What is EmailJS?
EmailJS is a free and secure client-side service that allows you to generate custom emails from your application! I will explain step by step how I implemented EmailJS into my React portfolio with this simple demo.
EmailJS Set up
First, you have to make an account at https://www.emailjs.com/
From there under Email Services located at side nav bar, click Add New Service under the header “Email Services”.
A pop up modal will appear where you can choose your email service to connect from. For this demo, I just connected my personal gmail account. Next, name your service and service ID. Note that the service ID will be important later when we code so I recommend renaming it to fit your needs. Finally connect your email account and create your service. I suggest keeping the “send test email” checked as EmailJS will send you a test email to ensure everything is in working order!
The final set up will be the create an email template. Navigate to "Email Templates" in the side nav bar and create a new template. For this demo, I kept it simple so the only fields I'll add is the contact's name, message and email.
Notice that the properties I wanted (name, message, email) are in double curly brackets. This is the object keys we will implement later in our code! Once you have the format you want, navigate to settings and name your template ID.
Just like the service ID we will utilize this ID later in our code. Make sure to save your changes here! Last ID we need is our User ID. You can find it under Integration in the nav bar under API keys.
Let's finally get to the fun part. Our React implementation!
React Set Up
First, lets create a React act. Run create-react-app in your terminal to generate a react starter scaffold.
Next, run npm i emailjs-com to install the EmailJS library (make
sure you are in your app directory).
I started by creating a Contact.js component to create a simple contact form in Bootstrap5. I added a link and script in index.html under the public directory.

<div id="root"></div>
</body>
</html>
This seemed to work best for me but you can see other implementations to set up Boostrap5 here.
If you create a new component like I did, make sure to import the file and add it to App.js!
import React from "react";
import Contact from "./Contact";
function App() {
return(
<div>
<Contact />
</div>
)
}
export default App;
Contact Form
Here is how I created my contact form with the fields I wanted: Name, email and message with a simple Send button in Contact.js
import React from "react";
function Contact() {
return (
<div className="row m-5">
<div className="col-md-6 col-md">
<h2>Contact</h2>
<p>I would love to connect. Send me an email!</p>
<form >
<div className="row">
<div className="col-sm-6 form-group">
<label htmlFor="name">Name:</label>
<input
type="text"
className="form-control"
name="name"
required
/>
</div>
<div className="col-sm-6 form-group">
<label htmlFor="email">Email:</label>
<input
type="email"
className="form-control"
name="email"
required
/>
</div>
</div>
<div className="row">
<div className="col-sm-12">
<label htmlFor="message">Message:</label>
<textarea
className="form-control"
type="text"
name="message"
maxLength="6000"
rows="7"
required
></textarea>
</div>
</div>
<div className="row mt-2">
<div className="col-sm-12 form-group">
<button type="submit" className="btn btn-primary">
Send
</button>
</div>
</div>
</form>
</div>
</div>
);
}
export default Contact;
Contact form should now look like this!
EmailJS integration
Now lets import useState from react and emailjs at the top of Contact.js
import React, { useState } from "react";
import * as emailjs from "emailjs-com";
Next, we will create our initial form state of our contact form properties which starts as blank (empty quotes). Then create an event handler to handle each change for name, email and message.
function Contact() {
const initialFormState = {
name: "",
email: "",
message: "",
};
const [contactData, setContactData] = useState({ ...initialFormState });
const handleChange = ({ target }) => {
setContactData({
...contactData,
[target.name]: target.value,
});
};
//simplified for brevity
......
}
Next we create our submit handler which does all the work to handle our contact form submission. Here you input your service ID, template ID, and User ID. (Be sure to put in quotes and remove curly braces).
const handleSubmit = (e) => {
e.preventDefault();
emailjs
.sendForm(
{Service ID in quotes},
{Template ID in quotes},
e.target,
{USER ID in quotes},
)
.then(
(result) => {
console.log(result.text);
},
(error) => {
console.log(error.text);
},
);
//reset the form after submission
setContactData({ ...initialFormState });
};
Now with all your event handlers created, be sure to add value and onChange properties in your input and text area tags on the contact form along with onSubmit in your form tag.
And that is it! Here is what the final component looks like:
import React, { useState } from "react";
import * as emailjs from "emailjs-com";
function Contact() {
const initialFormState = {
name: "",
email: "",
message: "",
};
const [contactData, setContactData] = useState({ ...initialFormState });
const handleChange = ({ target }) => {
setContactData({
...contactData,
[target.name]: target.value,
});
};
const handleSubmit = (e) => {
e.preventDefault();
emailjs
.sendForm(
"emailjs_demo",
"demo_template",
e.target,
"user_demoblahblahblah",
)
.then(
(result) => {
console.log(result.text);
},
(error) => {
console.log(error.text);
},
);
//reset the form after submission
setContactData({ ...initialFormState });
};
return (
<div className="row m-5">
<div className="col-md-6 col-md">
<h2>Contact</h2>
<p>I would love to connect. Send me an email!</p>
<form onSubmit={handleSubmit}>
<div className="row">
<div className="col-sm-6 form-group">
<label htmlFor="name">Name:</label>
<input
type="text"
className="form-control"
name="name"
value={contactData.name}
onChange={handleChange}
required
/>
</div>
<div className="col-sm-6 form-group">
<label htmlFor="email">Email:</label>
<input
type="email"
className="form-control"
name="email"
value={contactData.email}
onChange={handleChange}
required
/>
</div>
</div>
<div className="row">
<div className="col-sm-12">
<label htmlFor="message">Message:</label>
<textarea
className="form-control"
type="text"
name="message"
maxLength="6000"
rows="7"
value={contactData.message}
onChange={handleChange}
required
></textarea>
</div>
</div>
<div className="row mt-2">
<div className="col-sm-12 form-group">
<button type="submit" className="btn btn-primary">
Send
</button>
</div>
</div>
</form>
</div>
</div>
);
}
export default Contact;
Be sure to make a test email to see if it works! It should be sent directly to your inbox and look something like this:
