Email queue: Failed emails




The Email Queue enables Kentico Xperience to send emails without risking losing any of them to various errors. Emails that fail remain in the Email Queue with a status indicating their problem while successfully sent emails move to the Sent Emails tab.

Emails can fail to be sent for many reasons including server issues, smtp configuration problems, and connection issues. It is important to keep an eye on your Email Queue to monitor any problems that may occur in this system. Email lists and newsletters can often contain many thousands of recipients so failed emails can stack up quickly.

Check Logic

Constant Care for Kentico will ensure the number of failed emails in queue is no more than 0 (default)

You can manage your settings for this checkup in the Constant Care for Kentico admin settings.

Verifying The Check

In order to view your site's Email Queue you can navigate to the Email Queue application. The tab the application will default to is also labeled Email Queue.

From there you have the ability to filter the Email Queue as well as perform bulk operations.

It is often a good idea to keep your queue history for a short period of time (we recommend 7-14 days). You do not, however, want to keep these records for too long as it will hurt the performance of your site.


Changes to your site should only be made by an experienced Kentico Xperience developer. If you need assistance in making these changes please reach out to the Toolkit For Kentico team to be connected with a Kentico Xperience partner.
