What is it?

SendPortal is an open-source, self-hosted email marketing application. It covers subscriber and list management, email campaigns, message tracking and reports, and supports multiple workspaces and domains within one installation. It is intended as an alternative to hosted newsletter platforms for people who want to run their own copy and control their data.

SendPortal sends mail through third-party email service providers, with integrations for Amazon SES, Postmark, SendGrid, Mailgun and Mailjet. The project is split into SendPortal Core, a package that can be added to an existing Laravel application that already handles user authentication, and the SendPortal application, which wraps Core as a standalone app with authentication and multiple workspaces.

The current V4 release requires PHP 8.3 or later, Laravel 13, and MySQL 5.7+ or PostgreSQL 10+. Projects on older PHP or Laravel versions are pointed to the V3 and V2 releases.
