Email templates with ASP.NET MVC 2, .NET 3.5 and Visual Studio 2008?

Question

I am trying to avoid using StringBuilder to generate e-mails and was hoping to find a solution to dynamically create e-mail templates using:

1. .NET 3.5
2. ASP.NET MVC 2
3. Visual Studio 2008

I have searched, but most seem to require .NET 4 or ASP.NET MVC 3+. Is there anything that would support my requirements?
