In simple English
This tool lets you run your own email marketing service on your own server. You can send newsletters, manage subscriber lists and track opens without paying a third-party platform. It connects to popular email delivery services to actually send the messages. You need a server and some technical knowledge to set it up and keep it running.
What it is
SendPortal is an open-source, self-hosted email marketing application built on the PHP (a programming language used to build websites) framework Laravel (a collection of reusable code for building PHP web apps). It provides a dashboard for managing campaigns, subscribers and delivery providers.
