As title state after my solution on aspx.cs I want to switch to another web page to remove cookies and avoid resending the same email.

Do the PRG pattern

After you done with your transaction, Redirect to another page (showing "It is done successfully" or some other message). Now Refresh can not beat you

To Redirect, You can use Response.Redirect method

 Response.Redirect("welcome.aspx")

You could add a Session which prevents the email being sent again (if this is a once per session email (ie. Newsletter sign up etc)).

Then check whether this Session exists before sending the email:

if (Session["emailsent"]==null){

  //Send email code here

  Session["emailsent"] = true;
}

you have to test in your page_load event

if(!IsPostBack)
{
//send mail...
}
else
{
//do nothing
}
