🚀 Overview

phpList is a mature open-source platform for sending newsletters, marketing campaigns, and notifications via email. It empowers users with full control over their data and communications, avoiding the limitations and costs of proprietary SaaS tools like Mailchimp.

It's built for non-profits, businesses, associations, and developers worldwide—used by 75,000+ organizations in 95 countries. Started in 2001 by phpList ltd. as a free, flexible alternative, it's community-driven with ongoing development funded by hosted services and donations.
