I\'ve problem with sending HTML mails with PHPMailer. I make a Smarty template and I got all the HTML code from it. But when I send mail, I got the mail without included CSS
I assume you have your CSS in an external file, if so the easiest solution would be to simply move it into the html header inside the mail.
However, css support in email clients is very wonky, so it might just be crappy rendering on their part.
