Amazon SNS plans
| Plan | Price | What it covers |
|---|---|---|
| Free Tier (permanent) | $0 | 1M mobile push notifications/month, 1M API requests, first 1,000 emails, first 100 US SMS, 100,000 HTTP/HTTPS deliveries |
| Mobile Push Notifications | $0.50 / 1M | Charged after the 1M/month free tier; same rate across regions |
| API Requests (Standard topics) | $0.50 / 1M | Each 64KB of published data billed as one request (256KB = 4 requests) |
| HTTP/HTTPS Deliveries | $0.60 / 1M | First 100,000 deliveries free |
| Email/Email-JSON | $2.00 / 100,000 | First 1,000 notifications free |
| SMS (US) | $0.0025 / message | First 100 US messages free; global average ~$0.0075, plus carrier fees by country |
- 64KB-chunk billing means a 256KB message counts as four requests, inflating costs unexpectedly
Knock plans
| Plan | Price | What it covers |
|---|---|---|
| Developer | $0/month | 10,000 messages/month, 500 guide active users, 500 AI agent credits, unlimited workflows/broadcasts/channels/team members, batch & delay, multi-tenancy, Google SSO. |
| Starter | $250/month | 50,000 messages/month ($0.005 per additional), 2,500 guide active users, 2,000 AI agent credits; removes Knock branding; adds email client previews. |
| Enterprise | Contact sales | Volume-based/annual-commit pricing; per-customer branding & preferences, i18n, data-warehouse analytics, Datadog, SCIM, SAML 2.0 SSO, HIPAA/BAA, enterprise SLAs, shared Slack support. |
- Steep price jump from free to the $250/month Starter plan can be hard to justify for small workloads
- Key enterprise features (per-customer branding, i18n, SCIM, SAML, HIPAA/BAA, data-warehouse analytics) are locked behind Contact-sales Enterprise pricing
- Review base is still relatively small, so the 4.6 G2 rating rests on early-adopter feedback
