Sending a reply with original email content quoted below

[SKempin]

Issue Summary

I'm trying to send a reply as a thread, where the original email content is quoted below the reply content (as a standard email reply has).

Following https://github.com/sendgrid/sendgrid-nodejs/issues/482#issuecomment-641747083 and https://github.com/sendgrid/sendgrid-nodejs/issues/690#issuecomment-393336215 I have been able to create reply (which is successfully grouped as a thread) but the reply email itself doesn't include the previous email content as quoted content.

As there is a lack of documentation for replying in general I am unsure how to achieve this?

Steps to Reproduce

1. Use Inbound Parse to post RAW message content to API endpoint
2. Use simpleParser to parse email content
3. Send reply as snippet below
4. Reply is received but doesn't include the original email content as quoted content.

Code Snippet

  const parsedEmail = await simpleParser(req.body.email);
  const msg = {
    to: parsedEmail.from?.text,
    headers: {
      References: `${parsedEmail.references} ${parsedEmail.messageId}`,
      'In-Reply-To': parsedEmail.messageId,
    },
    from: 'myemail@mydomain.co.uk', // actual email removed for the purposes of this snippet
    subject: `Re: ${parsedEmail.subject}`, // where subject is the sender's subject.
    text: 'This is the reply from SendGrid',
  };

Technical details:

• sendgrid-nodejs version: 7.4.2
• node version: 14.16.0

@thinkingserious I submitted this as an issue but the team was unable to support. Is this not possible to achieve?

For anyone looking for this behaviour I was able to emulate the formatting by wrapping the content in block quotes:

<blockquote type="cite">
    On ${datestamp}, at ${timestamp}, ${from} wrote:
    <br /><br />
    <div>${originalEmailContent}</div>
  </blockquote>
