We offer a Free Plan that includes unlimited mobile push subscribers and up to 10,000 web push subscribers. Our aim is to provide a great free product, then offer more advanced features and higher volume usage on affordable, fair, value-rich plans. In contrast, many of VWO’s features can only be accessed in their more expensive products. VWO’s most basic offering, which includes web push and Facebook Messenger, begins at $99 per month for 10,000 subscribers. Optimizations like A/B testing are only available on VWO Engage’s Enterprise Plan.

Free Unlimited API Access

Whereas VWO restricts API access to its Enterprise Plan, we offer free unlimited API access because we believe that technical flexibility is a necessity in the messaging industry. We understand that every company, product, and use case is unique and we want you to have all the tools and resources you need to realize your vision. In addition to providing an open API, we pride ourselves on our detailed API resources and scrupulously maintained documentation library.
