For starters, the development team is excellent; they accept and actually implement feedback. Originally, my review was a 3/5 tacos because there was no "webhooks" integration. They resolved this issue in less than a week. I've now fully integrated Active Pieces with Subpage, and I feel very satisfied. The JSON received is neat and intuitive.

The interface is beautiful because it is simple. It is very Notion-like. The ability to create an unlimited amount of lead magnets per organization makes this deal an UTTER steal.

However, there are a few minor drawbacks.
The following features are either not working or are glitchy (on Safari AND Chrome), below:

Video cannot be embedded, only YouTube, not manual upload.
Audio can only be embedded via URL and not via manual upload.
HTML block only partially works; I've tried using libraries like HowlerJS and VidStack.io to embed video players and audio players and this doesn't work (at all).

I feel a bit too lazy to add each of these issues to the company's "feedback" board, but are nonetheless worth mentioning to the AppSumo public.

Regardless, I've decided to give this deal a full 5 tacos despite those issues because:
1. They accepted AND implemented user feedback
2. They've given us the ability to create an UNLIMITED amount of lead magnets
3. The CENTRAL feature of this software product works VERY well, namely: the ability to CAPTURE emails...
4. WEBHOOKS is FINALLY here (as it should've been, to begin with)
