Amazon SES pricing and its charges are based on the total emails sent out from your AWS account each month. Amazon will not charge you anything for the first 3,000 emails you send for that month up to 1 year. If you exceed the defined number of emails, then you’ll have to pay them $0.10 for every additional 1,000 emails you send from your AWS Account. Also, you need to add your Billing card while creating a new AWS Account. This is Amazon SES free tier limit, which is 3,000 emails free per month, so try to stay within the limit if you want to try it out for free.
