I wish this help you I have setup and account on SendGrid. I have got the API key and Node.js methods. I am creating an web app with React js. I want to send emails through SendGrid. I am unable to find any solution. Please help me with my question with an example.
code :
class Form extends React.Component {
  constructor() {
    this.handleSubmit = this.handleSubmit.bind(this);

  handleSubmit(event) {
    const data = new FormData(event.target);

    fetch('/api/form-submit-url', {
      method: 'POST',
      body: data,

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label htmlFor="username">Enter username</label>
        <input id="username" name="username" type="text" />

        <label htmlFor="email">Enter your email</label>
        <input id="email" name="email" type="email" />

        <label htmlFor="birthdate">Enter your birth date</label>
        <input id="birthdate" name="birthdate" type="text" />

        <button>Send data!</button>

    const sgMail = require('@sendgrid/mail');
    const msg = {
      to: test@example.com',
      from: 'test@example.com',
      subject: 'Sending with SendGrid is Fun',
      text: 'and easy to do anywhere, even with Node.js',
      html: '<strong>and easy to do anywhere, even with Node.js</strong>',

NoMethodError: undefined method `email' for nil:NilClass : can't send email with devise/sendgrid(Rails 3.2)

it should still fix some issue That was a bit misleading, though a bit reckless on my end; the error was never from calling email on nil object (as the title stated), and I should've noticed that you're using Devise so all requests are handled by its RegistrationsController. That said, please change the title, and ignore or delete users_controller; it's not the one that's handling the registration requests.
Then add the following lines to your User model:
code :
after_create { Notifier.welcome_email(self).deliver }

Can't send email through SendGrid

it fixes the issue Does this happen to be a console application? I've been testing SendGrid and found that when I try to send an email from a Console application the emails are never sent. However, when I tried it from a web application (using the same exact sending code) the emails are sent. I have no explanation for why the console application does not work.

Using the sendgrid node-module, how do I send a SendGrid Template Engine email?

around this issue Yep, it's really easy, you just need to add it in as a filter. Here's how it should look:
code :
var cardEmail = new sendgrid.Email({
  to: "theuser@somedomain.com",
  from: "bignews@yourdomain.com",
  subject: process.env.SUBJECT,
  html: '<h2>Thanks for requesting a business card!</h2>', // This fills out the <%body%> tag inside your SendGrid template

// Tell SendGrid which template to use, and what to substitute. You can use as many substitutions as you want.
cardEmail.setFilters({"templates": {"settings": {"enabled": 1, "template_id": "325ae5e7-69dd-4b95-b003-b0109f750cfa"}}}); // Just replace this with the ID of the template you want to use
cardEmail.addSubstitution('-greeting-', "Happy Friday!"); // You don't need to have a substitution, but if you want it, here's how you do that :)

// Everything is set up, let's send the email!
sendgrid.send(cardEmail, function(err, json){
  if (err) {
  } else {
    console.log('Email sent!');

Can Azure Web App receive email SMTP, and send email (SendGrid)?

With these it helps Outgoing email using SendGrid will not be a problem at all. Using it on App Service is common and you probably don't need to change any code at all.
Inbound may require changes depending on what you're doing. Are you simply polling a mailbox somewhere else and then doing something with the messages? If so, you could convert that to a scheduled WebJob poll at a specific interval and act on incoming messages.

around this issue I am trying to send the emails via Sendgrid using v3 API doing so, I want to pass the json data similar to this , You need to add [] - brackets to your 'to' array. Please have a look.
code :
'to' => [
    [ // add this brackets
        'email' => 'ashuomble5@gmail.com',
        'name' => 'Ashutosh'
    ] // add this brackets
