Greetings Iterable Community,

Measuring the effectiveness and high-level impact of your marketing campaigns just got a whole lot easier!

I’m happy to share with you the release of Holdout Groups, a new feature that allows you to measure the effectiveness and impact of your marketing campaigns against a custom conversion event within an experiment.

Easily define and exclude a subset of your audience from receiving an email, SMS, mobile in-app, push campaign, or web push message and analyze the uplift in purchases or a select custom conversion event from those who have received the campaign against those that have not.

Holdout Groups is now available to all customers and located within the “Experiments” page for email, mobile push, and web push blast campaigns. To learn more about this new feature, visit our release notes and please share your questions or feedback about this feature below. Thanks!
