Can someone help me with this automation script using QTP - To check links in the html emails.

We send thousands of email to our customers every day and with 15 different formats of template. Ofcourse, we can't go in each template and test each emails to make sure that the links works properly or not. I need someone to automate this as I have asked a lot many professional and they failed. The script should open outlook, find the emails with specific words in subject line, and from each emails, click on each links that are on the page, that includes the image links also (when a user clicks on image and a new window pops up). After the link is opened, verify that the page has not thrown any 404 error and verify some text from that page.

Can somone help me with this script. i would be very greatful
