Reacher's new endpoint /v1/check_email, has a default rate limit of 60 requests per minute and 10,000 requests per day. These limits are configurable, as detailed in their documentation. However, we need to implement throttling on our end to prevent exceeding these limits, as requests beyond the threshold will either timeout or be marked as unverified.
