Example Output
Example 1: Deliverability Report
Deliverability Score: 7.2/10
Key Issues:
- Hard bounce rate (2.1%) is above industry avg (0.8%) — suggests list decay or stale contacts
- DKIM alignment: Missing (risk: Gmail may route to spam)
- Unsubscribe rate (0.3%) is healthy
Quick Wins:
1. Implement DKIM signing (2-3 min setup in Mailchimp)
2. Run re-engagement campaign on 45-day inactive segment (est. recover 12% of at-risk subscribers)
3. Enable double opt-in for all new signups
Example 2: Engagement Optimization Roadmap
Campaign: Q3 Product Updates
Current: 18% open rate, 2.1% CTR
Benchmark: 24% open (SaaS), 3.5% CTR
Week 1: A/B test subject lines (personalization + urgency)
- Test A: "[First Name], new features you requested"
- Test B: "48-hour early access — Q3 product launch"
Expected lift: +4-6% opens
Week 2: Segment by engagement tier; send mobile-optimized version to high-engagement segment
Expected lift: +1.2% CTR
Week 3: Analyze winning variant patterns; update template
Projected result: 22-24% opens, 3.2-3.5% CTR
