How To Send Email Using Javascript – 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, the first thing that comes to mind is Node.js. We even blogged about how to send emails with Node.js. In this article, we want to change the perspective from the server side to the client side. Let’s explore how you can use JS to send emails from an app that has no backend.
Due to the lack of support for server sockets, you cannot send emails using only JavaScript code. To do this, you need a server-side language that communicates with the SMTP server. You can use JS with a server script that sends emails from the browser based on your request. This is the value we present below.
How To Send Email Using Javascript
Traditionally, the server side of a standard application is responsible for sending emails. You need to set up the server using backend 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 wondering what happens to the email after that, read our blog post SMTP relay.
Html Form To Email Using Javascript And Smtp Server 🚀
So why would anyone be willing to go the other way and send us directly from the client side using JavaScript? This approach is quite useful for creating contact forms or other types of user interactions in web applications that allow your application to send an email without refreshing the page the user is interacting with. Plus, you don’t have to mess with server coding. This is a strong argument if your web application only uses email for contact forms. Below are some options on how to get the app to send email from the client side.
Since you can’t send emails directly with JS, you can tell the browser to open the default mail client to do so. Technically it is
The method doesn’t send emails directly from the browser, but it gets the job done. See how the following code example works:
Once the data is transferred, the browser opens the default mail client. In our case, it’s Gmail.
Send Email To The Inbox In A More Reliable Way
SmtpJS is a free library that you can use to send emails via JavaScript. All you need is an SMTP server and some manipulations to get things done.
But before proceeding with production, you need to test the production. Therefore, we use the SMTP server credentials provided by Email Sandbox to act as a virtual mailbox to receive test emails.
But an email sandbox is more than just a virtual mailbox. Instead, it is an email testing tool that developers use to validate emails and troubleshoot/resolve issues in emails through inspection and debugging.
Thanks to the email sandbox, staged test emails never reach the actual recipients. This means that no matter how long or complex your email testing process is, you’ll never run the risk of spamming real recipients during that time.
Nodejs Send Smtp Email
Email sandboxing, automated test flows and scenarios, spam score checking, blacklist reports, HTML/CSS validation and other features are available to users.
Let’s talk in detail about HTML/CSS validation after touching HTML emails. Now let’s go back to the steps to send the first test email with SmtpJS using the email sandbox SMTP server credentials.
The downside of the code example above is that your username and password are visible in the client-side script. This can be fixed by using the encryption option provided by SmtpJS. So, click Encrypt your SMTP credentials and fill in the required fields.
After that, press Generate Security Token to use in JS function instead of SMTP server settings:

Now let’s take it a step further and show you code examples for sending an HTML email and an email with an attachment.
With HTML Check, you can see the support level of the best email clients for your HTML/CSS attributes. It gives you an overview of how your emails are placed in different mailboxes.
For each email analyzed by the HTML checker, a report is generated that includes market support percentage analysis at the top and email customer support for individual HTML elements / CSS rules at the bottom, links to lines containing error codes and notes with additional information.
So, once you’ve sent your HTML email using the code below, validate that email using the HTML validation feature in the email sandbox.
How To Create A Web Form That Can Send Emails Using Your Gmail Account
EmailJS.com was already mentioned in our blog post Sending Emails with ReactJS. This service allows you to connect your email service, create an email template and send it from JavaScript without any server code. So let’s look at the scope.
One of the main advantages of EmailJS.com is that typical email attributes are hidden. The template contains a recipient field and cannot be overridden from JS, so you send the template you set up earlier.
Let’s test if EmailJS.com is working by sending an email directly from the browser. We have created a virtual mailbox with an email sandbox and created a simple template. Now we need to create an HTML file with the following code:
EmailJS offers a free subscription plan that allows you to send up to 200 emails per month using only two templates. In addition, you have a limited contact list and email size (up to 50 Kb). Higher quotas are available for paid subscriptions: Personal ($5/month), Professional ($15/month) and Business ($50/month).

If you need fast, easy, and automated email sending, you should use the Email API. Depending on the API you use, you may also enjoy email analytics.
The email API that fits the above description is the one offered as part of its email delivery platform with the email sandbox.
Email API is best described as a reliable email sending service that you can set up and use without any problems.
With a sending speed of up to ~10,000 emails per second, the Email API meets your sending needs. And thanks to the many applied analysis functions, it also allows you to find and eliminate sending problems at an early stage that can degrade your email delivery.
Email Notifications For Google Forms
First, you have timely delivery alerts that notify you of delivery issues and let you know where to look for it. You will also receive weekly reports on your achievements.
Next are dashboards with critical metrics that give you insight into the health of your email infrastructure.
In addition to the benefits of actionable analytics, email API users also have access to webhooks, dedicated IPs, automatic IP warming, blacklists, and more.
So to start using the email API in your JavaScript application, you need to do the following.

With SMTP support, you can take a different approach to API integration and simply set up your project, application, or email service as an SMTP server to start issuing emails.
SMTP credentials are very easy to get from the API and SMTP integration under Mail API->Sending Domain.
Although sending emails is a server-side thing, you can avoid doing server-side coding. SmtpJS and EmailJS are two solutions that can be implemented to simplify your front-end and send emails. EmailJS is better because it hides typical email attributes and you can send any templates you’ve set up before. The mailto method: is different, but can be useful in some cases.

If you’re writing a front-end web application with Javascript, you’ll most likely need to create a contact form. A contact form is an important part of marketing, lead generation and consumer communication.
Gmail: Sending Email
Not only does a contact form drive sales, but it also helps you stay in touch with users with issues so you can quickly and efficiently fix bugs and provide customer support.
Sending an email from a front-end Javascript application is not as simple as sending a normal AJAX request. There are a few more steps involved because email communications need to remain secure. Violating email protocols puts you at risk of becoming a spammer.
This article looks at two ways to send emails from a Javascript application: using the mailto HTML attribute and using SMTPJS with ElasticEmail.
A series of abstract APIs have been created to save you time. You don’t need to be an expert in email authentication, IP address geolocation, etc. Just focus on writing valuable code for your app or business, and we’ll take care of the rest.
Send Mail Using Javascript
SMTP (or Simple Mail Transfer Protocol) is the communication layer that handles email. It describes the rules for sending and receiving e-mail, just as HTTP (Hyper Text Transfer Protocol) describes the rules for sending and receiving data packets on the web.
