- Emails triggered by actions such as:
- Email opens and clicks
- Website visits or product page views
- Downloads of resources or event sign-ups
C. Lead Scoring and Automated Follow-Up
- Assign scores based on engagement
- High-score leads are automatically routed to sales teams
D. Re-engagement Campaigns
- Target inactive subscribers to reignite interest
- Example: Special offers or content reminders
E. Segmentation-Based Automation
- Dynamic campaigns based on demographics, firmographics, or engagement
- Ensures highly relevant content for each audience segment
