SendGrid is a provider that allows SMTP
(Simple Mail Transfer Protocol) service. I
hope you’re aware of SMTP. It reduces your
time and efforts and provides flexibility
when sending large volumes of emails.

Why use
SendGrid in
NodeJS to
Send Emails?

Powerful email solution for sending
bulk emails with high deliverability
rates
Provides interactive and eye-catching
built-in email templates and freedom to
edit them as well
With the help of SendGrid, you can
track the real-time performance of
emails using various metrics like
bounce rates, unsubscribers, delivered
emails rate, unique reads/opens/clicks,
and many more.
Exceptional customer support
Sendgrid has been integrated with so
many tools that it lets you centralize the
marketing efforts. The API integration
with the various tools is very powerful.
Coming back to our next question, Why
SendGrid with NodeJS? No beating around
the bush, and here are the reasons why you
should use SendGrid for sending emails.

Create a NodeJs application using the below
command.

mkdir SendgridApp
cd SendgridApp
Initialize Project

npm init -y
It will create a package.json file.

We will install the required dependencies in
our project using the below command.

npm i express @sendgrid/mail dotenv

Open the root file of our project and name it
as your will.

// app.js

const express = require("express");
require("dotenv").config();
var app = express();
app.use(express.json())
const mailRoute =
require('./routes/sendMail')
app.use(mailRoute)
app.listen(process.env.PORT,
console.log('Server is up and running '+
process.env.PORT))

Visit SendGrid.com
Create an account
Choose a plan according to your
requirements
Generate API key
Let’s start with integrating Sendgrid.
For setting up the SendGrid account, follow
these instructions-

For sending emails from our NodeJS app, we
need to configure the SendGrid API key in
the application. The SendGrid gives you the
freedom to set up an email as per your
requirement. We can also add and modify
HTML, images, documents, etc.

// email/account.js

const sgMail = require('@sendgrid/mail')
require('dotenv').config()
sgMail.setApiKey(process.env.SENDGRID_
API_KEY) //your sendgrid api key
const sendMail = (email, name) => {
sgMail.send({
To: email, // receiver email address
from: 'fromemail@email.com',
subject: 'here comes subject line',
text: `here comes the body ${name}`
})
}
module.exports = {
sendMail
}

Send Mails
using
SendGrid in
NodeJs App

We can use the sendgrid function wherever
we want to use it, for example, when a user
is registering or leaving or for some other
notifications.

// sendMail.js

For this example, we are sending mail for a
specified route and call sendMail functions
as per our requirement.

const express = require('express')
const { append } =
require('express/lib/response')
const { sendMail } =
require('../emails/accounts')
const statusCode =
require('../constants/constants')
const router = new express.Router()

router.get('/sendmail', (req, res) => {
const user = req.body;
try {
sendMail(user.email,user.name)
res.status(statusCode.ok).send({message:
'Mail Sent'})
} catch (error) {
res.status(statusCode.internalServerError).
send({error})
}
})
module.exports = router
As for this example, we have manually set
the email or other required parameters that
we can send through postman.

Bingo, we sent mail successfully!
