Hi 

Create a costume OSGI service to send email to bulk:

Link:- http://www.roytuts.com/send-bulk-mails-using-java/

// List<String> emails = new ArrayList<String>(); emails.add("email1@email.com"); emails.add("email2@email.com"); emails.add("email3@email.com"); emails.add("email4@email.com"); emails.add("email5@email.com"); //email subject String subject = "Test Email"; //message which is to be sent String message = "Test Email Message"; //send the email to multiple recipients sendEmail(subject, emails, message); public static void sendEmail(final String subject, final List<String> emailToAddresses, final String emailBodyText) { // from email address final String username = "your email address"; // make sure you put your correct password final String password = "your email password"; // smtp email server final String smtpHost = "your mail smtp server host"; // We will put some properties for smtp configurations Properties props = new Properties(); // do not change - start props.put("mail.smtp.user", "username"); props.put("mail.smtp.host", smtpHost); // props.put("mail.debug", "true"); props.put("mail.smtp.auth", "true"); // do not change - end // we authentcate using your email and password and on successful // we create the session Session session = Session.getInstance(props, new javax.mail.Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); String emails = null; try { // we create new message Message message = new MimeMessage(session); // set the from 'email address' message.setFrom(new InternetAddress(username)); // set email subject message.setSubject(subject); // set email message // this will send html mail to the intended recipients // if you do not want to send html mail then you do not need to wrap the message inside html tags String content = "<html> <body> "; content += emailBodyText + " "; content += " "; content += "</body> </html>"; message.setContent(content, "text/html"); // form all emails in a comma separated string StringBuilder sb = new StringBuilder(); int i = 0; for (String email : emailToAddresses) { sb.append(email); i++; if (emailToAddresses.size() > i) { sb.append(", "); } } emails = sb.toString(); // set 'to email address' // you can set also CC or TO for recipient type message.setRecipients(Message.RecipientType.BCC, InternetAddress.parse(sb.toString())); System.out.println("Sending Email to " + emails + " from " + username + " with Subject - " + subject); // send the email Transport.send(message); System.out.println("Email successfully sent to " + emails); } catch (MessagingException e) { System.out.println("Email sending failed to " + emails); System.out.println(e); } }

 

I hope this would help you.

Thanks and Regards
