N/email Module in NetSuite: Complete Guide to Sending Emails

The N/email module lets SuiteScript send emails programmatically — from simple notifications to bulk campaigns with attachments and record associations.

Sending a Simple Email

define(["N/email"], (email) => {
  email.send({
    author: 12345,
    recipients: ["user@company.com"],
    subject: "Order Confirmed",
    body: "Your order has been confirmed.",
    relatedRecords: { transactionId: 67890 }
  });
  return {};
});

Sending with Attachments

const pdfFile = render.transaction({ entityId: 123, printMode: render.PrintMode.PDF });
email.send({
  author: employeeId,
  recipients: [customerId],
  subject: "Your Invoice",
  body: "Please find your invoice attached.",
  attachments: [pdfFile]
});
