Plunk · Rate Limits

Plunk Rate Limits

The Plunk hosted API enforces a project-level rate limit of approximately 1,000 requests per minute. Email sending is additionally throttled per project and bulk operations (such as large campaign sends) are automatically queued rather than rejected. Requests that exceed the limit return HTTP 429. Self-hosted deployments can configure their own limits.

Plunk Rate Limits is the machine-readable rate-limit profile for Plunk on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests, emails, and jobs.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, throttledCode, billingCapped, and billingCappedCodes.

Tagged areas include Email, Transactional Email, Marketing, Automation, and Open Source.

Policies

Queuing

Backoff Strategy
Clients should implement exponential backoff with jitter and honor 429 responses.
Self-Hosted Configuration
Self-hosted deployments can configure their own rate limits and sending throughput.
