Would creating different themes for your forms be an option? An example theme can be found here, its just html so you can do whatever you want really: Views/Partials/Forms/Emails/Example-Template.cshtml

Hi Amir.

I do not se how i can set headers in the .cshtml. Am i missing something?

I was thinking that there might be a way to hook into the mailmessage, like there is in NewsletterStudio. But i can't find any documentation on it at https://our.umbraco.com/documentation/Add-ons/UmbracoForms/Developer/

Like?

public class AddCustomMailHeaders : UmbracoFormsHook
{
    public override void ProcessSomething(MailMessage mailMessage)
    {
       mailMessage.Headers.Add("Custom", "Header");
    }
}

I was told by Umbraco Support, that this is not something that comes out of the box with Umbraco Forms.

So for you to achieve this what you need to do is to create a custom workflow type. You can follow the following documentation on how to create a custom workflow in Umbraco. https://our.umbraco.com/documentation/Add-ons/umbracoforms/developer/extending/adding-a-workflowtype

I made a request for it here https://github.com/umbraco/Umbraco.Forms.Issues/issues/151

is working on a reply...
