Well-Known Services
Nodemailer ships with connection presets for many popular SMTP providers.
Instead of looking up each provider’s SMTP host name, port and security settings
you can pass a single service string when you create a transport.
Nodemailer will fill in the rest for you.
const nodemailer = require("nodemailer");
const transporter = nodemailer.createTransport({
service: "Gmail", // any id from the table below, case insensitive
auth: {
user: process.env.SMTP_USER,
pass: process.env.SMTP_PASS,
},
});
Internally service is just a shortcut – you can always supply host, port,
secure and other options yourself. If something changes or your provider is
missing you can open a pull‑request against the services.json file
or bypass this feature entirely and set the connection details manually.
info
Most major providers require OAuth 2 or application‑specific passwords. The presets only configure the server connection; you are still responsible for using the correct authentication mechanism.
