As an Amazon SES customer, you don't need to build your own email solution from the ground up, or incur the costs of licensing, installing and operating third-party software. Instead, you can start sending messages in minutes using the AWS software development kits for Java and .NET, or code directly to our HTTPS interface using your favorite programming language.
Amazon is able to pass on the efficiencies of its scale to customers, and pricing for Amazon SES is only $0.10 per thousand email messages sent. Additionally, a customer can send 2,000 email messages for free each day when these emails originate from Amazon EC2 or AWS Elastic Beanstalk.
Pricing seems pretty cool.
