Standard topics take no idempotency token, so a retried `Publish` can send twice. SNS has no user preferences, digests or in-app channel, email is plain text to confirmed subscribers, and SMS starts in a sandbox.\n\n**Novu.** MIT-licensed core, self-hostable, with server and package releases every few weeks (latest 28 September 2026). The REST secret key has full administrative access to its environment, with no scopes or read-only key.\n\n## Before you call either\n\n### Amazon SNS\n\n1. Sign requests with SigV4 for service `sns` at `sns.\u003cregion\u003e.amazonaws.com`, or call `aws sns publish --topic-arn \u003carn\u003e --message \u003ctext\u003e` from the AWS CLI\n2. Track `MessageId` yourself on standard topics, because a retried `Publish` sends again. Use a FIFO topic with `MessageDeduplicationId` when duplicates matter\n3. Send per-channel text by setting `MessageStructure` to `json` and passing a JSON string with a `default` key plus keys such as `APNS`, `GCM`, `email` and `sms`\n4. Check `GetSMSSandboxAccountStatus` and the monthly spend quota before texting. Sandbox sends reach only verified numbers\n5. Expect an email subscription to stay in `PendingConfirmation` until the recipient clicks the link, and keep each email subscription under 10 messages a second\n\n### Novu\n\n1. Send `Authorization: ApiKey \u003ckey\u003e` to the REST API. Bearer is for the MCP server\n2. Ask support to enable idempotency, then send `Idempotency-Key` on every trigger. A 409 means the first call is still running\n3. Use eu.api.novu.co and eu.mcp.novu.co for an EU account. A US key won't authenticate there\n4. Pass `environmentId` from `get_environments` on MCP calls. OAuth sessions default to Development\n5. Keep `limit` at 100 or below on list calls. Higher values return 422\n\n## Questions\n\n### Which is better for AI agents, Amazon SNS or Novu?\n\nAmazon SNS scores 72.8 (BB) on agent readiness against Novu's 64.2 (B), and leads in 2 of 7 scored categories. Novu leads on reliability, schema \u0026 documentation, agent ergonomics, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Amazon SNS and Novu need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Amazon SNS and Novu without installing anything?\n\nYes. Amazon SNS has a hosted endpoint at https://sns.us-east-1.amazonaws.com and Novu at https://api.novu.co/v1.\n\n### Are Amazon SNS and Novu open source?\n\nNo open-source release is listed for Amazon SNS.
