Choosing an email marketing tool means balancing practical fit with evidence that a project is maintained and shipping. This ranking uses the supplied ToolVitals scores, health and shipping scores, openness and license labels, and GitHub star counts for context.
The list covers open/source-visible tools and is ordered by ToolVitals score descending, with health and shipping used for equal composite scores. GitHub stars are context only and do not determine the ranking.
