> FlashDrive’s containers can be used to send emails but the architecture of FlashDrive uses a single IP address by datacenter to provide ultra high redundancy. Since this IP is advertised by any container using FlashDrive inside the same datacenter it’s highly possible that this IP will be blacklisted pretty quickly by any major email provider. For that reason we don’t recommend the use of FlashDrive’s architecture to send emails.

> We are working on a solution to associate a dedicated static IP to an app for a little additional monthly fee and we will release this solution shortly.

Are there other aspects of the architecture where tenants are not isolated from each other?
