Enhanced fork of the N8N MailWizz node: advanced operations on lists, segments, and tags.

Context2026

Enhanced fork of the N8N MailWizz node: advanced operations on lists, segments, and tags.

Enriched fork of the N8N MailWizz node that adds advanced operations missing from the main package: fine-grained segment management, tags, custom fields and unsubscribe webhooks. Designed for agency use cases orchestrating multiple MailWizz accounts in parallel. Version 2.1.13 stabilizes API coverage and formalizes types to ease integration into production-grade N8N workflows.

ChallengeBefore intervention

Blocked identified.

The official N8N MailWizz node did not cover agency operations: dynamic segments, multiple tags, custom fields, webhook-driven unsubscribes. Advanced users had to maintain their own local patches.

Risk addressedAuthor & open-source maintainer · Backend
ApproachAfter delivery

Answer built.

Typed fork published separately with the missing operations, while keeping surface compatibility with the official node. Integration tests against a MailWizz mock to stabilize contracts. The package is used in production on agency client automation chains and published on NPM as version 2.1.13.
