Dialog Insight is a Canadian marketing automation and CDP platform serving mid-market and enterprise B2C/B2B customers with omnichannel campaign orchestration, personalization, and CRM integration. The unsubscribe mechanism uses the [--UNSUBSCRIBE--] merge tag auto-injected into every campaign footer, and Dialog Insight emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with CASL enforcement. This guide covers the tag, the Canadian CDP model, and how to verify the setup end to end.

CASL enforcement and Francophone Canada
Dialog Insight Canadian CASL enforcement tracks express and implied consent classification. Contacts approaching implied consent 2-year expiration should be converted to express consent via re-permission campaigns. French and English language templates ship as first-class options for Francophone Canada (Quebec) and English Canada markets. Analogous to Envoke, AdMail.net, and Maropost Canadian regulatory-first patterns. Quebec-specific Loi 25 (formerly Bill 64) adds provincial privacy requirements on top of federal CASL and PIPEDA.
RFC 8058 one-click headers
Dialog Insight 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 > Profils expediteur. SPF and DKIM records must be verified. Canadian data residency defaults align with CASL and PIPEDA expectations for domestic senders.
CDP capabilities and personalization
Dialog Insight CDP capabilities unify contact data across email, SMS, push, and web channels. Personalization engines respect the opt-out flag when generating campaign content. An email opt-out can propagate to SMS and push suppression if cross-channel enforcement is configured. Configure per-channel consent scoping to match CASL and Quebec Loi 25 expectations for granular vs unified opt-out per Canadian jurisdictional requirements.
