Step 2: Create an HTML Email Message

With the necessary modules imported, you can create your HTML email message. The EmailMessage class offers various methods to set the properties of your email, such as From, To, Subject, and Body. The From property specifies the sender, To for the recipient, Subject for the email subject, and Body for the message body.

The Body property can be a plain text string or an HTML file.

To create an HTML email message, follow the code below:

message = EmailMessage()
message['From'] = '[email protected]'
message['To'] = '[email protected]'
message['Subject'] = 'This is an HTML email'
with open('email.html', 'r') as f:
message.Body = f.read()

To Python send an HTML email, you need to construct the email’s HTML content. You can use basic HTML tags to structure your content and include styling to make it visually appealing.

For example, consider the following HTML email template:

<!DOCTYPE html>
<html>
<head>
<title>My HTML Email</title>
</head>
<body>
<h1>Hello,</h1>
<p>This is a sample HTML email sent using Python.</p>

<p>Best regards,</p>
<p>Your Name</p>
</body>
</html>

Step 3: Sending the Email Message

Now that we have our HTML email content, it’s time to compose and send HTML email Python.

We’ll use the smtplib library for the email-sending process. Here’s a step-by-step guide on how to do it:

  • Import the required modules.
  • Configure the email parameters.
  • Create the email message.
  • Send the email.

After crafting your HTML email message, you can use the smtplib module to send it.

The following code demonstrates how to send the email:

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login('[email protected]', 'password')
server.sendmail('[email protected]', '[email protected]', message.as_string())
server.quit()

Step 4: Adding Attachments to Your Email

In addition to sending HTML content, you should include attachments in your email. Python email HTML, email.mime library lets you easily attach files like images, PDFs, or documents to your emails.

Here’s how you can do it:

  • Import the necessary modules.
  • Create the email message.
  • Add the attachment.
  • Send the email.

You can enhance your HTML email messages by including attachments. To do this, use the attached method of the EmailMessage class. The technique requires a file object as an argument, which will be attached to the email message.

Step 5: Using a Template Engine

While manually constructing HTML content is a viable option, using a template engine like Jinja2 can significantly improve your email creation process.
