Simplero is a Danish creator platform combining course hosting, membership sites, email marketing, and community features for online coaches, course creators, and infopreneurs. The unsubscribe mechanism uses the {{unsubscribe_url}} merge tag auto-injected into every campaign footer, and Simplero emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with course customer relationship tracking. This guide covers the tag, the Danish creator platform model, and how to verify the setup end to end.

Course customer consent versus marketing consent
Simplero creator platform combines marketing consent with course access, similar to Kajabi. A contact who unsubscribes from marketing emails retains access to purchased courses since course-related notifications qualify for transactional exemption. Danish-founded platform brings EU GDPR-first defaults with course customer records tracked separately from marketing consent state. This dual-consent model matches EU creator regulatory expectations better than pure US-founded creator platforms.
RFC 8058 one-click headers
Simplero 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 > Email. SPF and DKIM records must be verified. Course creators using custom domains for their Simplero site should configure per-domain authentication to keep one-click compliance consistent across course brands.
Automations and membership community
Simplero automations (drip campaigns, welcome sequences, launch campaigns) respect the contact opt-out flag at every send step. A contact who unsubscribes exits all automations automatically. Membership community integration lets creators reach opted-out contacts through in-community posts without violating email opt-out preferences. Danish creator platform focus with EU regulatory defaults appeals to European course creators uncomfortable with US-founded creator platforms.
