Instantly Ai Rate Limits

Instantly's published API rate limits. The global limits are workspace-wide — they are shared between API v1 and API v2 and across every API key in the workspace, so adding keys does not add headroom. A handful of endpoints carry their own, much lower limits. This file replaces the scaffold defaults written on 2026-05-22, which were invented placeholders (10/min free, 120/min pro) and did not match anything Instantly publishes.

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

It captures 7 rate-limit definitions, measuring requests_per_second, requests_per_minute, and requests_per_30_days.

The profile also includes response codes documented for throttled, quotaExceeded, and upstreamThrottled.

Tagged areas include Cold Email, Outbound, Sales, Deliverability, and Rate Limiting.
