How To Get Sendgrid Smtp

During the modern era of digital communication, the use of SMTP (Simple Mail Transfer Protocol) is crucial for sending emails. By using SendGrid, a cloud-based SMTP provider, you can effectively send emails over the internet. The setup process for their SMTP relay is straightforward and does not require any complex API integration. This blog post is intended to assist you in obtaining SendGrid’s SMTP service.

Getting Started

Before we dive in, you need to have a SendGrid account. If you don’t have one yet, you can sign up for free on their official website.

Step 1: Create SendGrid API Key

From your SendGrid dashboard, navigate to Settings > API Keys. Then, click on the Create API Key button. Provide a name for your key and select “Full Access” or “Restricted Access” as per your requirements. Finally, click on Create & View to generate the key.

Step 2: SMTP Relay Configuration

Next, you need to setup the SMTP Relay in the SendGrid dashboard. Navigate to Settings > SMTP Relay and click Create New SMTP Relay. Here, you will need to provide a name for the relay and the API Key you created earlier.

Step 3: SMTP Server Configuration

Now, it’s time to configure your SMTP server. The credentials and settings required are as follows:

SMTP Server:
Port: 587 (for unencrypted/TLS encryption) or 465 (for SSL encryption)
Username: apikey
Password: The API Key you created earlier

Step 4: Send a Test Email

Finally, it’s time to test your SMTP relay setup. You can send a test email from your application using your preferred programming language and the SMTP relay settings you configured.

For example, here is a Python snippet to send an email using the smtplib library:

    import smtplib
    from email.mime.multipart import MIMEMultipart
    from email.mime.text import MIMEText

    def send_email(subject, message, from_addr, to_addr):
        msg = MIMEMultipart()
        msg['From'] = from_addr
        msg['To'] = ', '.join(to_addr)
        msg['Subject'] = subject

        msg.attach(MIMEText(message, 'plain'))

        server = smtplib.SMTP('', 587)
        server.login('apikey', 'YOUR_API_KEY')
        text = msg.as_string()
        server.sendmail(from_addr, to_addr, text)

    send_email('Test Subject', 'Test Message', '[email protected]', ['[email protected]'])

Replace ‘YOUR_API_KEY’ with the actual API Key you created. If everything is set up correctly, your test email should be sent successfully.


With this, you should be able to successfully setup and use SendGrid’s SMTP relay for sending emails from your application. Happy Emailing!
