I had 2 very specific needs that if this product did them both, it meant that I could reduce the number of plugins which also reduces my annual fees for those products. The first use case was simple, connect a Breakdance Form to MailPoet to store the info into a MailPoet list. Aside from a basic error I made, it was really easy. I got past my basic error with excellent support! They logged into my site, saw my simple mistake, fixed it and the integration works. My second scenario was a bit more complicated. I wanted to create a new record in a Custom Post Type (using Metabox) I have for the site. It took me less than 5 minutes to read their docs on how to do it, then set up the integration. It worked first time! I am now thinking of more use cases that I hadn't originally thought I would need this for, it is going to come in very handy!
