Swift Mailer is a feature-rich PHP mailer library for sending e-mails from PHP websites and applications.
It does not rely on PHP’s native mail() class which consumes high resources. Instead, Swift communicates directly with an SMTP server or a MTA binary to send mail quickly and efficiently.
Swift supports event-driven plugins which offer you the opportunity to really take control of the library and set this mailer apart from everything else that’s out there.
