What is Google Postmaster Tools and why it matters to us

Updated on 2026-07-18

Google Postmaster Tools is a free tool from Google that we use at DISSAU to make sure the emails we send reach the inboxes of clients who use Gmail (addresses ending in @gmail.com).

Why we need it

Because no one likes important emails ending up in spam. With Postmaster Tools we can:

  • See whether Gmail trusts our emails.
  • Check if anyone marked them as spam.
  • Spot delivery errors.
  • Confirm we're following email best practices.

What it shows us

Once it's set up, we can see charts such as:

  • How many emails we send each day.
  • How many land in spam.
  • What reputation our domain has.
  • Whether there were email authentication issues.

What you need to do

Nothing technical. Just keep in mind:

  • Everything is already configured by our technical team.
  • If a client says "I didn't get the email" or "it went to spam," let the support team know so they can check it in Postmaster Tools.
  • If you notice several important emails going to spam, report that too.

What it needs to work

  • That we send enough volume to Gmail accounts.
  • That the DNS is correctly configured (our team already handled this).
  • A day or two after we start sending.
