Constant Contact Rate Limits

Published Constant Contact V3 API rate limits, read from the provider's own rate-limits guide on 2026-08-13. Two application-wide ceilings apply — a per-second throttle and a daily quota — plus a third, resource-specific cap on queued bulk activities that is documented only in the OpenAPI. All three surface as HTTP 429 and are distinguishable ONLY by the error_key value in the response body.

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

It captures 3 rate-limit definitions, measuring requests_per_second, requests_per_day, and queued_activities.

The profile also includes response codes documented for throttled and quota_exceeded.

Tagged areas include Rate Limiting and Email.
