Maillayer

Maillayer is a self-hosted email marketing platform that replaces Mailchimp, enabling users to send unlimited emails through providers like Amazon SES, SendGrid, or Mailgun. It targets developers, IT teams, and marketers in small to mid-sized businesses who want full control over their data and infrastructure. The product is positioned as a one-time purchase with lifetime updates, contrasting with subscription-based SaaS alternatives, and runs on a single Docker container with SQLite, eliminating the need for external services.
