Unofficial N8N node for MailWizz — subscribers, lists, campaigns, and transactionals in a single connector.
Open-source NPM package shipping an N8N node for MailWizz, one of the most-used self-hosted email platforms. The node exposes the key operations (subscriber management, lists, campaigns, transactional sends) through a uniform interface with typed parameters. Maintained in production, the package crosses 25,000 NPM downloads and powers several N8N automation chains.
N8N ships no native MailWizz connector. Self-hosted users had to hand-wire HTTP endpoints, manage API authentication and reproduce pagination and retry logic in every workflow.
Type-safe N8N node in TypeScript covering the main operations: create/update/delete subscriber, list management, campaign send, transactional send. Encapsulated API auth, exponential backoff retry, automatic pagination. Published on the public N8N registry and NPM, with documentation, workflow examples and integration tests.
