Consistent testing compounds into competitive advantage.

Testing roadmap:

• Month 1: Test length (short vs long)
• Month 2: Test personalization (name vs no name)
• Month 3: Test emojis (with vs without)
• Month 4: Test triggers (curiosity vs benefit)
• Month 5: Test specificity (numbers vs vague)
• Month 6: Combine winners and optimize

After 6 months of systematic testing, you will know your audience better than anyone.
