Email throttling refers to the practice of controlling the rate at which emails are sent or received by a mail server. This is essential to prevent server overload, ensure fair usage of resources, and mitigate the risk of being flagged as spam by receiving servers. Essentially, it regulates the flow of emails to maintain performance and deliverability.
For example, if a company sends a bulk email campaign to thousands of recipients all at once, the mail server can become overwhelmed, leading to delays in sending, potential blacklisting, or other mail delivery issues. By implementing throttling, the system can send a limited number of emails per minute or hour, thereby managing server load and enhancing the chances of successful delivery.
Throttle settings might be adjusted during high-traffic periods or when there's a known issue with server capacity. It can also be beneficial when sending to a list where recipient mail servers may impose rate limits themselves, ensuring smooth flow and reducing the chances of server blocks. Overall, email throttling helps maintain a balance between efficiency and reliability in email communications.
