You can make up to five requests per second to the EmailOctopus API. If exceeded, connection will be blocked. These limits help us to ensure a high-quality service for all users.

You can make up to 5 requests per second to our API. If you exceed this, you will receive a '429 Too Many Requests HTTP' status code and your connection will be blocked for up to a minute.

These limits help us to ensure a high-quality service for all users. If you're using our API to bulk upload a list, you will find our import process more performant as it is not subject to these limits.
