 ## Best Practices
 
 ### Rate Limits
-Customer.io has limits on the data collected by their API. To ensure your events arrive in Customer.io, make sure that you're respecting the limits placed on the [Customer.io API](https://customer.io/docs/api/#tag/trackLimit){:target="_blank"}. If you're using Segment's [HTTP API](/docs/connections/sources/catalog/libraries/server/http/) to send a batch of events to Customer.io at once, make sure you throttle the `import` to 100-200 requests per second.
+Customer.io's [Track API](https://docs.customer.io/integrations/api/track/#tag/trackLimit){:target="_blank"} has a rate limit of 1000 requests per second. It's not strictly enforced, but consistently exceeding it may lead to throttling, especially during periods of high system load. If Customer.io detects a sustained high volume that could impact other customers, they may contact you to help adjust your integration.
