Developing email tracking app
The organization where I work have asked me to look into the possibility of sending email to our customers which we can track i.e. when customer opened email etc.
I know such services are available but we want to develop in house due to some policy regulation.
I know that we can include a pixel in email through which we can track BUT aren't email clients by default block loading images so this approach will fail? But then how other service providers track email? Or is it expected that customer must allow loading images and this is also how other service providers also work?
What I have researched so far, it is impossible to track 100% using in house tools as there are specialized service providers for exactly this kind of work. But just want to have some brain storming/ideas sharing to make it work in house (whatever is possible)

Comments
Do they realize that email tracking is something most people using email actually detest? Consequently, many webmail apps and other clients already have built-in mechanisms to prevent tracking.
