Strengths and weaknesses
Amazon SNS- +Very low cost: mobile push at $0.50 per million with a permanent 1M/month free tier, cheaper than most dedicated push vendors
- +Deep native integration with the AWS stack (Lambda, SQS, CloudWatch, IAM, Kinesis Firehose, EventBridge)
- +Massive fanout scale: up to 12.5M subscriptions per topic and 100,000 topics per account
- –No message persistence or history, you cannot inspect, store, or replay sent notifications
- –No built-in analytics, audience segmentation, A/B testing, scheduling, or rich notification UI (AWS steers you to Pinpoint for these)
- –Hard throughput (messages/second) and 256KB message-size limits
- +Single unified API and template designer covers push, email, SMS, in-app inbox, and chat, no per-provider integrations to maintain
- +Routes to ~11 push providers (APNS, FCM, Expo, OneSignal, Airship, Pusher Beams, etc.) so teams aren't locked to one push vendor
- +Native iOS, Android, React Native, and Flutter SDKs auto-manage device tokens and delivery/click tracking
- –Per-send pricing across all channels can be costlier than a single-purpose push vendor at very high volume
- –Handlebars-based templating has a learning curve some small teams find awkward
- –Some users report platform slowness during peak usage
