Emailoctopus Rate Limits

EmailOctopus publishes its v2 rate limit precisely. Verbatim from the API reference: "Requests to the API are subject to a rate limit, which is implemented using the token bucket algorithm. Each request consumes one token and your bucket holds up to 100 tokens. Tokens are replenished at a rate of 10 per second." That is a sustained 10 requests per second with a burst of 100. Exceeding it returns HTTP 429 (too-many-requests); the knowledge base adds that the connection is blocked "for up to a minute". Separately, plan-level subscriber and monthly-send caps apply and surface as a 422 out-of-limits error rather than a 429.

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

It captures 5 rate-limit definitions, measuring requests, emails, subscribers, and records.

Limit state is signalled in the X-RateLimiting-Remaining and X-RateLimit-Retry-After response headers, and an exhausted limit returns HTTP 429.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled and quota_exceeded.

Tagged areas include Email, Email Marketing, Newsletters, Campaigns, and Automation.

Policies

Token Bucket
One token per request; bucket of 100; refill 10/second. Enables a steady 10 rps or an occasional burst of 100.
Blocking Window
Exceeding the limit returns 429 and blocks the connection for up to one minute (knowledge base, article 91).
Backoff Strategy
Honour 429 responses, read X-RateLimit-Retry-After, and retry with exponential backoff.
Bulk Work Exemption
EmailOctopus states that the dashboard import process is faster than the API for bulk contact loading and is not subject to these limits, and recommends webhooks over polling for change sync.
Plan-Based Limits
Sending and subscriber limits are determined by the account's plan tier.
