# Domain Reputation with Google Postmaster
You can use Google Postmaster Tools to check the overall health of your domain. In addition, Google Postmaster Tools can be used to help monitor and debug all kinds of deliverability issues. One thing here to note is that the delivery reports are based on the emails sent to customers who Gmail use Gmail, for others, Google Postmaster does not show the reports.
## What is Google Postmaster?
Google Postmaster is a free tool that you can use to analyze your email performance and check your domain reputation. It provides all the details regarding the SPF/DKIM/DMARC failures, spam complaints, the reputation of your sending server's IP address, and more.
Google Postmaster is a really good tool and we recommend that everyone should set it up to check if there are any chances for improving the email delivery rates. With the kind of reports this tool gives, you can easily monitor and debug any issues related to email deliverability.
## How to set up Google Postmaster?
To setup Google Postmaster, you will need to signup on google postmaster and you will need to verify your sending domain with few DNS records. The authentication domain is the DKIM (d=) that is used to authenticate your email. Google Postmaster uses your DKIM to identify your email traffic and provide access to traffic analytics.
