Ternair is a Dutch B2B marketing automation and customer data platform serving Northern European enterprise customers with omnichannel campaign orchestration, CDP-based segmentation, and account-based marketing. The unsubscribe mechanism uses the ${unsubscribe_url} merge variable in email templates, and Ternair emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the customer profile level in the integrated CDP. This guide covers the tag, the CDP-first architecture, and how to verify the setup end to end.

| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Ternair Software
Place the merge tag exactly as shown below in the email template. Ternair Software 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.
Ternair customer data platform unifies consent across email, mobile, and web channels. An email opt-out flows to the CDP profile and can trigger cross-channel enforcement if configured. Enterprise customers running distinct product programs should carefully configure per-program consent scoping in the CDP to avoid global opt-out enforcement that surprises B2B marketers used to per-program opt-out patterns.
Testing your Ternair Software unsubscribe link
- Send a test message to a controlled Gmail address you own via the Ternair Software 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

${unsubscribe_url}. Ternair replaces it at send time with a signed URL scoped to the CDP customer profile. - Wrap it in an anchor:

CDP profile-level opt-out and cross-channel enforcement
Ternair customer data platform unifies consent across email, mobile, and web channels. An email opt-out flows to the CDP profile and can trigger cross-channel enforcement if configured. Enterprise customers running distinct product programs should carefully configure per-program consent scoping in the CDP to avoid global opt-out enforcement that surprises B2B marketers used to per-program opt-out patterns. Configure per-brand or per-program consent scopes during CDP setup to preserve granular opt-out control.
RFC 8058 one-click headers
Ternair 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 Configuration > Email > Sender settings. SPF and DKIM records must be verified. Dutch and Northern European data residency defaults align with GDPR expectations for BeNeLux and DACH enterprise customers.
Account-based marketing and B2B segmentation
Ternair account-based marketing capabilities segment prospects by company account rather than individual contact, letting B2B marketers coordinate multi-touch outreach across a target account s decision committee. Opt-out events at the individual contact level do not automatically suppress the entire account, letting other decision-makers continue receiving relevant content. This account-level granularity is essential for enterprise B2B where a single deal spans 5-20 buying committee members with different content preferences.
