Why does Postmaster show "No Data" for my domain?

GlockApps loads the domains and the respective data stored in your Google Postmaster account for the last 120 days and synchronizes its dashboard with the Google Postmaster data every 6 hours, ensuring you have up-to-date statistics on your domains’ performance. 

It is important to understand that you can add a domain for monitoring only in Google Postmaster. Then it will be loaded in the GlockApps Postmaster tool when your domain is verified.

In some scenarios, GlockApps Postmaster doesn’t show the domain’s metrics in its dashboard. The typical situation when you can see the “No Data” message for a domain is a low email volume. The data might be missing if the total number of messages for a given period is too low. In this scenario, the data is not available either in your Google Postmaster account or in GlockApps.
