Lead Capture Webform & Email

Increase sales by generating an Opt-in list. Visitors to website will fill in their contact info and be emailed specific reports. The trouble is that when I receive the email from my webform, their email address is buried in the text, and I want the system to automatically email back their chosen free report. I am open to various solutions including Outlook macros or VBA, or some other technology (javascript / php?). If we could automatically link Outlook to MS Access, this would be even better, but not a requirement at this stage. I have the "free reports", the website, and can create the webform. I receive the emails, but don't know how to automate the sending of the free report to the correct email address. Here is a sample of what the html side looks like: <FORM METHOD="POST" ACTION="http://www.x x x x x x [login to view URL]"> <p>First Name:<input type="text" name="firstname" class="textfield" size="20"> </p> <p>Last Name: <input name="lastname" type="text" id="lastname" class="textfield" size="20"></p> <p>Email: <input name="email" type="text" id="email" class="textfield" size="20"></p> <p>Choose your free report:</p> ****CHOICE OF SEVERAL; CHECKBOX FORM. This field will be used to email the specific report***** <INPUT TYPE="hidden" NAME="success" VALUE="http://www.x x x x x x x [login to view URL]"> <input type="submit" name="Submit" value="Submit"> </form> This will result in an email: New Lead: firstname lastname email: report chosen: I want outlook to automatically email the right report to the customer (and, if possible, add the name to a database). Thanks, I look forward to working with you
