From understanding campaigns to working with subscribers, a broader role for the email expertise you already rely on.
Understand performance
Investigate changes, compare campaign results, and identify where to focus using connected ESP reporting and sending signals.
“Compare last week’s campaign performance.”
Work with your audience
Bring connected subscriber segments together with verification, 0–10 engagement scores, and enrichment to inform audience analysis and targeting.
“Help me identify the right audience for my next campaign.”
Move work forward
ESP tools expand the agent’s role beyond reporting into email operations. Campaign and audience tools provide the building blocks; supported actions depend on the connection.
