists?
Yes. ActiveCampaign default opt-out applies per list. The account-wide unsubscribe flag is available via preference center for full removal control. Custom preference centers can expose per-tag topic toggles for granular subscription management.
Does ActiveCampaign support one-click unsubscribe for Gmail and Yahoo?
Yes, automatically for authenticated domains. ActiveCampaign injects List-Unsubscribe and List-Unsubscribe-Post headers on every marketing send from domains verified under Settings > Advanced > Email deliverability.
Do automation workflows honor mid-flight unsubscribes?
Yes at the next send step, not immediately. A contact who unsubscribes mid-workflow is exited at the next email step, potentially creating a small window where a workflow-triggered send reaches a just-unsubscribed contact. Configure automation goals to check subscription status for tighter enforcement.
Can I resubscribe a contact who unsubscribed from ActiveCampaign?
Not through the API without explicit consent capture. ActiveCampaign enforces permanent suppression on opt-outs. Reactivation requires the contact to re-opt in through an ActiveCampaign signup form or documented consent update.
