phpList

phpList is a self‑hosted, open‑source platform for creating, sending and analysing email newsletters and marketing campaigns. It offers a responsive web interface and command‑line tools, allowing users to import subscriber lists from CSV or Excel, segment audiences, personalise content per recipient, and schedule or repeat campaigns. The system tracks delivery outcomes, provides real‑time analytics on opens and clicks, and automatically processes bounces using configurable policies.

The software is designed for organisations that need granular control over large‑scale email distribution without relying on proprietary services. Its plugin architecture supports extensions such as Amazon SES integration, RSS‑driven newsletters, attachment handling and domain‑based throttling to comply with host policies. phpList can be deployed on a private server or used through a hosted offering, with data migration between the two options.

Having been adopted in dozens of countries and handling billions of messages annually, phpList emphasizes extensibility, multilingual support and community‑driven development under the AGPL‑3.0 license.
