How to send Emails with SMTP JS

To send an email with SMTP.js in JavaScript, you can follow these steps:

1. Include the SMTP.js library in your HTML file. You can download the library from the official SMTP.js GitHub repository: https://github.com/EmailJS/SMTP.js
2. Create an HTML form with input fields for the sender’s email address, recipient’s email address, subject, and message body.
3. In your JavaScript code, initialize the SMTP client by providing the SMTP server details, such as the hostname, username, password, and port number. For example:

var smtp = new SMTPClient({
  host: 'smtp.example.com',
  username: 'your_username',
  password: 'your_password',
  port: 587
});

Make sure to replace ‘smtp.example.com’ with the hostname of your SMTP server, ‘your_username’ with your SMTP username, and ‘your_password’ with your SMTP password. Adjust the port number according to your server’s configuration.

4. Attach an event listener to the form submit button to handle the email sending. In the event listener, retrieve the values from the form fields and use the SMTP client’s send method to send the email. For example:

document.getElementById('sendButton').addEventListener('click', function() {
  var senderEmail = document.getElementById('senderEmail').value;
  var recipientEmail = document.getElementById('recipientEmail').value;
  var subject = document.getElementById('subject').value;
  var message = document.getElementById('message').value;

  var email = {
    from: senderEmail,
    to: recipientEmail,
    subject: subject,
    body: message
  };

  smtp.send(email, function(success, response) {
    if (success) {
      alert('Email sent successfully!');
    } else {
      alert('Email failed to send. Error: ' + response);
    }
  });
});

Make sure to replace ‘sendButton’, ‘senderEmail’, ‘recipientEmail’, ‘subject’, and ‘message’ with the corresponding                  IDs of your form elements.

5. Test your code by filling in the form fields and clicking the submit button. The email should be sent using the

provided SMTP server.
Note: SMTP.js is a client-side library, so it sends emails directly from the client’s browser. It’s important to keep                   your SMTP server credentials secure and avoid exposing them in your JavaScript code. Additionally, some SMTP                 servers may have restrictions or require additional configuration for sending emails from client applications.

6. Ensure that you have a valid SMTP server to use. You can either use your own SMTP server or use a third-party SMTP service. Make sure you have the correct SMTP server details (hostname, username, password, and port) before proceeding.
7. Once you have completed the steps mentioned earlier, save your HTML file and open it in a web browser. Fill in the form fields with the appropriate information, such as the sender’s email address, recipient’s email address, subject, and message body.
8. Click the submit button on the form. The JavaScript code will be executed, and the SMTP.js library will attempt to establish a connection with the SMTP server and send the email using the provided information.
9. If the email is sent successfully, an alert box will pop up with the message “Email sent successfully!”. Otherwise, if there’s an error during the sending process, an alert box will display an error message.
10. You can customize the handling of success and error scenarios based on your application’s requirements. For example, instead of using alert boxes, you could update the page dynamically to show success or error messages to the user.
11. It’s important to test the email sending functionality thoroughly, including different scenarios such as invalid email addresses or empty form fields, to ensure your application handles them appropriately.
12. Remember to handle any errors or exceptions that may occur during the email sending process. You can use try-catch blocks or error handling mechanisms to gracefully handle any potential issues.

That’s it! You’ve successfully sent an email using SMTP.js in JavaScript. Make sure to thoroughly test and validate your implementation to ensure it meets your specific requirements.
