phpList

phpList runs newsletters and email marketing campaigns, combining subscriber management, bounced message handling, and plugin support in one open source program. It is designed for individuals and organizations that need to maintain email lists, process bounces, and extend newsletter software through plugins. The program is licensed under AGPL-3.0. phpList may serve as an alternative to paid newsletter and email marketing software, though no specific commercial product is a known direct replacement. Its confirmed capabilities cover newsletters, email marketing, subscriber lists, bounce management, and plugins. Capabilities outside those areas are unknown, and no feature-by-feature comparison with paid products is available. This limits how closely individuals and organizations can compare phpList with commercial options before choosing newsletter software for an email campaign.
