SubscribeFlow Documentation
Build better email subscription experiences.
SubscribeFlow is an API-first subscription management platform. It wraps the Resend email API and adds subscriber management, tag-based preferences, and a self-service preference center -- all with DSGVO/DSG compliance built in.
The key difference: your subscribers can actively add new interests and tags themselves, not just unsubscribe from predefined lists.
-
Subscriber Management
Full CRUD for subscribers with metadata, tags, and preference tracking. Import existing lists or grow organically through the preference center.
-
Preference Center
A self-service portal where subscribers manage their own interests. DSGVO-compliant with data export and account deletion built in.
-
API-First
REST API with official Python and TypeScript SDKs. MCP integration lets AI agents manage subscriptions on your behalf.
