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

French RGPD-first defaults

Sendethic French RGPD-first defaults quarantine imported contact lists without documented consent. French senders migrating from other ESPs must provide RGPD documentation for each contact. Analogous to Sarbacane, Ecomail-fr, 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. CNIL enforcement provides meaningful fines for violations.

RFC 8058 one-click headers

Sendethic 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.

Marketing automation and transactional API

Sendethic combines marketing automation flows with transactional API for French mid-market senders needing both broadcast and per-user transactional email. Transactional sends (order confirmations, password resets) bypass marketing opt-out per transactional exemption. Configure transactional API distinctly from marketing broadcast to keep the classification clear per CNIL guidance.
