Limiting the number of emails that one may simultaneously send to a particular Internet service provider (ISP) or distant server is known as “throttling.”
We have put together this article to help you better understand email throttling and what it means in 2023. Keep reading to find out!
If a single sender simultaneously transmits many messages, the Internet service provider (ISP) may mark those communications as spam and then ban them. Even though this looks to be some limitation, it comes with several beautiful chances for senders.

What exactly does “Email Throttling” mean?
Email throttling, as a concept, refers to the act of purposefully restricting the number of emails that you send via a server to a single Internet service provider (ISP) or a distant server throughout a certain amount of time.
Spreading out the transmission of your communications is necessary if you want to prevent having them banned by Internet service providers. This transmission is helpful in a variety of different ways. To begin, you can calculate the number of emails successfully sent during high-traffic times.
This aspect will allow you to improve the likelihood of receiving positive replies to your email marketing campaigns. The information gleaned from such sources may also be helpful when it comes to the configuration of future sends.
Additionally, when you throttle, you are allowed to regulate reactions properly. For instance, if you included a phone number as a call to action in your emails, throttling will provide you with enough time to effectively handle the traffic coming into your contact center. You will also have a better handle on the bandwidth used by your website’s server in the event of limited-time discounts and promotions.
The practice of throttling is disadvantageous for high-volume senders that place a premium on receiving the most significant possible response, given that one can only obtain positive responses via on-time delivery. The daily deal website is an example of the kind of website or online company that fits into this category. In a firm like this, the window of opportunity to make the most sales is often relatively small. Because of this, they need all of their email communications to be sent to subscribers as soon as possible. In these circumstances, the sender is responsible for ensuring a stellar reputation in terms of email delivery. When an Internet service provider (ISP) determines that a sender is a spammer, they make the criteria more stringent. Consequently, it is essential to adhere to the best practices. If you find it helpful, contact an experienced email provider to assist you in establishing and maintaining these standards.
Let us examine the throttling operation and its impact on sending emails.
What are the Reasons for Limiting Email Access?
Emails are said to be throttled if an Internet service provider (ISP) restricts the number of messages received from a particular sender within a given time frame. When the throttling is activated, any emails sent exceeding the limit will be immediately discarded. This process results in a significant increase in the number of bouncebacks. The term “deferral” may also be used interchangeably with “throttling” of email.
The length of the restriction is contingent upon the circumstances, although in most cases, it is only temporary. Error messages such as “User’s mailbox is above quota” or “User is getting mails too often at present, please try again later” are standard error messages linked with throttling. These 400 kinds of problems are typically deleted in 72 hours.
If the desired recipient does not get your email, it may be because their inbox is too full. It’s possible that this is happening because the server has all of its ports blocked, making it impossible to accept incoming emails. The third possible cause is that the server receiving your messages cannot recognize any of the IP addresses associated with your account. As a result, it treats your messages as spam. To prevent this from happening, you should constantly try to get to know your receivers better, so they are already acquainted with you.
It is standard practice for receivers to designate the sender as spam in their email client. The server will not prevent you from sending emails because of this. Still, it will prevent it from receiving additional emails until it learns how other potential recipients of the same email reacted.
If you want to avoid harming your sending reputation, you should appropriately manage email throttling.
How Can I Prevent the Limiting of My Email?
The problem of throttling may be avoided by the use of a few different solutions, including the following:
- You may spread out the sending of your emails over a more extended period by scheduling them.
- Organizing your emails into different folders based on their senders’ domains. You may also break your lists up into many sections by, for example, categorizing your marketing and transactional email into distinct groups. This aspect will allow you to deal with each reputation uniquely.
- Sending emails at earlier periods ensures that each recipient receives the email before the deadline for “completions.”
