Answer 1

Since you are using MimeMessageHelper .Try below.

 MimeMessageHelper helper = new MimeMessageHelper(message,true);
 helper.setText(msg, true);

Use MimeMessageHelper.setText(emailContent,true) method. The boolean true flag indicates html content.

Answer 2

Try setting helper.setContent(htmlMsg, "text/html");

Answer 3

You didn't specified content type of mail. In which case it is sent in plain.

Try setting content type

helper.setContent(htmlMsg, "text/html;  charset=\"utf-8\"");

Now when you open this mail with any email client, it will read it in html format.

You can also set multiple formats by using MimeMultitype

Multipart multipart = new MimeMultipart("alternative");
BodyPart messageBodyPart;

// PLAIN TEXT
messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(textBody, "text/plain; charset=\"utf-8\"");
multipart.addBodyPart(messageBodyPart);

// HTML TEXT
messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(htmlBody, "text/html; charset=\"utf-8\"");
multipart.addBodyPart(messageBodyPart);

message.setContent(multipart);

This worked for me, I have changed two line code, Thank you all for your contribution

private void sendEmail(String email,String name) throws Exception{
    Thread thread=new Thread(){
        @Override
        public void run() {

            try{
                String msg="Dear<b> "+name.toUpperCase()+" </b>,<p> On Behalf of someone we would like to wish you a Many many Happy returns of the day</p> <p style=color:red;>Happy Birthday and Have a Great Day.</p>\n \n Thank You!";

                MimeMessage message = mailSender.createMimeMessage();
                MimeMessageHelper helper = new MimeMessageHelper(message,true);
                helper.setTo(email);
                helper.setText(msg);
                message.setContent(msg, "text/html");                   
                helper.setSubject("BirthDay");
                mailSender.send(message);

            }catch (Exception e){}
        }
    };
    thread.start();

}
