You're spamming this post, that complains about spam from your product.

Makes me wonder if this "member of their project" is just some made up scapegoat.

> You are one of these 88 people

This thread is getting enough attention that I'm highly doubtful this message was only sent to 88 people. I saw the email, thought "I haven't subscribed to any HN digests lately", and deleted it.

So TL;DR: you produce a mailing list software, and someone used it to spam 88 HN users

Protip: it would probably be a good idea to spin off the spam-sending service (you call this “Creator”) into a new company, separate from the anti-spam service (you call this “Inbox”). I would guess the two userbases (spammers vs spammees) have a fairly small intersection.
