Last Channel Before Abandonment - Cosmise Attribution
See which marketing channel users last touched before dropping off to target smarter retargeting.
Abandoned Last Seen Channel Insights
Each client is tracked based on their last seen channel before abandoning or converting. Conversions are counted if the channel appeared at any point in the user’s journey.
High-effort abandoners are users who met default behavior thresholds.
This view helps highlight which channels drive intent but fail to convert — useful for retargeting.
What does this show?
Channels are listed with counts of people who converted or abandoned in the selected date range. Each card shows the channel name, total users, converted, abandoned, and high-effort abandoners when available.
What is on screen?
- One card per channel with its name in the header
- Metrics per channel: total users, Converted, Abandoned, high-effort abandoners (shown only when present)
- Conversion rate shown as a percentage next to Converted
- High-effort abandoner rate shown as a percentage next to high-effort abandoners
- Conversion rate formula: converted ÷ (converted + abandoned) × 100
How can I read this?
Compare cards by total users and the conversion percentage next to Converted. Look at Abandoned and high-effort abandoners to spot channels that drive activity without purchases in the same date window. Use the user totals to keep extreme percentages in context for small groups.
Examples
- If a channel shows 240 total users, 60 Converted (25.0%), and 180 Abandoned, the label next to Converted displays 25.0%.
- If a channel shows 90 Abandoned and 27 high-effort abandoners (30.0%), the line under Abandoned shows 30.0% for high-effort.
Interactions

Notes on the selected dates
All numbers reflect the currently chosen start and end dates. Changing the date range updates the channel list and every metric on these cards.
