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**Pushover.** One POST with three required fields, form or JSON. Recipients need the app, $4.99 per platform after a 30-day trial.\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### Pushover\n\n1. Use priority 2 with `retry` (30 or more) and `expire` (10,800 or less) when a person must act, then poll the receipt\n2. Don't retry a 4xx. Fix the parameter named in `errors`. Wait at least 5 seconds before retrying a 5xx\n3. Read `X-Limit-App-Remaining` before a batch. Over the monthly quota every send returns 429\n4. Keep messages to 1,024 characters and titles to 250\n5. Send to a group key to reach several people in one call. Each person still counts against the quota\n\n## Questions\n\n### Which is better for AI agents, Amazon SNS or Pushover?\n\nAmazon SNS scores 72.8 (BB) on agent readiness against Pushover's 53.1 (D), and leads in 6 of 7 scored categories.\n\n### Do Amazon SNS and Pushover need an API key?\n\nAmazon SNS takes an API key or an OAuth sign-in. Pushover needs an API key.\n\n### Can an agent call Amazon SNS and Pushover without installing anything?\n\nYes.
