Done sending emails to all the users in our mailing list. Lets now create a 'del.asp' page whose link we have already added in our messages. Users will be able to delete their emails from out database if they want it by clicking the link we provided to them in their emails.

Note if you are getting errors when testing this script on your own computer, then search in the 'windows/sytem/' diretory ( win95/98 users ) or 'winnt/system32' directory ( winnt/2000 users ) if 'cdonts.dll' is present there or not. If it's not then get it from the Windows CD or search it on www.microsoft.com. You should change the URL provided in above code for the email deletion page to the URL where that 'del.asp' page will actually reside.

ASP Email Deletion Page
Create a new page and add the following lines of code into and then save it as 'del.asp' in the same folder where you have kept other pages :

	<%
' Declaring variables
Dim email, con, data_source, sql_delete
email = Request.QueryString("email")
sql_delete = "delete email from users where email = '" & email & "'"
data_source = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _ 
	
	Server.MapPath("mail.mdb")
Set con = Server.CreateObject("ADODB.Connection")
con.Open data_source
con.Execute sql_delete
con.Close
Set con = Nothing
Response.Write "Your email address " & email & _ 
	" was successfully deleted from our database."
	%>

We are now done with creating our ASP based news letter for our site. I have delibrately kept things simple so that beginners can also understand whats going on. You can add your own features to it as you want.
