Below Zero Chart

In previous versions, all email traffic—both passing and failing DMARC was stacked together in a single chart with a shared axis.

This created two key usability issues:

• Failing volumes were hard to see: Because the number of failed emails is often much smaller than the number of passing ones, the failure bars appeared tiny or almost invisible on the same scale.
• Grouping failures was unclear: Different failure types (e.g., accepted but unauthenticated, quarantined, rejected) were difficult to distinguish when compressed in a limited visual space.

In the new layout:

• Passing traffic is shown above the zero line, using one vertical scale.
• Failing traffic is shown below the zero line, using a separate, zoomed-in vertical scale optimized for low-volume data.

This approach brings several advantages:

• Improved visibility of failures: Even small volumes of rejected or quarantined emails now stand out clearly, making it easier for security teams to spot anomalies or patterns.
• Clearer group differentiation: Each failure type (Accepted, Quarantined, Rejected) is individually visible and colour-coded, making it easier to interpret the nature of delivery issues.
• Emphasises urgency: By visually separating and enlarging the failures, we highlight them more prominently—even if their volume is low—helping prioritise action where needed.
