That's not cool at all. You can't tell your GMail to never block or mark as spam e-mails from the tormail.net or safe-mail.net domains?
Using gmail's "Not Spam" button you can retrieve a specific message from the Spam folder which will move it to the Inbox, but that is for "training gmail", and is an opaque process from there and is probably won't help much. Additionally, a filter can be set up so that specific email addresses (like a [email protected]) can be whitelisted (marked as "Never send to spam"), but there is not (to my limited knowledge of gmail) the ability to whitelist an entire domain. (it will let you add the filter *@tormail.net it just won't actually whitelist an [email protected] with that filter.)
e-mail sucks though and you are correct, that should not be the preferred method of contacting an organization.
Heh, ... competition is good! In fact, there have been many competitors (e.g., just for cash-in-mail in the U.S. we lost Bitcoin Morpheus and Bitcoin2Cash market for instance), ... and they're all gone now except for Get-Bitcoin. So while an exchange seems like it would be something profitable, smaller to mid-sized ones seem to exist more to help Bitcoin move forward than they appear to exist primarily for profit-seeking motives.
