On the ZendCasts.com site today there's a new screencast posted looking at using the Zend_Mail component of the Zend Framework to easy (and painlessly) send HTML emails.
Here’s a quick video explaining how quickly and easy it is to write designer-friendly HTML emails using Zend_View and Zend_Mail.
You can watch the screencast via their in-page player and grab a copy of the project to follow along.
