Great question. The accuracy definitely isn't 100%, but it's still pretty good. Gmail now loads images by default, as do most desktop (and mobile) email clients

Great question. The accuracy definitely isn't 100%, but it's still pretty good. Gmail now loads images by default, as do most desktop (and mobile) email clients. There are a few exceptions, but overall it's not as bad as it appears.
- rwantland 12y agoAgreed - Most mail clients do upload on auto.
- rbinv 12y agoIIRC, Gmail actually serves cached versions of embedded images using their own domains, which basically means that tracking pixels will get exactly one impression/hit (probably even regardless of the email actually having been opened or not).
