I have recently been working on Mail4Net, a very interesting piece of software for .NET developers.
It includes software to create and manage email templates and a .NET class library for creating email messages from saved templates, populating data into the templates and then sending the populated email. You can also choose to save the email to a folder or to a database in SQL Server.
There is also a really good feature that allows you to add unit testing to your email code.
I will be blogging the articles on here and on the official Mail4Net blog: blog.mail4net.com
