As AWS works with the concept of pay as you go, there is no initial cost but will be charged as you use service. Users pay $0.50 per 1 million Amazon SNS Requests, $0.06 per 100,000 notification deliveries over HTTP, and $2.00 per 100,000 notification deliveries over email. For SMS messaging, users can send 100 free notification deliveries, and for subsequent messages, charges vary by the destination country.
