Starting email marketing can feel expensive, especially with popular tools charging monthly fees. But there are powerful open source email marketing tools that let you send bulk emails, manage lists, and automate campaigns—all without monthly subscriptions. These platforms are perfect for startups, small businesses, and anyone who wants to control their data and costs.
