You just need to define a system that sends mail upon an update in the news system. So if your site's news is updated by you typing something into a form and hitting update, the mails need to be sent after that form is processed.

thank you 'teknomage1 '
please explain me more about this subject.you have source program.
if you have ,send for me.thank you.

I don't have any source but I can explain a bit more.

Let's assume you have a traditional database backed web solution. Suppose you have a class that encapsulates your site's new functionality called 'clNews' . 'clNews' has some methods for displaying and updating the contents of the 'siteNews' database table.

So you have two ways of creating email alerts for news updates. The simplest solution to implement would be to keep a list of subscribers in another database table called 'newsSubscriber' . In the update method of the 'clNews' class the final line after the SQL query that updates the db would be to send an email to each subscriber from 'newsSubscriber' with the heading of the new article and a clickable link to the new article.

The alternative solution, especially if you have a large number of updates per day, would be to have a process that runs nightly, or weekly, that collects all of the headlines for that time period and sends a digest email.

I'd provide code, but I don't actually use or have the ability to use ASP or .NET
