Postal add custom header

Question

I am using Postal.NET for email in my C# MVC application:

I am using SendGrid for sending out emails. Sendgrid requires custom header arguments to be sent using the "X-SMTPAPI" header attribute.

How can I add custom header values in Postal.NET? (e.g. myMessage.Headers.Add("X-SMTPAPI", jsonString);

Not sure why someone has to down vote the question when they really don't know how to answer. Can I know the reason for down voting this? — Abhi, Dec 11 '16 at 08:18
Just out of curiosity, do you even understand my question? I very well know what SO is for. Thanks — Abhi, Dec 11 '16 at 09:06

I haven't used this library, but it looks to me like you can just add headers in the view above the email. That is the view you create contains the entire email--including headers. In the documentation you can see that To: and From: are included in the view. This is from the documentation:

To: @ViewBag.To
From: lolcats@website.com
Subject: Important Message

Hello,
You wanted important web links right?
Check out this: @ViewBag.FunnyLink

So I think you could likely do something like:

X-SMTPAPI: @ViewBag.jsonAPIString
To: @ViewBag.To
From: lolcats@website.com
Subject: Important Message

Hello,
You wanted important web links right?
Check out this: @ViewBag.FunnyLink

<3

This worked for me using the Reply-To header. Thanks. – Meryovi Oct 14 '17 at 17:07 — Meryovi, Oct 14 '17 at 17:07
