This program can be used for a variety of form needs including paid and non-paid events. I has greate branding flexibility and can be embedded or hosted by Cognito. I also like the eCommerce capabilities.
The interface was easy to nagivate. It includes drag and drop functionality which means the end-user doesn't need to know how to code.
In terms of the flow, each part of the process has a tab which includes building, creating the notification workflow, and including any eCommerce features.
You can also create templates which is handy.
You can also easily export the list from the system incase you don't have a workflow set up which makes it possible to create follow-up emails through your ESP or CRM. See below note on dislikes related to the follow-up email capabilities.
I like that I had several CRM integration options which included Microsoft Flow so I could tie it into the Dynamics CRM.
