Step 5: Continuous optimization

Improvement based on data:

MONTHLY ANALYSIS:

A/B TESTS (on part of list):
Test email subject:

- Version B: "[First name], your safety checklist of the month"
→ Keep version with better open rate

Test CTA:

- Version B: "Book my free audit"
→ Keep version with more clicks

Test length:
- Version A: Short newsletter (300 words)
- Version B: Long newsletter (600 words)
→ Analyze engagement

EVOLUTIONS:
- If open rate ↘: Vary subjects, send times
- If CTR ↘: Improve CTA, more engaging images
- If unsubs ↑: Reduce frequency or review content relevance

COLLECT FEEDBACK:
