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
