Common metric combinations

• Open rate analysis — combine Unique opened ÷ Total recipients from Sent campaigns, broken down by Sent date or subject line

• List growth over time — use Subscriber lists + People with a date filter to track subscriber additions

• Suppression vs. active — join Suppression lists with People to calculate deliverable audience size

• Campaign volume by client — join Clients with Sent campaigns to report on activity per client (agency accounts)

Use cases by role

Marketers

• Track open rates, click rates, and unsubscribes across all sent campaigns in a single Google Sheets dashboard

• Use the Aggregate transformation to roll up campaign metrics by month or quarter

• Export Segments and Tags data to understand how your audience is categorized and whether segments are being used effectively

• Send campaign performance data to ChatGPT or Claude to generate written summaries or identify underperforming campaigns

Agency teams

Ops & compliance

Platform-specific notes

• The start date parameter applies to time-based entities like Sent campaigns — use the date picker to limit how far back the sync reaches

• Agency-level API keys return data across all clients; client-level API keys are scoped to a single client

• Draft campaigns and Scheduled campaigns do not include performance metrics — those only appear after a campaign is sent

• Custom fields on subscriber records vary per account — they'll appear as additional columns in People exports

• Suppression lists are account-wide and not tied to individual subscriber lists
