Question

Answer 1

If you really have no control over the server (meaning, you cannot use an sql job, a scheduled task, or install a windows server) then you could use a System.Threading.Timer that you initialize in your Global.asax (e.g, on application startup) that invokes a certain method in your application every x minutes. This method would then query your database and see what notifications need to be send.

This is really not a desirable approach though, as the timer is not guaranteed to always invoke as far as I know, since, like Peter says, your web application is not guaranteed to be alive at all times.

However, depending on your requirements, it can still be a 'good enough' approach if you have no other options.
