Swift Mailer is a component-based, object-oriented PHP library for composing and sending emails via SMTP or Sendmail, with MIME message building, attachments, custom headers, and plugins. It was officially discontinued at the end of November 2021 and its successor is Symfony Mailer.
Use cases
- send emails from a PHP application
- send email over SMTP with authentication and encryption
- build MIME messages with attachments and HTML bodies
- add custom email headers in PHP
- throttle or batch bulk email sending from PHP
When to choose
- you are maintaining a legacy PHP codebase already built on Swift Mailer
- you need a battle-tested PHP mailer for an old PHP 7.x environment
When to avoid
- you are starting a new PHP project - use Symfony Mailer instead
- you need ongoing maintenance, security fixes, or modern PHP support
- you need built-in integrations with third-party email providers
