Hi Employer,
I have read your description and been interested in your project.
I have developed a web site that processes, analyse and extract the info from subject and body, that based on the content of the extracted info, sender email address, the system will do some actions as calculate the service cost (which set up by admin), subtract the credit, and have some strategies for the outgoing emails. The alert and notification system work good for invalid emails.
I'm ready to discuss and start to work on your project now.
