The biggest missing feature on Masked Email by Fastmail is they don't remove trackers, as far as I know.

Masked Email gives you more privacy (the identity behind the receiver is unknown) and with data breaches, there's is no login data leaked.

Duck's Email Protection does also remove trackers from the forwarded mails. So senders can't trace back whether you have opened the mail. I hope they also remove click trackers, but I am unsure how they would implement that technology with the referral codes in the URL.

Fastmail proxies all images (when using their webmail interface), and AFAIK remove tracking images. https://fastmail.blog/privacy-security/fastmail-keeps-you-sa...

Reads are still tracked by virtue of the fact that the image was requested. Proxies do obscure the requester's IP address, but not much else.
