Hi, I am trying to create some html form with html email messages to the user. In the html email, I need to have images, links and css embedded in the email. I used php mail() function before but want to use something more reliable and secure. I have done some research and found swiftmail and phpmailer. Can someone please tell me which one is easier to implement for beginner and still able to include images, links, css etc? Which one is more secure? and if possible some links to sample code on how to do this.

Thanks.
