I agree that your pricing model is more user-friendly and it's more inline with your cost model (mailboxes are free to provide). It's why I clicked on it. I spent about 3 minutes given my browser history, looking at your homepage and pricing page. What I absorbed, after seeing your HN "email from $4/mo" and then your homepage, was that this was primarily about being cheap. Maybe I'm an outlier, but that seemed to be the message you were sending me.

And I totally understand you're not trying to "Tech Crunch", I think a SaaS is a great side business -- i've done this myself -- but also the only way to ensure stability of a project over long term is for it to provide financial rewards inline with effort.

Also, I definitely should've added: Congrats on shipping.
