Benchmark Email Rate Limits
Benchmark Email publishes exact rate limits for BOTH of its APIs, and they are completely different numbers on completely different windows. The new v1 API runs an hourly limit plus a plan-derived monthly quota, signalled with five response headers. The classic v3.0 API runs a 2-minute burst limit plus a daily cap. Neither uses the IETF RateLimit header draft; both use X- prefixed headers, and both return 429 with Retry-After on exhaustion.
Benchmark Email Rate Limits is the machine-readable rate-limit profile for Benchmark Email on the APIs.io network, conforming to the API Commons Rate Limits specification.
Tagged areas include Email Marketing, Campaigns, Contacts, Automation, and Transactional Email.
