For that to work, the employee will need to have the "Modify All Data" as described [here](https://help.salesforce.com/apex/HTViewHelpDoc?id=email_logs.htm&language=en_US) | You can also add a Compliance BCC email address, which will be added to the BCC of every email that is sent out of your org. Of course, you'll get a lot more than just the emails generated by the apex script. I have a separate inbox for this purpose.

* if it opens a window (`window.open()`) it will get blocked by every popup blocker that is around
* if it uses `DIVs` to popup information (or any other `HTML markup`) it should work with standard popup blockers | @DhrubaJyoti Your answer is "Yes" your jquery popup will work even if the user has popup blockers enabled.
Popup blockers look for new "windows" (popups) to be created and then block them.
However, what jquery does is not create new windows but it just creates Modal Dialog's which as standard HTML elements on the webp... |
