I am following the guidelines as described here
https://developers.google.com/gmail/schemas/reference/one-click-action
But It's just wont appear for me. As described here
Self testing
You can easily test if your markup is working correctly end-to-end by sending emails with schemas to your Gmail account. All emails where the sender and the recipient are the same account ignore the registration requirements and can be used for self-testing.
I am using my same gmail address in both to and from address like below
GradeCard gc = new GradeCard("105106265", "BTS");
var m = new UserMailer().ConfirmSubscription("Shashwat", "user@email.com", new WatchListEmail() { fullName = "from Model", gc = gc });
Response.Write(m.Body);
var client = new SmtpClient("smtp.gmail.com", 587)
{
Credentials = new NetworkCredential("user@email.com", "xxxxx"),
EnableSsl = true
};
client.Send(m);
HTML of generated mail is like this
<!DOCTYPE html>
<html>
<body>
<div style="width: 600px; margin: auto; font-family: 'Segoe UI';">
<h1 style="font-weight:lighter; border-bottom:1px solid #808080; padding:5px 0;">example.com</h1>

If you check the email headers, I'd expect that no DKIM/SPF signature can be found, and that is required even for self-testing. Without the signature, anyone can spoof your email address and send you unwanted email with actions.
You have to be approved by Google first, in order for it to work.
To do this:
Send your validated schema-containing email to a special google email address (use this tool: https://www.google.com/webmasters/markup-tester/u/0/) ... then:
Fill out the "Gmail Schema Whitelist Request" form that describes your website and what you intend to do with the one-click action. Here's the form: https://docs.google.com/forms/d/1PA-vjjk3yJF7MLPOVKbIz3MBfhyma2obS8NIZ0JYx8I/viewform?pli=1&fbzx=-1177483801701354615
