// Next.js App Router / Server Action (Send transactional email):
import nodemailer from "nodemailer";

const transporter = nodemailer.createTransport({

  auth: {
    user: process.env.PHOTON_USER,
    pass: process.env.PHOTON_PASS,
  },

export async function sendOtp(toEmail, otpCode) {
  return await transporter.sendMail({
