Automated Email Notifications using ASP.Net without Scheduler or Windows Service

Hi revathip,

As we know the WebServer IIS is continuously running, we can add a timer in the application and the timer can manage all these activities.

For this we have to make use of Global.asax file.

Global.asax

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup
    System.Timers.Timer timer = new System.Timers.Timer();
    // Set the Interval to 7 Days (604800000 milliseconds).
    timer.Interval = ((((7*24)*60)*60)*1000);
    timer.AutoReset = true;
    timer.Elapsed += new System.Timers.ElapsedEventHandler(TimerElapsed);
    timer.Enabled = true; 
}

public void TimerElapsed(object source, System.Timers.ElapsedEventArgs e)
{
    // Instanciate the Mail class.
    ScheduleMail scheduleMail = new ScheduleMail();
    // Call the send mail method.
    scheduleMail.SendScheduleMail();
}

ScheduleMail.cs

public class ScheduleMail
{
	public ScheduleMail()
	{
		//
		// TODO: Add constructor logic here
		//
	}

    public void SendScheduleMail()
    {
        // Send mail code goes here.
    } 
}

Hope this will help you to achieve your goal.
