Drupal Symfony Mailer: Transforming Email Handling with Symfony Power

Drupal Symfony Mailer (Drupal Symfony Mailer | Drupal.org) is revolutionizing the way emails are handled in Drupal. Built on the robust Symfony Mailer library, it brings many powerful features, supporting everything from HTML mails and file attachments to embedded images, third-party delivery integrations, load balancing, failover, signing, encryption, and asynchronous sending. This new mail system introduces a fresh mail interface, which is expected to be adopted by an increasing number of future modules while still implementing the existing interface.

In a recent LinkedIn post by Grzegorz Pietrzak, the module's capabilities shine. Imagine managing various types of emails on your site, each requiring a distinct layout and containing numerous entity fields. The EmailBuilder plugin becomes the hero, defining email types and subtypes, processing parameters, and ensuring compatibility with the core mailing system.

Twig templates for HTML and plain formats provide flexibility, allowing easy overrides for any email type or subtype. The ability to define a render array for the email body opens up endless possibilities, with preprocessing options and compatibility with the Token module. Creating a sending policy also offers control over default senders and enables CSS inlining changes. With the EmailFactory's methods, injecting simplicity and elegance into your email handling has never been easier.
