Most marketers track the wrong email metrics. They obsess over open rates while their revenue tanks.
I analyzed 200+ email programs to find the 7 metrics that actually predict success. Here's what matters.
Quick Answer: Email Marketing Metrics That Matter
The 7 KPIs that predict revenue:
- Open Rate - Are people seeing your emails? (Avg: 22%)
- Click-Through Rate - Are they engaging? (Avg: 2.5%)
- Conversion Rate - Are they buying? (Avg: 3%)
- List Growth Rate - Is your list growing? (Avg: 2.5%/month)
- Email Deliverability - Are emails reaching inboxes? (Avg: 95%)
- Revenue Per Email - How much money per send? (Avg: $0.10-0.50)
- Engagement Score - Overall list health (Avg: 70/100)
Track these weekly. Ignore everything else.

- Conversion rate: 3% (7.5 sales)
- Average order value: $75
- Total revenue: $562.50

How to Improve RPE
Quick wins (+$0.05-0.10 RPE):

Why it matters: Predicts future performance and deliverability

Weighted formula:

Example:
- Open rate: 24% → (24 ÷ 30) × 40 = 32 points
- Click rate: 3% → (3 ÷ 3) × 35 = 35 points
- Conversion rate: 3.5% → (3.5 ÷ 3) × 25 = 29 points
- Total Engagement Score: 96/100 (Excellent)
Engagement Score Benchmarks
| Score | Status | Action |
|---|---|---|
| 90-100 | Excellent | Maintain and scale |
| 75-89 | Good | Optimize weak areas |
| 60-74 | Average | Improve engagement tactics |

Average: 70/100
How to Improve Engagement Score
Focus on weakest metric:

- Low clicks? Improve content and CTAs
- Low conversions? Strengthen offers and landing pages
Overall tactics:
- Segment by engagement level
- Re-engage inactive subscribers

Metrics to IGNORE (Vanity Metrics)
These metrics don't predict revenue:
1. Total subscribers
- 10,000 engaged > 50,000 inactive
- Quality > quantity
2. Email sends
- Sending more ≠ more revenue
- Can hurt deliverability
3. Social shares
- Rarely correlates with revenue
- Nice to have, not critical
4. Time spent reading
- Interesting but not actionable
- Focus on clicks and conversions
5. Forwarding rate
- Low volume, hard to track
- Doesn't predict revenue
Focus on the 7 metrics that matter. Ignore everything else.
