Symfony Mailer is a PHP component for creating and sending emails via SMTP or third-party transports. It supports multipart messages, attachments, Twig templating, CSS inlining, and message signing/encryption.

Use cases

• send emails from a php application
• send transactional emails over smtp
• render html email templates with twig
• attach files to emails in php
• send emails via third-party providers like mailgun or sendgrid
• sign and encrypt email messages

When to choose

• you are building a PHP or Symfony application that needs to send email
• you want a modern, well-maintained alternative to Swiftmailer
• you need Twig templating, CSS inlining, or multipart email support
• you need pluggable transports for SMTP or email delivery services

When to avoid

• your project is not in PHP
• you only need a full email server or inbox client rather than a sending library
• you need bulk marketing email campaign management rather than transactional sending
