SendGrid email read confirmation

Question

I want to collect information about how many emails that I have sent, has been read. I want to use method where I will put image in email and once the image gets rendered I can catch that event. I know this is not hundred percent reliable.

I am using a SendGrid for sending my emails. I was wondering does SendGrid provides service like this?

I was looking through SendGrid documentation but was not able to find what I need.

You want to use the Open Tracking app. You can also enable, disable, and configure this app via the web API or SMTP API headers.
