## Which one, for what

### Amazon SNS (BB)

Good for: Teams already on AWS that want cheap push, SMS and plain-text email alerts or fan-out to queues and functions under IAM and CloudTrail.

Ahead on:
- Reliability, 75 against 58
- Schema & documentation, 83 against 69
- Security & auth, 89 against 51
- Transparency & trust, 83 against 54

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: No idempotency token on `Publish` to a standard topic. Only FIFO topics deduplicate, over a five-minute window

### Pingram (C)

Good for: An agent that needs to send transactional email and SMS and read replies through one account without separate carrier or SMTP providers.

Ahead on:
- Payments & pricing, 40 against 35
- Maintenance & community, 81 against 75

Watch for: The terms of service forbid using the service for benchmarking. This matters before any probe is run

## Verdicts

**Amazon SNS.** IAM and topic policies limit a credential to single actions and topics, a read-only managed policy exists, and CloudTrail can log each publish. 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.

**Pingram.** Email and SMS go out through one REST call with built-in delivery, per-message prices are public and the free tier needs no card. No rate limits or idempotency keys were found in the reviewed documentation, and the MCP connector acts with the signed-in user's whole account.

## Before you call either

### Amazon SNS

1. Sign requests with SigV4 for service `sns` at `sns.<region>.amazonaws.com`, or call `aws sns publish --topic-arn <arn> --message <text>` from the AWS CLI
2. Track `MessageId` yourself on standard topics, because a retried `Publish` sends again. Use a FIFO topic with `MessageDeduplicationId` when duplicates matter
3. 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`
4. Check `GetSMSSandboxAccountStatus` and the monthly spend quota before texting. Sandbox sends reach only verified numbers
5. Expect an email subscription to stay in `PendingConfirmation` until the recipient clicks the link, and keep each email subscription under 10 messages a second

### Pingram

1. Use the API host for the account's region. The key and region (`us`, `eu` or `ca`) come from the API Keys page in the dashboard
2. Keep the `trackingId` from each send and check Logs before retrying. No idempotency key was found, so a blind retry can send twice
3. Pass `accountId` on MCP tools when the user belongs to several accounts. Without it the tools use the earliest account joined
4. Create broadcasts as drafts only. Pingram's own skill says a person must send a broadcast from the dashboard
5. Expect 402 when the monthly budget is spent. Unused balance does not roll over
