Just come across this. Haven’t dug too deep but sounds like an interesting opportunity. I think it can only succeed if it is fully compliant with current systems. Seems to only be mobile clients. No desktop? Are big tech going to permit this to grow? It would shut down a data mining opportunity …
Yeah, no. Email has always been an open standard. What is occurring is standard software allows filtering out spam (because people make money sending out spam) and then because centralized domain reputation inevitably occurs (because it is annoying hunting down bad actors and collectively it becomes easier) we end up with what we have today.
The solution is white list filtering in the hands of their users and people adding the senders that they want routed to their inbox but that is a user training problem that nobody wants to pay for.
