Mautic

Mautic is an open-source marketing automation platform originally created by the founders of Joomla and now maintained by Acquia and a global community. It provides email campaign creation, drip nurture sequences, lead scoring, contact segmentation, landing pages, and dynamic content personalization. Because it is self-hosted and free under GPL, Mautic appeals to organizations wanting full data ownership, custom integrations, and no per-contact pricing. Hosted versions are available through providers like Acquia and various community partners worldwide.
