Well-Known Services

Nodemailer includes built-in connection presets for many popular email providers. Instead of manually looking up each provider's SMTP server hostname, port number, and security settings, you can simply specify a service name when creating a transport. Nodemailer automatically configures all the connection details for you.

const nodemailer = require("nodemailer");

const transporter = nodemailer.createTransport({
  service: "Gmail", // Use any Service ID from the table below (case-insensitive)
  auth: {
    user: process.env.SMTP_USER,
    pass: process.env.SMTP_PASS,
  },
});

The service option is simply a convenient shortcut. You can always specify host, port, secure, and other connection options manually if you prefer. If your provider is not listed or if connection settings have changed, you have two options: submit a pull request to update the services.json file, or bypass the presets entirely and configure the connection details yourself.

info

Most major email providers now require OAuth 2.0 authentication or app-specific passwords for security. The service presets only configure the server connection settings. You are still responsible for setting up the correct authentication method for your provider. For Gmail-specific setup instructions, see Using Gmail.

AWS SES Users

While the SES service presets below use SMTP credentials, Nodemailer also offers a dedicated SES transport that integrates directly with the AWS SDK. The SES transport can be simpler to configure if you are already using AWS credentials in your application.
