Amazon SNS pricing is not a single number — it breaks down by delivery channel. Here is what SMS, push notifications, and email actually cost, and when SNS beats the alternatives.
SMS is the most complex SNS channel to price. Costs depend on the destination country, message type (transactional vs. promotional), and sender type (toll-free number, short code, or sender ID). For US domestic SMS, our tracked rate is $0.0065/SMS per outbound message — versus $0.0079/SMS on Twilio. SNS does not natively support inbound SMS, and two-way messaging is limited.
Rates shown for US domestic SMS from our tracked comparison data. Verify current pricing on AWS's official SNS pricing page before committing volume.
