First is Google, who we use for company email. This means any interaction with our customer support team has emails stored with Google.
If you self-host everything else, why don't you do the same thing for emails as well?
I can't speak for Foundation, but I do know that - especially with outgoing emails - self-hosting these days is a pretty big challenge.
Some providers will immediately flag your emails or delete them outright due to too strict firewall settings. Imagine a customer not receiving a response because their email provider didn't let Foundation team's reply through. That will probably be the main issue.
Maybe a support thread on Bitcointalk, together with support through DM (even if it may sound silly) could be a better way, avoiding email completely.
Do you have any official reseller stores in US and in other parts of the world that can sell Passport devices for cash or bitcoin in person?
I think this is a best way for reducing digital footprint and there is no risk of any leaks happening in future.
I agree that local and international brick-and-mortar resellers / distributors would be a great idea.
Though up until now everything was preorder - I don't believe that in-person preorders are very convenient; the customer would at least need to visit the store 2x. But on the other hand, they may actually be ready to do it.
Hopefully we'll see in-stock, in-person offerings around the world, after preorders are shipped!
Self hosting STMP servers is more trouble than its worth now days the one SaaS provider
pencil out spamscores being one of the hurdles for us , we've designed a system that provides anonymity via session hashstring.(the sting is essentially the receipt) you vault the strings when orders complete and purge libs, this system isn't retail investor friendly.
