# What Gmail Sees — Connect Postmaster Tools

> Link your domain to Google Postmaster Tools and see the spam rate Gmail's own users report — the one number no feedback loop can give you.

# What Gmail sees

Notifizz measures your deliverability from the signals it receives: bounces, spam reports forwarded by mailbox providers, blocklist checks. That covers most of the picture — with one structural hole.

**Gmail does not forward individual spam reports.** When a Gmail user hits "Report spam", Yahoo and Microsoft would tell us; Gmail does not. So for the mailbox provider that usually represents the largest share of a consumer list, our own complaint rate is blind.

Google Postmaster Tools closes that hole. Once your domain is linked, the **Reputation** page shows the spam rate Gmail actually measures, alongside what we measure ourselves.

## TL;DR

* Two clicks in your Google Postmaster Tools account: add our collector address as a user of your domain.
* You then see, per sending domain: the **user-reported spam rate**, the **SPF/DKIM/DMARC success rates on mail Gmail actually received**, and Gmail's **compliance status** with its bulk-sender rules.
* Gmail data lags 2 to 3 days, and Gmail publishes **nothing** below a minimum daily volume to its users — an empty panel is normal at low volume, not a failure.
* A spam rate above the threshold raises your reputation level in Notifizz automatically, and can pause marketing sends.

## Link your domain

<Steps>
  <Step title="Copy the collector address">
    It is shown on the **Reputation** page in Notifizz, under *What Gmail sees*, with a copy button.
  </Step>

  <Step title="Open the user management screen for your domain">
    The same page gives you a direct link per domain. It points at
    `https://postmaster.google.com/v2/manage_users?domain=YOUR-DOMAIN`.

    <Note>
      That screen is not reachable from any menu in the current Postmaster interface — the direct link is the shortest way in. If your domain is not registered with Google yet, add it there first; Google will ask you to confirm ownership with a DNS record.
    </Note>
  </Step>

  <Step title="Add the address as a user">
    Paste the collector address and confirm. That is the whole gesture: we read your statistics, we never send on your behalf from that account.
  </Step>

  <Step title="Wait for the first sync">
    Notifizz reads Postmaster once a day. The domain moves from "not linked" to showing data on the next sync — sooner if you already have Gmail volume.
  </Step>
</Steps>

## Reading the numbers

**User-reported spam rate.** The share of your delivered Gmail mail that recipients marked as spam. Google's published bulk-sender rules put the line at **0.10 %** as a target to stay under, and **0.30 %** as a level to never reach. Those are the same thresholds Notifizz uses everywhere else, so the two views line up.

**Authentication rates.** The share of mail Gmail received that passed SPF, DKIM and DMARC. This is different from the DNS check in **Domains & DNS**: that one verifies your records are published correctly, this one reports what actually happened to real mail. A gap between the two is worth investigating — a forwarding path that breaks signatures, or a third party sending under your domain without you knowing.

**Compliance status.** Gmail's own verdict on whether you meet its bulk-sender requirements, with a recommended action when you do not. We display it exactly as Google words it.

<Note>
  Postmaster Tools does **not** report inbox versus spam placement — no tool from a mailbox provider does. It reports how your mail behaves and how recipients react to it.

## FAQ

<AccordionGroup>
  <Accordion title="Why is my panel empty?">
    Two different reasons, and Notifizz tells you which one. **Not linked**: our collector has not been added as a user of your domain yet. **Not enough volume**: the link works, but Gmail does not publish statistics below a minimum daily volume to its users — you will see data once you send enough Gmail-bound mail regularly.
  </Accordion>

  <Accordion title="Do you get access to my whole Google account?">
    No. Adding a user to a domain in Postmaster Tools grants read access to that domain's delivery statistics, nothing else. No mailbox, no sending rights, no other domain.
  </Accordion>

  <Accordion title="Where did domain and IP reputation go?">
    Google retired both in September 2025, judging them hard to act on and often misleading. They were replaced by the compliance status, which states a verdict and a recommended action instead of a score.
  </Accordion>

  <Accordion title="Why is the spam rate different from the one Notifizz shows elsewhere?">
    Because they measure different things. Ours counts the reports mailbox providers forward to us — and Gmail forwards none. Gmail's number is the only accurate one for Gmail recipients; ours covers the providers that do send feedback. Both are useful, which is why both are shown.
  </Accordion>

  <Accordion title="What happens if the Gmail spam rate goes above the threshold?">
    Your reputation level in Notifizz is raised accordingly, and at the critical level marketing broadcasts are paused automatically while things recover. Transactional emails are never affected.
