Understanding NDR: How Long Does Information Stay on the NDR?

Emails are an essential mode of communication for businesses today. However, not all emails reach their intended recipient, and the ones that do not make it to the recipient’s mailbox often end up in the NDR. NDR stands for Non-Delivery Report, and it is an automated email that informs the sender that their email could not be delivered. But, have you ever wondered how long the information stays on the NDR? In this article, we will explore the concept of NDRs and understand how long the information stays on them.

What is an NDR?

An NDR or Non-Delivery Report is an automated email generated by the mail server when an email could not be delivered to the intended recipient. The NDR contains information about the original email, such as the sender, recipient, subject, and reason for the non-delivery.

The NDR is useful for both the sender and the recipient as it helps determine whether there is an error in the email address or whether the email server is down. The NDR also helps prevent email spam as it informs the sender that their email could not be delivered.

How Long Does Information Stay on the NDR?

The information on the NDR is usually stored on the mail server until it is cleared by the administrator. However, the amount of time the information stays on the NDR varies depending on the mail server’s settings.

For most mail servers, the default retention period of NDRs is 7 days. After 7 days, the NDR is automatically deleted from the mail server.

However, some mail servers allow administrators to change the retention period of NDRs. In some cases, NDRs may be saved for up to 30 days, depending on the mail server’s settings.

It’s important to note that the retention period of NDRs is different from that of emails. When an email is not delivered, it is stored on the mail server for a specified period before it is deleted. The email’s retention period depends on the settings of the mail server and can vary from a few days to several months.

Conclusion

In conclusion, NDRs are essential in ensuring the smooth functioning of email communication for businesses. They provide useful information to both the sender and recipient and help prevent email spam. While the retention period of NDRs varies depending on the mail server’s settings, the default retention period is usually 7 days. It’s important to understand the concept of NDRs to effectively manage your email communication and ensure your emails reach their intended recipient.
