What are Server Logs?
Server logs are files that record activities and transactions on a server. In the context of
email marketing, server logs provide a detailed record of how emails are processed, delivered, and interacted with. These logs are essential for troubleshooting issues, optimizing campaigns, and ensuring compliance with regulations.
Timestamp of the transaction
Sender and recipient email addresses
Delivery status (delivered, bounced, deferred)
Error messages and codes
IP addresses of sender and recipient servers
Spam filter interactions
How to Access Server Logs?
Accessing server logs depends on the
email service provider (ESP) or the server configuration. Most ESPs provide access to server logs through their dashboards. For self-hosted servers, logs can typically be found in the server’s file system under directories like /var/log/ for Linux servers or \Windows\System32\LogFiles\ for Windows servers.
2xx codes indicate successful delivery.
4xx codes represent temporary issues, often related to recipient server problems.
5xx codes denote permanent errors, such as invalid recipient addresses or blocked emails.
SMTP error codes provide specific reasons for delivery failures, such as “550 Requested action not taken: mailbox unavailable.”
Identifying high bounce rates can indicate issues with the email list quality.
Frequent delays may suggest problems with the sending server or network.
Tracking spam filter interactions helps in fine-tuning content to avoid spam triggers.
Regularly reviewing server logs allows for proactive measures to enhance
campaign success.
