Quick Answer
What does Google Postmaster Tools help you monitor?
Google Postmaster Tools gives you visibility into how Gmail views your sending domain, including domain reputation, IP reputation, spam rate, authentication, and delivery errors. After adding and verifying your sending domain, use those signals to identify deliverability problems and improve your sending practices.
Seeing How Gmail Actually Treats Your Emails
You may be sending emails consistently, but it is not always clear how Gmail views your domain or sending behavior.
Google Postmaster Tools provides visibility into reputation, spam rates, authentication signals, and delivery errors that can affect inbox placement.
This information can help you identify deliverability problems before they become more serious and give you clearer direction when your Gmail performance starts to decline.
Consistent sending makes the data more useful
Avoid large sending bursts when possible and aim for steadier sending volume. Consistent behavior makes reputation trends easier to evaluate over time.
Google Postmaster Tools at a Glance
Before You Begin
Make sure you can verify ownership of the sending domain you want to monitor.
- Have access to the Google account you will use with Postmaster Tools.
- Know which sending domain you want to monitor.
- Have access to the DNS settings for that domain.
- Be prepared to add the TXT verification record Google provides.
- Allow time for DNS changes to propagate if verification does not work immediately.
What You Can Monitor
Spam Rate
See how often Gmail users mark your email as spam.
Domain Reputation
Review Gmail's trust rating for your sending domain.
IP Reputation
Review Gmail's trust rating for the IP addresses sending email on your behalf.
Authentication
Monitor SPF, DKIM, and DMARC authentication signals.
Delivery Errors
Look for signals showing that mail is being rejected or throttled.
Step 1: Set Up Google Postmaster Tools
Verify ownership of your sending domain by adding the DNS TXT record supplied by Google.
Step 1: Sign In to Google Postmaster Tools
Sign in to Google Postmaster Tools using your Google account.
Step 2: Add Your Sending Domain
Select the option to Add Domain and enter the sending domain you want to monitor.
Step 3: Copy the TXT Record

Step 4: Add the TXT Record to DNS
Open the DNS settings where your domain is managed and add the TXT record exactly as provided.
Step 5: Verify the Domain
Return to Google Postmaster Tools and select Verify.
If verification fails
DNS changes can take time to propagate. Wait and try again, and double-check the TXT record for typing or formatting errors.
Step 2: Connect Postmaster Tools in BizStackPro
After the sending domain is verified in Google Postmaster Tools, connect the service inside BizStackPro so you can review the available deliverability information more conveniently.

Go to Email Services.
Step 3: Find Postmaster Tools
Locate the Postmaster Tools section or the related deliverability area.
Step 4: Connect the Account
