CDO (Collaboration Data Objects) is an inbuilt ASP component used to send emails via ASP. It is widely used as a CDONTs replacement, because Microsoft discontinued the use of CDONTs on Windows 2000, Windows XP and Windows 2003 OS. CDO is the best choice to send emails from ASP based web applications, as it comes pre-installed with server OS like, Windows Server 2003, 2008 and 2012.
If you are still using CDONT component in your ASP application to send emails, you should update your code to use CDO. Below is a basic CDO script you can use to send emails. It's just a basic script, and you may have to customize it according to your requirements. You can find lots of web pages on the internet with more customizations and attributes with CDO.
