Amazon SNS pricing

Amazon Simple Notification Service (Amazon SNS) Standard topic pricing is based on the number of monthly API requests made, and the number of deliveries to various endpoints (the cost of the delivery depends on the endpoint type). 

Note: Each 64KB chunk of published data is billed as 1 request. For example, a single publish with a 256KB payload is billed as four requests.

Note: With the exception of SMS messages, each 64KB chunk of delivered data is billed as 1 delivery. For example, a single notification with a 256KB payload is billed as four deliveries.

Amazon SNS FIFO topic pricing is based on the number of published messages, the number of subscribed messages, and their respective amount of payload data.

Subscription messages are calculated by multiplying the number of published messages and the number of subscriptions. Both filtered and delivered messages count towards the number of subscription messages.

Note: Each message from 1KB to 256KB is billed as one message. Any message smaller than 1KB is rounded up to 1KB.

Data transfer “in” and “out” refers to the data transfer into and out of Amazon SNS. Data transferred into Amazon SNS is free of charge. Amazon SNS does not charge for per-message notification delivery when delivering messages to Amazon SQS and AWS Lambda, but does charge for the amount of data transferred from Amazon SNS to Amazon SQS or AWS Lambda, when messages are delivered. Data transferred from Amazon SNS to Amazon SQS or AWS Lambda is charged at Internet Data Transfer rates, as shown in the above table, whether the data transfer occurs within a single AWS region or across different AWS regions.

Data transferred between Amazon SNS and Amazon EC2 within a single region is free of charge (i.e., $0.00 per GB). Data transferred between Amazon SNS and Amazon EC2 in different regions will be charged at Internet Data Transfer rates on both sides of the transfer.

* Your free usage is calculated each month across all regions and automatically applied to your bill – free usage does not accumulate.
** As part of AWS’s Free Usage Tier, new AWS customers will receive free 15 GB of data transfer out each month aggregated across all AWS services for one year.
*** Data transfer out rate tiers aggregate outbound data transfer across Amazon EC2, AWS Lambda, Amazon EBS, Amazon S3, Amazon Glacier, Amazon RDS, Amazon SimpleDB, Amazon SQS, Amazon SNS, Amazon DynamoDB, AWS Storage Gateway, and Amazon VPC.

Amazon SNS message filtering pricing depends on the filtering method. Attribute-based message filtering is free, while payload-based message filtering is based on the total amount of outbound payload data scanned for each subscription with an active filter policy. Both filtered and delivered messages count towards the amount of outbound payload data scanned.

Note: Each outbound message scanned will be billed for a minimum of 1 KB of scanning.

Message archiving and replay pricing is based on the amount of data you store and the length of time the data is stored for.

Note: Any data that is archived will be billed for a minimum of 1 day of storage and message replay is billed at the existing FIFO API Requests and Payload data rates.

Note: Each message that is scanned and protected (blocked or de-identified) will be billed for a minimum of 1KB of message scanning.

Amazon SNS also offers scalable SMS (text) messaging to 200+ countries leveraging AWS End User Messaging. It has no upfront costs and you can pay as you go. With Amazon SNS, you can also mark your SMS messages as Transactional or Promotional based on the use case and content of your messages. To learn more about message types, visit the FAQs.

The price for sending SMS messages varies by destination country. In some cases, the price also includes a telecom carrier fee for the destination phone number. For some countries, to successfully send SMS messages, you are required to purchase and use dedicated origination identities. Starting November 1, 2024, charges for SMS services will appear under AWS End User Messaging on your AWS bill. There will be no changes to pricing as part of this change. To learn more about the price of sending SMS and the price of owning and operating with an origination identity, visit the Amazon SNS SMS pricing page.
