SendPortal

SendPortal is open-source, self-hosted email marketing and newsletter software. An organization can run its own email marketing application instead of a hosted-only service, with subscriber and list management, campaign sending, tracking, and reports in one web application.

Campaigns can be organized across multiple workspaces and domains. SendPortal integrates with Amazon SES, Postmark, Sendgrid, Mailgun, and Mailjet, so the application manages campaigns while the delivery provider sends the messages.

The stand-alone application wraps SendPortal Core and adds user authentication and multiple workspaces. SendPortal Core can also be embedded in an existing Laravel app that already handles authentication. Version 3 requires PHP 8.2+, Laravel 10+, and MySQL 5.7+ or PostgreSQL 9.4+.
