A/B testing allows you to experiment with multiple versions of your cadence emails to see which message resonates best with your prospects. Instead of guessing what will drive opens, clicks, and replies, you can run controlled tests and optimise based on real results.
With A/B testing, you can add up to five different email variants within a cadence step. Each variant can test subject lines, tone, structure, or calls-to-action — giving you insight into which approach performs best.
Why A/B Testing Matters
- Optimise engagement → Identify the subject lines and content that maximise opens and replies.
- Test messaging styles → Experiment with tone, structure, and CTAs to refine outreach.
- Data-driven insights → Replace guesswork with proven performance metrics.
How to Set Up A/B Testing
Step 1: Add Variants
- Go to your cadence and open the email step where you want to test.
- Click Add A/B Test to create new versions.
- You can add up to 5 email variants per step.
Step 2: Define Your Goals
- Decide what success looks like: higher open rates, more clicks, or increased replies.
- Tailor each variant to test one or more factors (e.g. subject line, message tone, or CTA).
Step 3: Launch the Test
- Start the cadence.
- Lead Onion will automatically distribute the variants across your audience.
Step 4: Analyse Results
- Review performance metrics for each variant.
- Compare open rates, click-throughs, and replies.
- Use winning approaches to guide future cadences.
Best Practices
- Test one main element at a time (subject line, content, or CTA) for clearer results.
- Run tests for long enough to gather meaningful data before deciding on a winner.
- Apply insights across future cadences for consistent improvement.
