// EDITOR'S TAKE
Mautic is the only one here that seriously covers the automation side, with segments, drip campaigns and lead scoring, but it is heavy to host and its ecommerce integrations take work. Listmonk is dramatically faster and simpler for sending large campaigns yet has no flow builder, and Keila sits between them as a manageable self-hosted newsletter tool.
