Message variants UI
Randomize message is Clapvo’s built-in A/B (or multi-variant) testing for broadcasts. Prepare multiple message variants for the same campaign and Clapvo distributes them randomly across recipients.

​
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.
