Viewing Graphs

Every connection has a historical view of its metrics. From the Postmaster Tools list, click the Stats link on a connection.

The graphs page​

At the top you choose a domain and a date range (last 7, 30, or 90 days). Both selectors update all of the charts at once.

The page shows the data Google has published for that domain over the window:

  • Message Volume (inbound and outbound message counts, full width across the top)
  • Spam Rate
  • Delivery Error Rate
  • Authentication Rates (SPF, DKIM, DMARC on one chart)
  • TLS Encryption Rates (inbound and outbound on one chart)

The Message Volume chart sits on top because it is the context for everything below it: a rate only matters relative to how many messages it is based on, and the volume explains the gaps you see on the rate charts (those are the days, or directions, with no traffic).

Compliance status​

Above the charts is a Compliance Status card for the selected domain, showing Google's sender requirements as individual tiles: SPF and DKIM authentication, DMARC policy and alignment, DNS records, encryption, user-reported spam, and the two unsubscribe requirements.

Each tile is in one of three states:

  • Compliant (green): Google reports the requirement as passing.
  • Needs Work (red): Google reports it as failing.
  • No Data (grey): Google has not reported on that requirement. This is not a failure. Google only evaluates a requirement once it has enough mail from the domain to judge it, so a new or low-volume domain will show several of these.

The card always appears, even for a domain Google has published nothing for yet, so an unreported requirement reads as "No Data" instead of the section quietly disappearing. Last checked is when we last imported that domain.

Deliverability​

Underneath the tiles is Google's overall deliverability verdict for the domain:

  • Users signal that they want your email: a positive verdict.
  • Not enough outgoing email: Google does not have enough mail from this domain to form a verdict. This is not a reputation problem, and it is the same thing Google's own dashboard reports as "Not enough outgoing emails".
  • Users may not want your email: a negative verdict worth looking into.

When data is out of date​

If importing has stopped or is failing, a banner appears above the compliance card, so a flat or empty chart explains itself rather than looking like you have no mail:

  • This data may be out of date, when nothing has imported for more than two days. Google publishes with a 1 to 3 day lag, so this can resolve on its own.
  • We are having trouble importing this domain, when recent imports have failed. It includes the reason Google gave and the last time the import succeeded.

While imports are current, no banner is shown.

Reading the graphs​

  • Every domain in your connection appears in the selector, even ones with no data yet, so you can confirm a domain is connected before Google starts publishing.
  • Days where Google reported no data are left as gaps on the rate charts rather than dropping to zero, so a gap reads as "no data" instead of a failure. The Message Volume chart shows 0 on those days (zero messages is a real value).
  • The full date range is always shown, even if data only exists for part of it.

The history is back-filled (up to 90 days) the first time a connection imports, so the graphs are useful immediately.
