Why does this limit matter?
A steady 100-email daily plan would exceed the monthly allowance before every month ends.
This value is scoped to Free; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Track both daily and billing-month sends rather than only the monthly total.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- Paid plans remove the daily cap but keep plan and overage controls.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
