Keila vs phpList
Both are free/open-source alternatives to Mailchimp. Here's how they stack up — verified facts, no spin.
Keila
Simple, privacy-friendly open-source newsletter tool.
Keila is an open-source newsletter application built in Elixir/Phoenix, designed to be a straightforward, privacy-conscious way to send campaigns and manage subscribers. It supports segmentation, templates, a form builder, and sending through providers like Amazon SES, Mailgun, Postmark, or plain SMTP. It is aimed at creators, small organizations, and anyone who wants a clean self-hosted newsletter tool without the complexity of a full marketing-automation suite; a paid managed cloud is also offered by its maintainers for those who prefer not to self-host.
phpList
Long-standing open-source newsletter manager for large lists.
phpList is one of the longest-running open-source newsletter applications (PHP/MySQL), built specifically for sending campaigns to large subscriber lists. It supports list management, segmentation, templates, bounce handling, and detailed sending controls, and works with any SMTP provider. It suits organizations and nonprofits that want a proven, no-frills self-hosted newsletter system and don't mind an interface that feels more utilitarian than modern SaaS tools; a paid hosted version is also available from the phpList team.
