What is an A/B test in a WhatsApp broadcast?

An A/B test in a WhatsApp broadcast splits a sample of the audience randomly between two (or more) template variants, measures a chosen outcome (reads, replies, clicks, conversions) over a set period, and then sends the winning variant to the remaining audience. It is how teams learn which wording, header, offer or button works without guessing.

A/B test (broadcast)

An A/B test in a WhatsApp broadcast splits a sample of the audience randomly between two (or more) template variants, measures a chosen outcome (reads, replies, clicks, conversions) over a set period, and then sends the winning variant to the remaining audience. It is how teams learn which wording, header, offer or button works without guessing.

Why it matters

Small changes move WhatsApp results a lot: a button instead of a typed reply, a document header instead of text, a 10 am send instead of 6 pm. Testing on a sample first also limits damage: a variant that draws blocks is stopped before it reaches the whole list.

In VGraple CRM

The broadcast wizard offers an A/B mode with variant templates, sample size, metric and wait time; the winner is chosen automatically or by hand and sent to the remainder, and the report shows each variant's numbers. Both variants must be approved templates of the same category.

Frequently asked questions

How big should the sample be?
At least a few hundred per variant for a meaningful reply-rate difference.
Can I test send time instead of content?
Yes, with the same template on two schedules, or use send-time optimisation.
Does the test cost more?
No. Every recipient receives one message.
