You can use nodemailer with gmail to send email in your nodejs app.

1. Follow [this article](https://www.lifewire.com/get-a-password-to-access-gmail-by-pop-imap-2-1171882) to create App-Specific password in Gmail. While following this article, just note that on step 2, it asks you to click on "Google Account". That name has been changed to "Manage your Google Account". 

By the end of the tutorial, you should have your app specific gmail password.

```
your_app_specific_gmail_password / your_name@gmail.com
```

2. Once you have got the password, its time to code. Install nodemailer from npm

```
npm i nodemailer
```

3. Let's create a reusable function in helpers folder. We need to pass req, res, emailData as arguments to this function.

```js
// /helpers/email.js
const nodeMailer = require("nodemailer");

exports.sendEmailWithNodemailer = (req, res, emailData) => {
 const transporter = nodeMailer.createTransport({
 host: "smtp.gmail.com",
 port: 587,
 secure: false,
 requireTLS: true,
 auth: {
 user: "your_name@gmail.com", // MAKE SURE THIS EMAIL IS YOUR GMAIL FOR WHICH YOU GENERATED APP PASSWORD
 pass: "your_app_specific_gmail_password", // MAKE SURE THIS PASSWORD IS YOUR GMAIL APP PASSWORD WHICH YOU GENERATED EARLIER
 },
 tls: {
 ciphers: "SSLv3",
 },
 });

 return transporter
 .sendMail(emailData)
 .then((info) => {
 console.log(`Message sent: ${info.response}`);
 return res.json({
 success: true,
 });
 })
 .catch((err) => console.log(`Problem sending email: ${err}`));
};
```

4. Now we can import it in any controllers and use to send emails. Lets try using it to send contact form.

```js
// controllers/form.js
const { sendEmailWithNodemailer } = require("../helpers/email");

exports.contactForm = (req, res) => {
 console.log(req.body);
 const { name, email, message } = req.body;

 const emailData = {
 from: "your_name@gmail.com", // MAKE SURE THIS EMAIL IS YOUR GMAIL FOR WHICH YOU GENERATED APP PASSWORD
 to: "your_name@gmail.com", // WHO SHOULD BE RECEIVING THIS EMAIL? IT SHOULD BE YOUR GMAIL
 subject: "Website Contact Form",
 text: `Email received from contact from \n Sender name: ${name} \n Sender email: ${email} \n Sender message: ${message}`,
 html: `
 <h4>Email received from contact form:</h4>
 Sender name: ${name}
 Sender email: ${email}
 Sender message: ${message}
 <hr />
 This email may contain sensitive information
 https://onemancode.com
 `,
 };

 sendEmailWithNodemailer(req, res, emailData);
};
```

5. Now check your inbox. A new email must be waiting for you. You will see the success or error message in server console too. If you do not see any emails, make sure to checkout spam folder too.
