Solution
If you want to know whether the user read your mail or not, then follow the below technique.
- Add one
image
with with dimension 0px*0px
inside the mail HTML
. - On
src
attribute of image
, provide one aspx
page link.
<img src="http://www.example.com/MyPage.aspx" height="0" width="0"></img>
- On
Page_Load
of that aspx
page, you can write any code to handle the request.
How it works?
So, when user opens the mail and reads it, the image points to the
aspx
page and the
Server Side Code
gets executed simultaneously.
When code gets executed, you can do anything like storing that in a
Database Table or logging to
Text Files. In that way, you would confirm that the user read your mail.
