Ello.co protects your privacy! - not

So I've read more about ello.co. They protect privacy (so they say), don't sell user data and allow fakes. My call.

However, there's a pitfall:

Received: from o167893375.outbound-mail.sendgrid.net (o167893375.outbound-mail.sendgrid.net [167.89.33.75])

As you can see, the registration email came from sendgrid.me. Not from Ello. Now sendgrid.me knows the email address I've solely dedicated for my Ello account.

And the email contains a couple of links which look like this:

So much about privacy.
