Verdicts

Courier

Free for 10,000 sends a month, then $0.005 a send with no platform fee. 170 MCP tools with no toolsets, filtering or read-only mode.

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

Courier

  1. Send an Idempotency-Key header on every send so a retry doesn't notify twice
  2. Set routing.method to single to stop at the first channel that works
  3. Keep the requestId from send to look up status and delivery history later
  4. Use a dedicated API key for the MCP server. Every one of the 170 tools runs with that key's full rights
  5. Space resends at least 2 seconds apart per message or you get a 429

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
