I'd gladly pay $2 to retire my army of throwaway emails, assuming the service remains as currently advertised. How many email domains do you have available to choose from, and how do you plan to deal with vendors potentially banning your domains?
This is more of a general thought, but privacy is another concern. There are plenty of companies who took customers' money and then sold their private data anyways. I'm more inclined to trust a startup like yours, but somewhere down the line I see this as a possibility. Is there ever a way for a customer to be sure a company isn't misusing their data? Are there any 3rd parties who can confirm/audit their practices?

I'm still new here, but from what I've seen it's probably okay as long as the context is relevant. I see people pushing startup solutions on a daily basis and it's usually cool stuff.
