What is a DSN?
A
Delivery Status Notification (DSN), often referred to as a bounce message or Non-Delivery Report (NDR), is an automated email message sent by a mail server to notify the sender of delivery issues. In the context of
email marketing, understanding DSNs is crucial for managing and optimizing your campaigns.
Types of DSNs
There are primarily two types of DSNs: Soft Bounces: These are temporary issues such as a full inbox or a server being down. Soft bounces indicate that the email might be delivered successfully if retried.
Hard Bounces: These are permanent issues such as an invalid email address or a domain that no longer exists. Hard bounces indicate that the email will never be delivered to that address.
Why are DSNs Important in Email Marketing?
DSNs provide crucial feedback on the status of your email campaigns. They help you: Identify and remove
invalid email addresses from your list, improving deliverability.
Understand the reasons for email delivery failures, enabling you to address any underlying issues.
Maintain a good
sender reputation by reducing the number of undeliverable emails.
How to Handle DSNs
Efficiently managing DSNs can significantly improve your email marketing success. Here are some strategies: Monitor bounce rates: Keep track of your bounce rates to identify any sudden spikes that might indicate a problem with your email list or content.
Segment your list: Separate your hard bounces from soft bounces. Remove hard bounces from your list immediately and retry soft bounces after some time.
Use an email validation service: Validate email addresses before adding them to your list to minimize the chances of hard bounces.
