# Messaging A/B Tester
Stop debating which message is better — test it. Generate messaging variants, deploy them through real channels, and measure which framing actually resonates with your ICP.
**Core principle:** At seed/Series A, you don't have enough traffic for website A/B tests. But you do have enough LinkedIn impressions and cold email sends to test messaging angles fast.
## When to Use
- "Which of these value props should we lead with?"
- "Test our messaging angles and tell me which works"
- "I can't decide between [message A] and [message B]"
- "What messaging resonates most with [ICP]?"
- "Run a messaging test for [product/feature]"
## Phase 0: Intake
### What to Test
1. **Core value prop** — The claim or positioning you want to test (e.g., "We help growth teams run outbound 10x faster")
2. **Test goal** — What are you deciding? (Headline for website, cold email angle, LinkedIn content strategy, ad copy direction)
3. **ICP** — Who should this resonate with? (Title, company type, stage)
4. **Current messaging** — What are you using today? (Baseline to beat)
### Test Channel
5. **Where to test:**
- **LinkedIn organic** — Post variants across consecutive days, compare engagement
- **Cold email** — A/B test subject lines or opening hooks via Smartlead
- **Both** — Run in parallel for fastest signal
6. **Sample size available:**
- LinkedIn: followers/typical impressions per post
- Email: list size available for testing
