From a front end client you can send a request to an SMTP server, which will send the email.

This tutorial runs over how to do that with the emailJS SMTP server, (which allows you to send 200 free emails/month in case free is a priority).

I'll summarize because they didn't cover everything I wanted.

Step1: Install emailJS

Install emailJS via

npm install emailjs-com

or

yarn add emailjs-com

Source

If you are using create-react-app please view the tutorial I mentioned above or this linked source, where they provide instructions on how to include emailJS with create-react-app

Step 2: Create a form to send the email

This is a code example of a form which sends an email using emailJS, You must replace 'YOUR_SERVICE_ID', 'YOUR_TEMPLATE_ID', and 'YOUR_USER_ID' with your actual id's(which I will explain where to find in later steps)

import React from 'react';
import emailjs from 'emailjs-com';

export default function ContactUs() {

  function sendEmail(e) {
    e.preventDefault();    //This is important, i'm not sure why, but the email won't send without it

    emailjs.sendForm('YOUR_SERVICE_ID', 'YOUR_TEMPLATE_ID', e.target, 'YOUR_USER_ID')
      .then((result) => {
          window.location.reload()  //This is if you still want the page to reload (since e.preventDefault() cancelled that behavior) 
      }, (error) => {
          console.log(error.text);
      });
  }

  return (
    <form className="contact-form" onSubmit={sendEmail}>
      <input type="hidden" name="contact_number" />
      <label>Name</label>
      <input type="text" name="from_name" />
      <label>Email</label>
      <input type="email" name="from_email" />
      <label>Subject</label>
      <input type="text" name="subject" />
      <label>Message</label>
      <textarea name="html_message" />
      <input type="submit" value="Send" />
    </form>
  );
}

Source (I made some adjustments)

  • If you don't want your api details to be visible from the client, you would have to make a request (containing the email message, from, to, etc.) to a backend server(which would be set up and running to receive requests) via something like axios or fetch and then execute the sendEmail function from your server

Step 3: Create an emailJS account

Set up an account at https://www.emailjs.com/

Step 4: Connect an email account to emailJS and get YOUR_SERVICE_ID

Connect an email by adding a service, in this case I used gmail.

'YOUR_SERVICE_ID'(step 2) should be the id beside Service ID

enter image description here

Step 5: Create a template email message and get YOUR_TEMPLATE_ID

Create a a template by clicking Email Templates in the side nav and selecting create new template. This will create an email outline and give you a template id

You should replace 'YOUR_TEMPLATE_ID'(step 2) with this template id

enter image description here

Here is an example Email template

enter image description here

Step 6: Get YOUR_USER_ID

You can find your userID by going to Integration -> API

Replace 'YOUR_USER_ID'(step 2) with the id under API Keys -> Public Key

enter image description here

  • If you don't want spam emails, add Captcha
  • if you change your email password, you have to redo step 4

From frontend only you can trigger mails using an smtp server such as smtpJS

Steps to follow is

  1. Go to this link smtpJS
  2. Click GetSMTPCredentials and register.
  3. After registering, note down the credentials and click ENCRYPTSMTPCrendentials

A sample would be as follows

var test={
sendEmail(subject,to,body){
    
    /* SmtpJS.com - v3.0.0 */
    let Email = { send: function (a) { return new Promise(function (n, e) { a.nocache = Math.floor(1e6 * Math.random() + 1), a.Action = "Send"; var t = JSON.stringify(a); Email.ajaxPost("https://smtpjs.com/v3/smtpjs.aspx?", t, function (e) { n(e) }) }) }, ajaxPost: function (e, n, t) { var a = Email.createCORSRequest("POST", e); a.setRequestHeader("Content-type", "application/x-www-form-urlencoded"), a.onload = function () { var e = a.responseText; null != t && t(e) }, a.send(n) }, ajax: function (e, n) { var t = Email.createCORSRequest("GET", e); t.onload = function () { var e = t.responseText; null != n && n(e) }, t.send() }, createCORSRequest: function (e, n) { var t = new XMLHttpRequest; return "withCredentials" in t ? t.open(e, n, !0) : "undefined" != typeof XDomainRequest ? (t = new XDomainRequest).open(e, n) : t = null, t } };

    Email.send({
        SecureToken : process.env.SECURE_TOKEN, // write your secure token
        To : to, // to include multiple emails you need to mention an array
        From : process.env.EMAIL_HOST,
        Subject : subject,
        Body : body
    })
    .then(message=>{
        // alert(message);
    });

    
}
}

 export default test;

you can import above js file like below and call the method

import test from '../../components/sendEmail'
test.sendEmail("sub","msg");

React is only used for front end purpose so it is not only enough to send email.

But you can send email from client usingsome external API, like Mailjet, Gmail Api etc
