import com.paubox.data.*;
import com.paubox.config.ConfigurationManager;

public class SendEmail {
    public static void main(String[] args) throws Exception {

        // Load credentials from config.properties
        ConfigurationManager.getProperties("config.properties");

        // Build the message
        Header header = new Header();
        header.setFrom("sender@yourdomain.com");
        header.setSubject("Your first Paubox email");

        Content content = new Content();
        content.setPlainText("This message was sent with the Paubox Java SDK.");

        Message message = new Message();
        message.setRecipients(new String[]{"recipient@example.com"});
        message.setHeader(header);
        message.setContent(content);

        // Send
        EmailService service = new EmailService();

GetEmailDispositionResponse disposition =
    service.getEmailDisposition(response.getSourceTrackingId());

for (MessageDeliveries delivery :
     disposition.getData().getMessage().getMessageDeliveries()) {
    System.out.println(delivery.getRecipient()
        + " → " + delivery.getStatus().getDeliveryStatus());
}
