Sarbacane is a French email marketing platform serving French and European SMBs and mid-market with drag-and-drop editor, SMS integration, and RGPD-first defaults. The unsubscribe mechanism uses the [DESABONNEMENT] merge tag auto-injected into every campaign footer, and Sarbacane emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with French RGPD/CNIL enforcement. This guide covers the tag, the French RGPD model, and how to verify the setup end to end.

French RGPD-first defaults
Sarbacane French RGPD compliance combined with CNIL enforcement quarantines imported contact lists without documented consent. French senders migrating from other ESPs must provide RGPD documentation for each contact. Analogous to Ecomail-fr, Courrielleur, and Mailjet French regulatory-first patterns. The [DESABONNEMENT] tag is French-native (unsubscribe in French) and templates ship with French-first UX for the domestic market. Sarbacane also supports English, Spanish, and Italian templates for European multi-market senders.
RFC 8058 one-click headers
Sarbacane 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 Parametres > Profils expediteur. SPF and DKIM records must be verified. French RGPD requires documented consent for imported lists and Sarbacane suppression files honor cross-campaign compliance.
SMS integration and French domestic market
Sarbacane SMS integration lets French senders coordinate email and SMS campaigns from a unified contact database. French SMS opt-out expectations under CNIL guidance are stricter than email since SMS is considered more intrusive. Configure SMS opt-out enforcement to honor STOP keyword replies immediately per French SMS best practices. Domestic focus on French SMBs and mid-market with French-language support and RGPD-native workflows differentiates Sarbacane from US-founded ESPs serving French customers as secondary market.
