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
- +Completely free with no per-message charge and no message-count limit, even at large scale
- +Native, default push channel for Android via Google Play Services plus broad iOS and web support
- +Three flexible targeting modes: individual token, device group, and topic subscription with boolean conditions
- –No published SLA or delivery-latency guarantee; delivery is explicitly best-effort
- –Reported delayed or dropped notifications, especially on iOS and battery-optimized/Doze Android devices
- –Console and notification dashboard are limited, with no built-in segmentation or lifecycle/journey tooling
