Which Email Tracker to use?

Email Marketing

Guys, please advise good email trackers for the following purposes:
1. Did the person open the letter?
2. How much time did he read it?
3. Did he follow the link in the email?
4. How long did he spend on the link?
5. The more information the service provides, the better :)
Thanks in advance
