Hey Yashmika, to send a report through email, you can use Java Mail Jar files with Selenium. It comes with a library which allows you to create session and send mails though SMTP:
package sendReportMailSelenium;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class SendMailSSLWithAttachment {
 public static void main(String[] args) {
  // Create object of Property file
  Properties props = new Properties();
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.socketFactory.port", "465");
  props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.port", "465");
  // This will handle the complete authentication
  Session session = Session.getDefaultInstance(props,
    new javax.mail.Authenticator() {
     protected PasswordAuthentication getPasswordAuthentication() {
     return new PasswordAuthentication("your_email", "your_password");
     }
    });
  try {
   // Create object of MimeMessage class
   Message message = new MimeMessage(session);
   message.setFrom(new InternetAddress("anvi.rajawat@gmail.com"));
   message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("anvi.rajawat@gmail.com"));
   message.setSubject("Testing Subject");
   // Create object to add multimedia type content
   BodyPart messageBodyPart1 = new MimeBodyPart();
   messageBodyPart1.setText("This is message body");
   // Create another object to add another content
   MimeBodyPart messageBodyPart2 = new MimeBodyPart();
   String filename = "D:\\report.xlsx";
   // Create data source and pass the filename
   DataSource source = new FileDataSource(filename);
   // set the handler
   messageBodyPart2.setDataHandler(new DataHandler(source));
   // set the file
   messageBodyPart2.setFileName(filename);
   // Create object of MimeMultipart class
   Multipart multipart = new MimeMultipart();
   // add body part 1
   multipart.addBodyPart(messageBodyPart2);
   // add body part 2
   multipart.addBodyPart(messageBodyPart1);
   // set the content
   message.setContent(multipart);
   // finally send the email
   Transport.send(message);
   System.out.println("=====Email Sent=====");
  } catch (MessagingException e) {
   throw new RuntimeException(e);
  }
 }
}
