Evalanche (by SC-Networks) is a German B2B marketing automation platform serving mid-market and enterprise DACH customers with lead scoring, nurture programs, and CRM integration. The unsubscribe mechanism uses the [[UNSUBSCRIBE_URL]] merge tag in email templates, and Evalanche emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with double opt-in enforcement by default, matching German UWG regulatory expectations. Data residency in Germany matches DACH data localization requirements. This guide covers the tag, the DACH regulatory model, and how to verify the setup end to end.
Evalanche unsubscribe link
| Tag syntax | [[UNSUBSCRIBE_URL]] |
| Placement | Auto-embedded in default template footer |
| Scope | Contact-level opt-out with double opt-in default |
| Config path | Administration > Client settings > Email footer |
| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Evalanche
Place the merge tag exactly as shown below in the email template. Evalanche replaces it at send time with a signed URL scoped to the recipient and campaign.
[[UNSUBSCRIBE_URL]]For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="[[UNSUBSCRIBE_URL]]">Unsubscribe from this list</a>Auto-embedded in default template 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.
Evalanche enforces double opt-in by default matching German UWG and Austrian TKG requirements. Legacy accounts migrated from other ESPs with single opt-in contacts must run a re-permission campaign before sends can go out. Imported contacts without documented double opt-in are quarantined until confirmed. Analogous to Maileon and BACKclick DACH compliance patterns.
Testing your Evalanche unsubscribe link
- Send a test message to a controlled Gmail address you own via the Evalanche 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 Evalanche unsubscribe link (step by step)
Evalanche default templates include the unsubscribe link in the footer, but custom HTML templates require the tag inserted manually.
- Open your campaign or template in the Evalanche editor.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the merge tag
[[UNSUBSCRIBE_URL]]. Evalanche replaces it at send time with a signed URL scoped to the contact. - Wrap it in an anchor:
<a href="[[UNSUBSCRIBE_URL]]">Abmelden</a>for German,Unsubscribefor English. - Configure the sending domain under Administration > Client settings > Email footer.
- Send a test to a seed address and verify the rendered link routes to the Evalanche-hosted preference page.
German UWG double opt-in enforcement
Evalanche enforces double opt-in by default matching German UWG (Gesetz gegen den unlauteren Wettbewerb) and Austrian TKG requirements. Legacy accounts migrated from other ESPs with single opt-in contacts must run a re-permission campaign before sends can go out. Imported contacts without documented double opt-in are quarantined until confirmed. This is analogous to Maileon and BACKclick DACH compliance patterns and is stricter than US CAN-SPAM but expected in the German market where email marketing is heavily regulated.
RFC 8058 one-click headers
Evalanche 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 Administration > Client settings. SPF and DKIM records must be verified. German data residency defaults align with DACH data localization requirements, an important differentiator for German government agency and BaFin-regulated financial services customers.
B2B lead scoring and nurture program enforcement
Evalanche B2B lead scoring and multi-step nurture programs respect the contact opt-out flag at every send step. A contact who unsubscribes mid-nurture exits the program automatically and can be routed to alternative paths (sales rep manual outreach, cross-sell recommendation). CRM sync with Salesforce, HubSpot CRM, and Microsoft Dynamics writes opt-out state back to the CRM contact record automatically. This bidirectional sync is essential for B2B enterprises running unified sales and marketing motions.
