To send e-mails in a production environment, use services like Sendgrid.

Verify the e-mail address on the Sender Management page and create the SendGrid API key on the API keys page.

import nodemailer from 'nodemailer';
(async () => {
const emailConfiguration = {
auth: {
user: process.env.EMAIL_USERNAME, // 'apikey'
pass: process.env.EMAIL_PASSWORD
host: process.env.EMAIL_HOST, // 'smtp.sendgrid.net'
port: process.env.EMAIL_PORT, // 465
secure: process.env.EMAIL_SECURE, // true
const transport = nodemailer.createTransport(emailConfiguration);
const info = await transport.sendMail({
from: '"Sender" <sender@example.com>',
to: 'recipient1@example.com, recipient2@example.com',
subject: 'Subject',
text: 'Text',
html: '<b>Text</b>'
console.log('Message sent: %s', info.messageId);
