It was getting frustrating that people were not responding to emails and that there was no way to know if the email was being ignored.
What it does
Tracks emails and notifies the sender when an email has been read by a return email.
How I built it
Challenges I ran into
Creating an image token that would not be seen by the recipient of the email. I ended up using a very small blank png image and used CSS to make the size of the image 1px by 1px so it is not seen.
What I learned
I learned more about email servers and email hacks especially email tracing.
What's next for Email Tracker
Public Extension Release for easier and seamless use(as in the pictures).
