@sachin-maheshwari Can we support detailed form for from , ReplyTo and cc fields as suggested in https://github.com/sendgrid/sendgrid-nodejs/blob/master/packages/mail/USE_CASES.md#flexible-email-address-fields?

You mean following ?
//Email address with name
to: 'Some One someone@example.org'

That is default support as I tried...

{
"topic": "email.project.created",
"originator": "tc-notifications",
"timestamp": "2018-04-06T00:00:00",
"mime-type": "application/json",
"payload": {
"data": {
"subject": "3001032",
"name": "sachin m"
},
"recipients" : ["sachin <sachin@gmail.com>"],
"from" : "support <tc@topcoder.com>",
"cc" : ["cc@topcoder.com"]
}
}

No, I meant

//Object with name/email
  to: {
    name: 'Some One',
    email: 'someone@example.org',
  },

That is also supported you can try this.

Awesome. I would try. Would try the changes in dev.
