Mautic

Mautic is open source marketing automation software for organizations that want to run campaigns on their own infrastructure. It handles email marketing and lead management, replacing vendor-hosted marketing tools while keeping your data under your control.

It supports fully integrated marketing campaigns, unlimited segmentation and automation, and multi-channel marketing without feature limits. Both frontend and backend are fully customizable, so you can build any integration you need without relying on third-party SaaS.

Mautic can be self-hosted, or you can deploy a trial in minutes. The GitHub version suits development and testing, while the production package with all libraries is available from mautic.org, installable via Composer or the pre-packaged build.
