Using a render task an developer can hook into the rendering process of the email and make changes to the message body/subject. This can be done both on an overall level and on each individual email (ie. personalization). This feature could for example be used to replace [sometext] inside the message with a value from some other source. All rendering that happens inside Newsletter Studio is built with render tasks and they are all configured inside the newsletterStudio.config.

Create a custom render task

Creating a custom render task is very straight forward. Just inherit the base class " NewsletterStudio.RenderTasks.RenderTask" and override these three methods:


When you have your class ready, just put the DLL inside the bin-folder and add you render task to the list in /config/newsletterStudio.config.

Parameters to render tasks

The render tasks are passed parameters for you to use in the creation of your task. You can use them in different ways, one way could be to add extra headers to the message that are sent, this is done in the "ProcessUniqItem"-method.
 

public class AddCustomMailHeaders : RenderTask
{
    .....
    public override void ProcessUniqItem(RenderResult renderResult, RenderTaskUniqItemParameters parameters)
    {
       parameters.MailMessage.Headers.Add("Custom", "Header");
    }
}
