Agree. A system with none of your friends or colleagues on is pointless because there is no one to talk to.

I'll try to be really clear about what Plum Mail is and is not! We haven't done a great job of communicating this thus far.

Plum Mail is NOT an email client.

Plum Mail IS a communication platform using a central server similar to how an instant chat platform works.

Where we differ is that Plum Mail isn't a 'walled garden' where you need to invite users in to use it.

Users are identified in the system by their email address. If you write to someone that is not a Plum Mail user, then we send that message out as an email to that user with an option to reply. That reply button gives the user immediate access to Plum Mail in order to write back to you. We're doing this passwordlessly. Right at the genesis of this idea we didn't want to build a system that required you to invite all your friends to it before it became useful.

Revenue wise, referencing the above point, Plum Mail has to be free. We will offer premium features for a modest fee.
