Use Cases and Deployment Scope
One of our clients (a restaurant that also ships some products nationwide) uses it for their email marketing. It was my first and only experience using the software, but I have used many other email marketing software over the years, and I just wasn't very impressed with the features that were provided, integrations, or email design/customization abilities.
