I bought this to sort my stuffed inbox, and despite searching high and low, I could not find any documentation on how to use the "new" feature to unsubscribe. Spoiler: it doesn't exist. Then, I realized there wasn't a scrap of contact info on the site or the account details. No social media contacts to reach out to. Brick wall. The user interface advertised is not what you get when you subscribe, and it doesn't collect all the mail from one sender. This is not faster. They've also redacted the contact info from WHO IS searches. 39 followers on LinkedIn and the unsubscribe feature advertised in their LI banner is not part of the UI. It all seems rather shady.
