DirectIQ is a US-based email marketing platform serving SMBs and mid-market with drag-and-drop editor, transactional API, and standard automation flows. The unsubscribe mechanism uses the {UNSUBSCRIBE_URL} merge tag auto-injected into every campaign footer, and DirectIQ emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the list level with US CAN-SPAM baseline enforcement. This guide covers the tag, the US SMB baseline, and how to verify the setup end to end.

How to add the unsubscribe tag in DirectIQ
Place the merge tag exactly as shown below in the email template. DirectIQ 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 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.
DirectIQ US CAN-SPAM baseline provides physical postal address, honest From line, and 10-business-day suppression. Senders targeting EU or Canadian audiences should configure double opt-in and consent documentation matching GDPR or CASL respectively. Transactional API sends bypass marketing consent per transactional exemption. Multi-account team collaboration features support agency use cases.

- Send a test message to a controlled Gmail address you own via the DirectIQ 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

{UNSUBSCRIBE_URL}. DirectIQ replaces it at send time with a signed URL scoped to the subscriber. - Wrap it in an anchor:

US CAN-SPAM baseline and international audience
DirectIQ US CAN-SPAM baseline provides physical postal address, honest From line, and 10-business-day suppression. Senders targeting EU or Canadian audiences should configure double opt-in and consent documentation matching GDPR or CASL respectively. Transactional API sends bypass marketing consent per transactional exemption. Multi-account team collaboration features support agency use cases with client account isolation.
RFC 8058 one-click headers
DirectIQ 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 > Sender identity. SPF and DKIM records must be verified. US data residency is the default.
Transactional API alongside marketing broadcasts
DirectIQ transactional API sends bypass marketing consent per transactional exemption (order confirmations, password resets, receipts). Configure the transactional API distinctly from marketing broadcast infrastructure to keep the classification clear. Some jurisdictions require distinct sending IPs or subdomains for transactional vs marketing to prevent cross-contamination of sender reputation and consent state.
Frequently Asked Questions
