It can easily be argued that sending email notifications is a part of almost any Web application. Whether you’re developing small 2-tier apps to full n-tier enterprise apps you are more than likely going to wind up with the requirement to interact with customers/clients/users via email notifications.
There is literally and endless supply of email components available on the net today. Most of them are free to download and distribute, while other more advanced components can be purchased for a reasonable price. For me personally, I would rather implement my own functionality majority of the time rather than reading through support documentation and code samples trying to figure out how to make 3rd party components function with my existing application.
