Why this matters
- Helps you discover which copy, offer, or call-to-action actually performs best.
- Avoids guessing wording - real audience response decides.
- Reduces the risk that one tired or low-performing message tanks an entire campaign.
- Protects sender reputation - repeating the exact same text to many recipients is a common spam signal, while randomized variants look more human.
Before you start
- Two or more message ideas you want to test
- Clear hypothesis: which element are you varying (headline, CTA, length, tone)?
Steps
1
Open the campaign builder
Create or edit a campaign.
2
Add message variants
Enter each variant of the message - same audience, different copy.
3
Enable randomize message
Turn on the variant rotation option.
4
Preview
Use the preview drawer to confirm each variant reads well.
5
Save and send
Clapvo distributes variants randomly across recipients.
Typical use cases
- Testing different headlines or opening lines on a promotional broadcast
- Comparing CTAs (for example, Reply YES vs Click here vs Book a slot)
- Comparing short vs long copy on the same audience
- Comparing message tone (formal vs casual) for the same offer
- Ongoing optimization of recurring templates used in sales follow-up or support nudges
Tips
- Vary one element at a time so you can attribute the difference to the change.
- Pair with Randomize sender for the strongest combination - multiple senders and multiple variants per campaign.
- Keep the winning variant; iterate on the rest next round.
