# Case Study - AWeber

I wanted to share our latest case study with you, it's all about how our good friends at AWeber made the move from Momentum to KumoMTA. After watching engineering and support decline following the vendor being acquired, the AWeber team moved to KumoMTA for better architecture, greater transparency, and less risk.

> My personal favorite quote:
> 
> The most immediate benefit was unprecedented visibility into their email infrastructure. “Ultimately, it kind of boils down to transparency,” explained Roy. “MTAs like Momentum take a black-box approach. When a new version got released, we’d have little to no visibility into what changed. With KumoMTA’s open-source model, we could see the new elements as code that had been rolled into the release. As such, we could test it internally before we graduated it to production.”

Our users don't have to take our word for it, they can see for themselves what we're doing with every release.
