I will continue being skeptical and hear me out.. (because your clients may also be skeptical).

Emails are by default not encrypted, so even if you claim (apologies - "trust no one") that you don't keep any data (well you MUST be at least keeping logs)(and how can we know that XYZ agency won't tap into your systems?) then the ISPs can sniff these stuff out.

I'm not trying to trash your product, it is a good thing to have if one needs it, but I am thinking of the risks (and so do all your potential clients).
