We are pleased to announce the release of an official Postmark transport for Swiftmailer, a de facto standard for sending complex emails from PHP applications. The new transport offers improved deliverability rates, tracking, and bounce handling, requiring only a few lines of code to integrate into existing applications. It also includes an adapter for seamless integration with any application. To install the transport, simply run `composer require wildbit/swiftmailer-postmar` in your terminal.
