Pay only for what you use. There is no minimum fee.
If you are an Amazon EC2 user, you can get started with Amazon SES for free. You can send 2,000 messages for free each day when you call Amazon SES from an Amazon EC2 instance directly or through AWS Elastic Beanstalk. Many applications are able to operate entirely within this free tier limit, and it does not expire after a year.
Note: Data transfer fees still apply. For new AWS customers eligible for the AWS free usage tier, you receive 15 GB of data transfer out aggregated across all AWS services, which should cover your Amazon SES data transfer costs. In addition, all AWS customers receive 1GB of free data transfer per month.
