Thanks for sharing that.
I would be very grateful if you could advocate for the email standards to be changed to include support for sealed (encrypted) senders.
Without this limitation, too much metadata is shared, and we should avoid referring to this service as a privacy-protecting messenger.
You omitted the timing of messages from your list of metadata: this can indicate the type of relationship, right?
