Question

I am about to write a simple email manager for the site I’m working on (asp.net/c#); the site sends out various emails, like on account creation, news, some user actions, etc. So there will be some email templates with placeholders like [$FirstName] which will be replaced by actual values. Pretty standard stuff. I’m just wondering if someone can advise on existing code – again, i need something very simple, without many bells/whistles, and obviously with source code (and free)

Any ideas/comments will be highly appreciated!

Thanks,
Andrey

Answer 1

There are several threads on Stack Overflow about this already, but I ended up rolling my own solution from various suggestions there.

I used this FormatWith extension method to take care of simple templating, and then I made a basic Email base class to take care of common tasks, like pulling in an appropriate template and replacing all the requisite info, as well as providing a Send() method.

All the emails I need to send have their own subclass deriving from the base, and define things unique to them, such as TemplateText, BindingData, Recipients, and Subject. Having them each in their own class makes them very easy to unit test idependently of the rest of the app.

So that your app can work with these email classes without really caring which one it’s using, it’s also a good idea to implement an interface, with any shared methods (the only one I cared about was Send()), so then your app can instantiate whatever email class it wants and work with them in the same way. Maybe generics could be used, too, but this was what I came up with.

IEmail email = new MyEmailClass();
email.Send();

Edit: There are many more suggestions here: Can I set up HTML/Email Templates with ASP.NET?
