Amazon Simple Email Service (Amazon SES) is a cost-effective, flexible, and scalable email service that enables developers to send mail from within any application. It is designed to help digital marketers and application developers send marketing, notification, and transactional emails. It is not intended to be used for face-to-face communication (like Amazon Chime) or as a customer contact center solution (like Amazon Connect). While SNS can send notifications, it is mostly used for sending messages to subscribing endpoints or clients, not specific for emails.
