title: How to Check Registration Expiration of User and send Notification by email in ASP.NET?
body: <p>I have a user registration form which has an expiration date. Within which the user needs to Activate his account within say within 30 Days of registration. Now i want to send him notification to such users who registered but not yet activated his account. I want to send him AUTOMATED EMAIL after each 10 Days. Say if user Registered at 1 Jan 2012 the notification email must be sent on 10 Jan 2012 that "Plz activate witin 20 Days" if current date is 20 JAN 2012 then " Plz Activate within 10 Days".(WITHOUT HUMAN INTERVENTION) i.e no need to click button to send mail. just must act as monitoring service.</p>

  <p>Plz Suggest me the right method!</p>
