Amazon SES

Amazon SES exposes a standard SMTP interface. Use the @betternotify/smtp transport with your SES SMTP credentials — no separate package needed.

Setup

1. Create SMTP credentials in the AWS console (IAM user with ses:SendRawEmail permission).
2. Note your regional SMTP endpoint (e.g. email-smtp.us-east-1.amazonaws.com).
3. Wire the SMTP transport:

import { smtpTransport } from '@betternotify/smtp';

const transport = smtpTransport({
  host: 'email-smtp.us-east-1.amazonaws.com',
  port: 587,
  auth: {
    user: process.env.SES_SMTP_USER!,
    pass: process.env.SES_SMTP_PASS!,
  },
});

For implicit TLS on port 465, set secure: true.

Why SMTP over the SDK

• Zero extra dependency — no @aws-sdk/client-sesv2 in your bundle.
• Works in any runtime with a TCP socket (Node.js, Bun).
• Same sending limits and deliverability as the SES v2 API.
• SMTP credentials are scoped to ses:SendRawEmail, reducing the blast radius compared to full SDK credentials.

Webhook events

SES delivers bounce, complaint, and delivery notifications via SNS. The webhook router will support SES SNS payloads in a future release — no separate adapter package required.
