Tips for Best Results
- 1.Provide actual subscriber counts and recent engagement data for more accurate segment size estimates. Generic responses improve significantly with real numbers.
- 2.Include your email platform name (HubSpot, Klaviyo, Mailchimp, etc.) so the AI can suggest platform-specific implementation steps and available data fields.
- 3.Ask the AI to create a 'segment decision tree' as a follow-up—this helps your team quickly identify which segment each new subscriber belongs to.
- 4.Request a 'quick wins' version focusing on 2-3 high-impact segments you can launch in 2 weeks, then expand to the full strategy later.
