JavaScript is a programming language that you can use for both front-end and back-end development. When the name JavaScript is used in the context of sending emails, Node.js is the first thing that comes to mind. We also blogged about how to send email with Node.js. In this article, we want to change the perspective from server side to client side. Let’s see how you can use JS to send emails from an application without a backend.

You cannot send emails using only JavaScript code due to the lack of support for server sockets. For this, you need a server-side language that talks to the SMTP server. You can use JS in conjunction with server scripts that send emails from the browser based on your requests. This is the value we will introduce below.
Traditionally, the server side of the application is responsible for sending emails. You need to setup the server using back end technology. The client side sends a request to the server side, which creates an email and sends it to the SMTP server. If you’re curious about what happens with email after that, read our blog post, SMTP Relay.
So, why would anyone want to go the other way and send emails from the client side using JavaScript? Such an approach is useful for creating contact forms or other forms of user interaction in web applications that allow your application to send emails without refreshing the page the user interacts with. Plus, you don’t have to mess with server coding. This is a strong argument if your web application only uses email sending for contact forms. Below, you’ll find some options for enabling your app to send email from the client side.

However, an email sandbox is more than just a virtual inbox. Rather, it is an email testing tool used by developers to validate emails and debug/fix any issues with them through inspection and debugging.
Thanks to the email sandbox, test emails detected during staging will not reach real recipients. That means, no matter how long or complicated your email testing process is, at that point, you’ll never run the risk of spamming a genuine recipient with them.
Email Sandbox users have at their disposal, automated test flows and scenarios, checking spam scores, blacklist reports, HTML/CSS validation and many more features.
We’ll talk about HTML/CSS validation in depth after we touch on HTML emails. For now, let’s go back to the step of sending your first test email with SmtpJS while using Email Sandbox’s SMTP server credentials.
