Mailchimp is published by Intuit. This page compares only projects with an explicit relationship to it; shared categories alone never create an alternative claim.
Recommended order uses OpenAlternative organic alternatives v4 (version 4). Relationship confidence, category fit, logarithmic popularity, as-of maintenance and freshness, bounded anomaly quarantine, and known-data penalties. Payment is fixed at zero.
A hard constraint removes a Project only when its stored fact is known and conflicts. Unknown facts remain visible, are called out below, and never become a negative claim.
Self-hosted newsletter and mailing list manager
Listmonk is a single Go binary and a Postgres database that handles subscriber lists, segmentation, campaigns, and bounce processing at a scale that would be expensive on a hosted platform.
Multi-channel notification infrastructure for applications
Novu takes the notification logic that usually ends up scattered across a codebase - which channel, which template, which quiet hours, which digest window - and puts it behind one API and one workflow editor.
Groups appear only when at least two credible projects qualify.
