Rate limits, quotas and plans
How Publiq applies per-minute, hour, day and cycle limits — and what to do on a 429.
Each plan defines quotas — for example, emails per minute, hour, day and per billing cycle. When exceeded, the API responds 429 rate_limit_exceeded.
The SDK already does automatic retry with backoff on 429 and transient errors. If you call the API directly, implement retry with exponential backoff and respect the Retry-After header when present.
For large volumes, prefer Broadcasts and automations (which respect quotas for you) over firing thousands of emails.send in parallel.
