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.
Pushover
One POST with three required fields, form or JSON. Recipients need the app, $4.99 per platform after a 30-day trial.
Before you call either
Amazon SNS
- Sign requests with SigV4 for service
snsatsns.<region>.amazonaws.com, or callaws sns publish --topic-arn <arn> --message <text>from the AWS CLI - Track
MessageIdyourself on standard topics, because a retriedPublishsends again. Use a FIFO topic withMessageDeduplicationIdwhen duplicates matter - Send per-channel text by setting
MessageStructuretojsonand passing a JSON string with adefaultkey plus keys such asAPNS,GCM,emailandsms - Check
GetSMSSandboxAccountStatusand the monthly spend quota before texting. Sandbox sends reach only verified numbers - Expect an email subscription to stay in
PendingConfirmationuntil the recipient clicks the link, and keep each email subscription under 10 messages a second
Pushover
- Use priority 2 with
retry(30 or more) andexpire(10,800 or less) when a person must act, then poll the receipt - Don't retry a 4xx. Fix the parameter named in
errors. Wait at least 5 seconds before retrying a 5xx - Read
X-Limit-App-Remainingbefore a batch. Over the monthly quota every send returns 429 - Keep messages to 1,024 characters and titles to 250
- Send to a group key to reach several people in one call. Each person still counts against the quota
