About EmailJS
What is EmailJS?
EmailJS is a service that allows you to send emails directly from your frontend code — no server-side setup required. It keeps your email service credentials secure on its servers, so you can trigger emails safely from client-side JavaScript, React, Vue, or any other frontend app.
Who is it for?
EmailJS is ideal for developers and small teams building static sites, prototypes, or browser-based apps that need to send transactional emails (like contact forms, feedback submissions, or notifications) without maintaining a backend. It is not suitable for high-volume email marketing campaigns or sending bulk newsletters.
How does it work?
You connect your email service (Gmail, Outlook, SendGrid, Amazon SES, and others), create a reusable HTML or plain-text email template in the EmailJS dashboard, then add one of its SDKs to your code. A single call to emailjs.send() triggers the email. It supports attachments, dynamic variables, CC/BCC, and reCAPTCHA for spam protection.
Real use cases
Common uses include: contact forms on static websites, order confirmations in e-commerce frontends, password reset links in serverless apps, and automated notifications triggered by user actions.
