What is EmailJS?

EmailJS is a powerful service that lets you send emails directly from your client-side JavaScript applications — without needing to build or maintain a backend email server. It connects your app to your email provider (Gmail, Outlook, custom SMTP, etc.) through an easy-to-use API, so your users can send emails (like contact forms, feedback, or order requests) right from the frontend.

Why use EmailJS?

Sending emails from frontend apps can be tricky because you usually need a backend server to handle email sending securely. EmailJS removes this hassle by providing:

• Direct client-side email sending via their JavaScript SDK.
• No backend infrastructure required.
• Easy integration with popular email services.
• Free tier suitable for many small projects and prototypes.
• Template-based emails and customizable parameters.

Setting up your EmailJS account

Follow these quick steps to get started:

1. Go to emailjs.com and sign up for a free account.
2. Connect your preferred email service (Gmail, Outlook, or SMTP server) in the EmailJS dashboard.
3. Create an email template you want to use for sending (e.g., contact form submission).
4. Note your Service ID, Template ID, and User ID — you'll need these in your app.

Install EmailJS SDK

Add EmailJS's JavaScript SDK to your React/Next.js project by running:

npm install @emailjs/browser
# or
yarn add @emailjs/browser

Example React/Next.js form code

Here's a simple React component demonstrating how to send an email using EmailJS from a contact form:

{`'use client';

import React, { useRef, useState } from 'react';
import emailjs from '@emailjs/browser';

export default function ContactForm() {
  const form = useRef();
  const [status, setStatus] = useState('');

  const sendEmail = (e) => {
    e.preventDefault();
    setStatus('Sending...');
    emailjs.sendForm(
      'YOUR_SERVICE_ID',      // replace with your EmailJS service ID
      'YOUR_TEMPLATE_ID',     // replace with your EmailJS template ID
      form.current,
      'YOUR_USER_ID'          // replace with your EmailJS user ID (public key)
    )
    .then((result) => {
      setStatus('Email sent successfully!');
      form.current.reset();
    }, (error) => {
      setStatus('Failed to send email. Please try again.');
      console.error(error.text);
    });
  };

  return (
    

      
        Name:
        
      
      

      
        Email:
        
      
      

      
        Message:
        
      
      

      
      
{status}
    
  );
}
`}

Important tips

• Keep your User ID private but it is safe to expose in frontend as EmailJS is designed for client-side usage.
• Use email templates in EmailJS dashboard to customize the email content and layout.
• Test your form thoroughly to ensure emails send as expected.
• Make sure to configure your email service properly (Gmail may require app passwords or OAuth).
• If you plan to deploy, add environment variables and avoid hardcoding your IDs directly in production.

What next?

Now that your app can send emails directly from the frontend, you can:

• Enhance the form with validation and UI feedback.
• Integrate with other services for notifications.
• Use EmailJS's advanced features like attachments, dynamic templates, and user authentication.
• Explore backend email options if you need more control or volume.
