How to Send Emails on User Sign-Up with Node.js, Express.js & cPanel

[Lomanu4]

Great! You're using Node.js and Express.js, and your website is hosted on a cPanel server. You want to send an email at sign-up time.

Here’s how you can do it step by step:

Step-by-Step: Send Email After Signup (Node.js + Express + cPanel)

? 1. Install nodemailer


Run this in your project folder:


npm install nodemailer
? 2. Create an Email Account in cPanel

1. Go to your cPanel.
2. Click on Email Accounts.
3. Create an email (e.g. no-reply@yourdomain.com).
4. Go to Connect Devices or Configure Email Client to get SMTP details.

For example:

Setting	Value
SMTP Host	mail.yourdomain.com
SMTP Port	465 or 587
Username	no-reply@yourdomain.com
Password	(your email password)
Encryption	SSL (for port 465) or TLS (587)

?‍? 3. Send Email in Signup Route


Here’s a sample Express route that sends an email:


const express = require("express");
const nodemailer = require("nodemailer");
const router = express.Router();

router.post("/signup", async (req, res) => {
const { email, name } = req.body;

// 1. Send the email
const transporter = nodemailer.createTransport({
host: "mail.yourdomain.com",
port: 465, // or 587
secure: true, // true for port 465, false for 587
auth: {
user: "no-reply@yourdomain.com",
pass: "your_email_password",
},
});

const mailOptions = {
from: '"Your Website" <no-reply@yourdomain.com>',
to: email,
subject: "Welcome to Our Site!",
html: `<p>Hi ${name},</p><p>Thanks for signing up!</p>`,
};

try {
await transporter.sendMail(mailOptions);
res.status(200).json({ message: "Signup successful. Email sent!" });
} catch (error) {
console.error("Email error:", error);
res.status(500).json({ error: "Signup successful but email failed." });
}
});

module.exports = router;
? 4. Test Your API


Make a POST request to /signup with body:


{
"email": "user@example.com",
"name": "John Doe"
}

Use Postman or your frontend form.

Optional but Recommended

• Make sure your domain's DNS records include proper SPF, DKIM, and DMARC (cPanel > Email Deliverability).
• Avoid using @gmail.com as sender; always use your domain email like no-reply@yourdomain.com.
