Where it fits
Teams with the capacity to operate campaigns and email delivery responsibly.
Trade-offs and limitations
Email delivery is a separate service and cost. Consent, suppression lists and deliverability must survive migration.
Deployment and technology
PHP · MySQL/MariaDB. Self-hosting requires a supported deployment, capacity planning and a named maintainer. Consult the official installation guide for the current version.
Portability and integration
| API | REST API |
|---|---|
| Authentication | Validate SAML or other SSO support for your version |
| Data export | Contact exports, API and database backups |
Migration considerations
Move consent evidence and unsubscribes first; rebuild and test segments, forms and campaign triggers.
Security and ongoing costs
Budget for infrastructure, implementation, monitoring, patching, backups, restore tests and user support. Check the supported release and current advisories with the project. An open licence is not a security guarantee.
Freedom score and exit difficulty
A complete, evidence-backed assessment of all 15 criteria is required before publishing a score. Exit difficulty depends on your customisations, data model, integrations and operating documentation. This profile does not claim a hands-on benchmark or a complete security assessment.
