How would that improve upon the existing MDN [1] system which relies on the client? [1]: https://en.m.wikipedia.org/wiki/Return_receipt https://en.m.wikipedia.

  Good question. I don't think they're mutually exclusive. It seems like existing client-side options don't cover these 3 uses that a third-party service might: 1. A recipient-specific "Do Not Track" option could apply to recipient-specific link/click tracking, not just open tracking. 2. Ideally, all email clients would have an option not to load images by default, but based on the comments in this thread, some don't. One popular example seems to be [Gmail for iOS](https://support.google.com/mail/answer/145919?co=GENIE.Platform%3DiOS&hl=en&oco=1 https://support.google.com/mail/answer/145919?co=GENIE.Platf...): "Images will always appear in the Gmail app on your iPhone or iPad." A third-party service could give some control to users of clients without this feature. (Whether the responsibility belongs on the sender, the recipient, or both is totally debatable and in practice, not very relevant. For all stakeholders, the goal is to communicate in a way that satisfies all parties well enough to keep communicating. Recipients have been at a disadvantage due to lack of information, and as their awareness increases, their expectations will rise.) 3. Right now, there's no way for companies which actually care about privacy and/or recipient preferences to stand out from those which don't, or which don't yet claim to. This would be one of few ways to discern white/light grey-hat senders and mail delivery services from dark grey/black-hat ones.
