OpenEMM
OpenEMM is web-based open-source software for email marketing and automation, including newsletters and transactional or date-driven messages. Its tools include a campaign manager, calendar reminders and comments, responsive templates, recipient status history, and profile enrichment based on recipient reactions. It also provides bounce management, real-time opener and click statistics, behavior-based target groups, web forms, a multiqueue mail backend, web services, and a plugin interface. Integrations include Make and n8n, alongside HTTP request endpoints and import and export options. OpenEMM is self-hosted, with operation on a user's premises, through a hosting provider, or in a data center. The download page lists Linux servers and Windows or Mac servers via VirtualBox. From OpenEMM 2019 Spring, releases use the GNU AGPLv3 license. The plan costs nothing, with no limits on recipients, mailing lists, or dispatches. A three-day demo is available, but mailings cannot be sent from that account.
