API limits

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 10 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 find that you need to exceed these limits, consider the following:

• If you're using our API to bulk upload a list, you'll find the import process is faster as it's not subject to these limits.
• If you're using our API to sync changes to a list with your database, you'll find our webhooks feature to be more convenient.
