Marketing Metrics aggregates unique messages into delivery and engagement trends. Use it for overall health; use Marketing Logs when you need evidence for one message.

​
Open metrics

Go to Marketing → Metrics. The default view covers the last 30 days. Choose:
  • Last 24 hours
  • Last 7 days
  • Last 30 days
  • A custom range within the available 120-day window
The 24-hour range groups volume by hour. Longer ranges group it by day.

​
Filter by send type

Use Send type to compare: This is useful when a large broadcast would otherwise hide the behaviour of lower-volume automated email.

​
Metric definitions

Rates use these denominators:
  • Delivery, rejection, bounce, defer, and complaint rates: messages sent
  • Open and click rates: messages delivered
Delivery statuses can overlap. For example, a receiver can defer a message and later accept it, so Deferred and Delivered are not necessarily mutually exclusive.

​
Send volume

The volume chart groups messages by their send time. Hover a bar to see:
  • Sent
  • Delivered
  • Opened
  • Clicked
Look for sudden changes rather than treating one isolated hour or day as a conclusion. Compare the same send type and a similar audience when evaluating a campaign.

​
Delivery health

The delivery-health panel compares delivered, rejected, bounced, and deferred counts and rates. Investigate when:
  • Rejections rise after adding a domain or changing a sender
  • Bounces cluster after a new import
  • Deferrals rise at one recipient provider
  • Complaints increase after a content or frequency change
Open Marketing Logs with a matching date and status to see the receiver responses behind the aggregate.

​
Top recipient domains

This list shows the domains receiving the most messages during the selected range. It can reveal whether a delivery change is:
  • Account-wide
  • Concentrated at Gmail, Microsoft, Yahoo, or another provider
  • Driven by an unusual audience mix
Compare the provider distribution before and after a metric change. A campaign sent mostly to one provider is not directly comparable to one with a different domain mix.

​
Interpret opens carefully

Open tracking depends on a remote image loading. Results can be affected by:
  • Image blocking
  • Privacy proxies and prefetching
  • Security scanners
  • Cached images
  • Text-only reading
Treat opens as a trend signal. Clicks and product-side outcomes are usually stronger indicators of deliberate engagement.

​
From a metric to a diagnosis

1

Narrow the range and send type

Identify when the change began and whether it affects broadcasts or non-broadcast traffic.
2

Check recipient-domain concentration

Determine whether the issue is isolated to one receiving network.
3

Open Marketing Logs

Filter by date, status, sender, recipient, broadcast ID, or contact ID.
4

Inspect message timelines

Read the final receiver response, outbound IP, return path, and event sequence.
5

Correct the source

Fix DNS, list quality, content, frequency, or a broken destination based on the evidence.
