Email Nextjs

How to send mail using Nodemailer in NextJS

"use server";
import nodemailer from "nodemailer";

export default async function sendEmail(
  toEmail: string,
  subject: string,
  text: string
) {

  const password = process.env.EMAIL_PASSWORD;
  const host = process.env.EMAIL_HOST;
  const user = process.env.EMAIL_USERNAME;


  console.log(typeof process.env.EMAIL_PASSWORD);

  try {
    // Create a Nodemailer transporter with your email provider's settings
    const transporter = nodemailer.createTransport({
      port: 465,
      host: host,
      auth: {
        user: user,
        pass: password,
      },
    });

    // Send the email
    const info = await transporter.sendMail({
      from: "YourEmail@address.here",
      to: toEmail,
      subject: subject,
      text: text,
    });

    console.log("Message sent: %s", info.messageId);
  } catch (error) {
    console.error("Error sending email:", error);
  }
}

“use server” for NextJS to use this code in server.

.env file

EMAIL_USERNAME='add your email address here'
EMAIL_PASSWORD=your password
EMAIL_HOST='email host here'
EMAIL_SERVER_PORT=465

As sendEmail is a function exported, you can use it anywhere in your code.

This is a Nextjs app, so you might host it in Vercel.

I faced an error there:

Error sending email: Error: connect ECONNREFUSED 127.0.0.1:465 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1606:16) at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17) { errno: -111, code: 'ESOCKET', syscall: 'connect', address: '127.0.0.1', port: 465, command: 'CONN' }

This was solved by:

Changing the port from 465 to 587
