Mail encryption is vastly superior to HashCash, in my opinion, since
it protects the message content rather than merely wasting CPU effort.

Depends on context. One of the banks I use eschews all email contact
but has a contact form on their "secure" website. But generally
speaking, auto-replies of the type "you sent an email to
<user at example.com>, please click this link or reply to this
message..." result in my not bothering, and potentially doing business
with somebody who is easier to contact.

By the way, I tried to send a test message to myself from
<https://encrypt.to> but was thwarted by its assumption that the email
address for message delivery would be found in the recipient's key,
which mine is not. I then sent myself a test message encrypted to a
revoked key, so I guess either Encrypt.to or OpenPGP.js needs a bit
of tweaking.
