AdMail.net is an email marketing platform serving Canadian small businesses and nonprofits with CASL compliance defaults, integrated postal mail campaign options, and Canadian-hosted infrastructure. The unsubscribe mechanism uses the *|UNSUB|* merge tag auto-injected into every campaign footer, and AdMail.net emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the list level with CASL express/implied consent classification. This guide covers the tag, the CASL enforcement model, and how to verify the setup end to end.
Admail.net unsubscribe link
| Tag syntax | *|UNSUB|* |
| Placement | Auto-embedded in every campaign footer |
| Scope | Per-list opt-out with CASL classification |
| Config path | Account > Sender identity > Footer template |
| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Admail.net
Place the merge tag exactly as shown below in the email template. Admail.net replaces it at send time with a signed URL scoped to the recipient and campaign.
*|UNSUB|*For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="*|UNSUB|*">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.
AdMail.net CASL express/implied consent classification enforces the 2-year implied consent expiration timer under Canadian law. Contacts approaching expiration should be converted to express consent via a re-permission campaign before the deadline, or AdMail.net suppresses further sends automatically. The integrated postal mail campaign option requires separate consent tracking for postal addresses versus email addresses under CASL and PIPEDA.
Testing your Admail.net unsubscribe link
- Send a test message to a controlled Gmail address you own via the Admail.net 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 AdMail.net unsubscribe link (step by step)
AdMail.net 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 AdMail.net editor.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the merge tag
*|UNSUB|*. AdMail.net replaces it at send time with a signed URL scoped to the subscriber. - Wrap it in an anchor:
<a href="*|UNSUB|*">Unsubscribe</a>. - Configure the sender identity under Account > Sender identity.
- Send a test to a seed address and verify the rendered link routes to the AdMail.net-hosted preference page.
CASL express and implied consent classification
AdMail.net CASL express/implied consent classification enforces the 2-year implied consent expiration timer under Canadian law. Contacts approaching expiration should be converted to express consent via a re-permission campaign before the deadline, or AdMail.net suppresses further sends automatically. Analogous to Envoke Canadian regulatory-first patterns. CASL fines can reach CAD 10 million per violation for corporate senders, making platform-level enforcement essential for Canadian nonprofits and small businesses.
RFC 8058 one-click headers
AdMail.net 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 Account > Sender identity. SPF and DKIM records must be verified. Canadian data residency defaults align with Canadian sovereignty requirements for public sector and healthcare customers.
Integrated postal mail campaigns and cross-channel consent
AdMail.net integrated postal mail campaign option requires separate consent tracking for postal addresses versus email addresses under CASL and PIPEDA. An email opt-out does not automatically suppress postal mail sends unless cross-channel opt-out is configured. Configure per-channel consent scoping to match Canadian regulatory expectations. Postal mail campaigns fall outside CASL scope (CASL applies to commercial electronic messages) but PIPEDA privacy rules still apply to postal address handling.
