Does my landing page seem too confusing?

Am not an expert on Email infrastructure, but I find it hard to understand the Use case, what problem is being solved.
Another challenge is, will this be a compliant solution, what about support? Perhaps those questions can be answered in FAQ.
Finally, a video to see it in action will help.

Yeep, you should do it more understandable. Don't forget that you have just a few seconds to grab someone's attention, if not, they will go. Try to explain your idea to 10y old and put some of the thoughts that you got on the web. But I like the design!
