The Next Generation

PHPMailer Pro is a new project that follows the concept of PHPMailer. I want to make it clear: PHPMailer Pro is not a competitor to PHPMailer. There were many requests for a slimmed down email transport PHPMailer Pro fulfills that need, with full functionality. I have been using a version of PHPMailer Pro for quite some time now. It is easy to use and implement on just about any server and just about any environment.

Before you proceed, PHPMailer Pro is NOT compatible with PHPMailer properties and methods. Despite this, you can use it as a drop in replacement for PHPMailer ... I have a tutorial on how to do that without any modifications to your scripts – using a compatibility script (an extension to PHPMailer Pro).

PHPMailer Pro supports Qmail, Sendmail, Postfix, Exim and SMTP. Previous versions did not support SMTP natively ... with this release PHPMailer Pro supports built-in SMTP (no external dependencies).

PHPMailer Pro is a single file (less than 85Kb) solution that does what it is supposed to and does it elegantly and does it well.

We also have an updated DKIM creation utility available. It will: create your DNS entry text you can copy and paste; create a passphrase; and create the PHPMailer Pro code you need to fully utilize DKIM. You can get more information here: DomainKeys Identified Mail.

PHPMailer Pro supports PHP8.0 (and up) and licensed under MIT.
