How To Get Smtp Details From Sendgrid

When incorporating SendGrid, an online SMTP provider that facilitates email sending and receiving, it is essential to understand how to obtain your SMTP information from SendGrid. This is necessary for configuring your application’s SMTP settings. This guide will assist you in retrieving your SendGrid SMTP details.

Step 1: Create a SendGrid Account

If you haven’t already, the first step is to create a SendGrid account. You can do this by visiting the SendGrid website and clicking the Start for Free button. Follow the on-screen instructions to set up your account.

Step 2: Navigate to SMTP Relay

Once your account is set up, log in and navigate to Settings in the left-hand menu. Then click on SMTP Relay.

Step 3: Create a New API Key

Next, you’ll need to create a new API key. Click on the Create API Key button on the SMTP Relay page. You’ll be prompted to name your API key – choose something that will remind you what this key is used for.

Step 4: Retrieve Your SMTP Details

After you create your API key, SendGrid will provide your SMTP details. These will include your SMTP server (usually, your username (usually apikey), and your password (which will be the API key you just created).

Remember to store your API key in a secure location, as SendGrid will not show the key again for security reasons. If you lose your key, you’ll have to create a new one.

Step 5: Configure Your Application

Now you can configure your application with your SendGrid SMTP details. Here is an example of how you might do this using Node.js:

const nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
  host: '',
  port: 587,
  secure: false, // true for 465, false for other ports
  auth: {
    user: 'apikey', 

Remember to replace YOUR_SENDGRID_APIKEY with the actual API key you got from SendGrid.


Getting your SMTP details from SendGrid is a straightforward process that just involves creating an API key. Once you have these details, you can integrate SendGrid into your application to start sending and receiving emails!
