Test your SMS and RCS content with A/B testing

February 2, 2026

NEW

You can now run A/B tests on your SMS and RCS One Shot campaigns to compare two variations and select a winner . The experience has been designed to remain consistent with Email A/B testing , while taking into account the specific characteristics of each channel.

Thanks to this new feature, you will now be able to:

Test 2 SMS variants and compare performance via clicks , if you have added tracked links.
Test 2 variants of RCS with a logic similar to Email A/B testing, testing open rates and clicks.
Iterate rapidly on your content to improve effectiveness, without changing your campaign strategy.

Where can I find this new product?

When creating a One Shot campaign, select SMS or RCS , then activate the A/B test option.

Important note: SMS messages don't have open rates ; the measurement is based solely on clickable links . If your message doesn't contain a link, a warning may appear (or the A/B test may be blocked). Use RCS to optimize your tests!
