How can I compare the performance of multiple push notification campaigns in a single dashboard?

Yes — you can compare several campaigns or individual push notifications on one dashboard, but the comparison is built with Filters, not with a breakdown. Dashboard breakdowns only support Platforms, Attribute values and Tag values; there is no "by campaign" breakdown.

How to set it up

1. Go to Analytics > Dashboards and create a new dashboard.
2. Add a widget and, in the Metrics section, pick the metric you want to analyze (for example message sends or opens).
3. In the Filters section, click the plus icon and choose the filter that matches what you are comparing:
   • Campaigns — filters by journey.
   • Push — filters by individual push message.
   • Aggregated Messages — filters by aggregated message.
4. Duplicate the widget once per campaign, each with its own filter value, and place the widgets side by side. That gives you a direct visual comparison of the same metric across campaigns.

Filter logic: several filters from the same group are combined with OR; filters from different groups are combined with AND.

Optional breakdown: inside any one widget you can still use the Breakdown field at the bottom of the chart to split that campaign by Platform (or by event attribute / tag values, where applicable). A maximum of five breakdown series are shown at once.

Repeat with additional widgets for other metrics such as open rate and CTR.
