Paubox Rate Limits

Paubox publishes hard sending limits (recipients, attachment size, batch size) and plan quotas with overage pricing, but does NOT publish a numeric request rate limit and does NOT document any rate-limit response header. An agent gets no runtime pacing signal — only the 429 itself.

Paubox Rate Limits is the machine-readable rate-limit profile for Paubox on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions.

Limit state is signalled in the documented, ratelimit_headers, retry_after, and note response headers.

Tagged areas include Email, HIPAA, Healthcare, Compliance, and Transactional Email.
