Rate limiting

Rate limiting is a technique to restrict traffic on a server. In email terms, rate limiting in Application Program Interfaces (APIs) refers to how an email API might limit the number of calls an organization can make during a set period, impacting the number of emails they can send during that time frame. Rate limiting is a way to ensure fair use and is also an excellent way to protect infrastructure from hackers who might spam an open API endpoint on a brand’s website with too many requests. Organizations typically rate limit web app APIs to secure their websites from cyber attacks and manage overall network traffic.
