Verdicts

OneSignal

Runs push delivery itself, so there's no separate push provider to wire up. Three incidents on the API and SDK endpoints in September 2026.

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

OneSignal

  1. Use Authorization: Key <key>, not Bearer, and put app_id in the body
  2. Send an idempotency_key UUID with every create call and reuse it on each retry
  3. On 429, wait for Retry-After, then back off with jitter, up to 10 attempts
  4. Stay under 10 sends per subscribed subscription in 15 minutes or the app is disabled
  5. Target people with include_aliases.external_id and set target_channel

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
