Boosting Email Delivery Performance with Nodemailer and AWS SES in Node.js

Introduction: In today’s digital landscape, effective email communication is crucial for businesses and individuals alike. Whether it’s sending notifications, newsletters, or transactional emails, ensuring reliable and optimized email delivery is paramount.

import { createTransport, Transporter } from 'nodemailer';
import { SES } from 'aws-sdk';

const SENDING_RATE = 5;
const MAX_CONNECTIONS = 1;

const configureAWS = (): void => {
 // Set your AWS credentials
 const credentials = {
 accessKeyId: process.env.AWS_ACCESS_KEY_ID,
 secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
 };
// Set your AWS region
 const region = process.env.AWS_REGION;
// Configure AWS SDK
 SES.config.update({ credentials, region });
};

const createSESTransporter = (): Transporter => {
 // Configure the SES transporter
 const transporterOptions = {
 SES: new SES(),
 sendingRate: SENDING_RATE,
 maxConnections: MAX_CONNECTIONS,
 };
 return createTransport(transporterOptions);
};

configureAWS();
const sesTransporter: Transporter = createSESTransporter();

export { sesTransporter };
