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 (matching is 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.

Matching is case-insensitive and ignores spaces and other special characters. Provider aliases (for example "Google Mail", "Outlook"), known provider domains, and even full email addresses (for example "user@googlemail.com") also resolve to a preset.

info

Most major email providers now require OAuth 2.0 authentication or app-specific passwords for security. The service presets only configure connection settings (and, for a few providers, the preferred SMTP AUTH mechanism). 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.

List of built-in services​

The Secure column shows whether the preset opens a TLS connection immediately (secure: true) or starts in cleartext and upgrades with STARTTLS. Preset extras lists any additional option the preset sets beyond host, port, and secure. A host or port shown as default is not part of the preset, so Nodemailer falls back to its normal default (localhost, and port 587 or 465 depending on secure).
