How do I send an HTML email?

I have successfully sent email in my web application using JMS, but the result only displays in plain text. I want the content to be able to display html. How do I do it? Here is roughly what I have:

Message msg = new MimeMessage(mailSession);
try{
    msg.setSubject("Test Notification");
    msg.setRecipient(Message.RecipientType.TO, new InternetAddress(sentTo, false));
    String message = "<div style=\"color:red;\">BRIDGEYE</div>";
    msg.setText(message);
    msg.setSentDate(new Date());
    Transport.send(msg);
}catch(MessagingException me){
    logger.log(Level.SEVERE, "sendEmailNotification: {0}", me.getMessage());
}

As per the Javadoc, the MimeMessage#setText() sets a default mime type of text/plain, while you need text/html. Rather use MimeMessage#setContent() instead.

message.setContent(someHtmlMessage, "text/html; charset=utf-8");

For additional details, see:

• GMail Media Queries

• GMail CSS Design

• CSS support in mail clients

Set content type. Look at this method.

message.setContent("<h1>Hello</h1>", "text/html");

If you are using Google app engine/Java, then use the following...

MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(SENDER_EMAIL_ADDRESS, "Admin"));
msg.addRecipient(Message.RecipientType.TO,
                 new InternetAddress(toAddress, "user");

msg.setSubject(subject,"UTF-8");

Multipart mp = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(message, "text/html");
mp.addBodyPart(htmlPart);
msg.setContent(mp);
Transport.send(msg);

Since JavaMail version 1.4, there is an overload of setText method that accepts the subtype.

// Passing null for second argument in order for the method to determine
// the actual charset on-the fly.
// If you know the charset, pass it. "utf-8" should be fine
msg.setText( message, null, "html" );

you have to call

msg.saveChanges();

after setting content type.

Take a look at http://commons.apache.org/email/ they have an HtmlEmail class that probably does exactly what you need.

You can find a complete and very simple java class for sending emails using Google(gmail) account here, Send email message using java application

It uses following properties

Properties props = new Properties();
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.port", "587");

The "loginVo.htmlBody(messageBodyPart);" will contain the html formatted designed information, but in mail does not receive it.

	loginVo.setSubject(subject);
//	loginVo.setBody(body);
	loginVo.setEmailAddress(emailAddress);
	SSLEmail sSSEmail=new SSLEmail();
	sSSEmail.sendEmail(loginVo);
	return "success";
 }

 }

I found this way not sure it works for all the CSS primitives

By setting the header property "Content-Type" to "text/html"

mimeMessage.setHeader("Content-Type", "text/html");

now I can do stuff like

mimeMessage.setHeader("Content-Type", "text/html");

mimeMessage.setText ("`<html><body><h1 style =\"color:blue;\">My first Header<h1></body></html>`")

You can use setText(java.lang.String text, boolean html) from MimeMessageHelper:

MimeMessage mimeMsg = javaMailSender.createMimeMessage();
MimeMessageHelper msgHelper = new MimeMessageHelper(mimeMsg, false, "utf-8");
boolean isHTML = true;
msgHelper.setText("<h1>some html</h1>", isHTML);

But you need to:

mimeMsg.saveChanges();

Before:

javaMailSender.send(mimeMsg);
