Sending a HTML E-Mail

Sending a HTML email with Swift is just as easy as sending a plain-text email. You just need to tell the Message that’s it’s in HTML format and everything else is the same as if you were sending plain-text. HTML has it’s advantages in that it’s easy to create a layout with images and styles, but not all mail clients will read it, and if you’re not careful, you might be increasing the risk of being blocked as spam. See How to (legitimately) minimize being seen as spam.

A common pitfall is that people forget you need to use <br /> tags in place of real line breaks in HTML emails. I have had numerous support requests asking why everything was coming out on one line in the past ;)

<?php
 
require_once "lib/Swift.php";
require_once "lib/Swift/Connection/SMTP.php";
 
$swift =& new Swift(new Swift_Connection_SMTP("server.tld", 25));
 
$message =& new Swift_Message("Some subject", "Your message <u>here</u>", "text/html");
 
if ($swift->send($message, "recipient@domain.tld", "you@home.tld"))
{
    echo "Message sent";
}
else
{
    echo "Message failed to send";
}
 
//It's polite to do this when you're finished
$swift->disconnect();

You can alternatively set the text/html type on the message by using the following method:

$message =& new Swift_Message("Some subject", "Message goes here");
$message->setContentType("text/html");
