How to add the images in smtp mail body
To add images to the body of an SMTP email, you'll need to use a combination of HTML and base64 encoding. Here's a step-by-step guide:
Step 1: Convert the image to base64
Use a tool like base64
command-line utility or an online converter to encode the image file into a base64 string. For example:
base64 -i image.jpg
This will output a long string of characters that represents the image data.
Step 2: Create the HTML email body
Create an HTML file that contains the email body and the image. For example:
<html>
<body>
<img src="data:image/jpeg;base64,[base64_encoded_image_string]" alt="Image">
</body>
</html>
Replace [base64_encoded_image_string]
with the actual base64 encoded string from Step 1.
Step 3: Set the email content type
When sending the email, set the Content-Type
header to text/html
to indicate that the email body is in HTML format.
Step 4: Send the email
Use your preferred SMTP library or tool to send the email. For example, in Python using the smtplib
library:
import smtplib
from email.mime.text import MIMEText
msg = MIMEText(open('email_body.html', 'r').read())
msg['Subject'] = 'Test Email with Image'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
server = smtplib.SMTP('smtp.example.com')
server.sendmail('[email protected]', '[email protected]', msg.as_string())
server.quit()
Make sure to replace the placeholders with your actual email credentials and settings.
Tips and Variations
- You can use other image formats like PNG or GIF by changing the
image/jpeg
part in thesrc
attribute toimage/png
orimage/gif
. - If you're using a templating engine like Jinja2 or Mustache, you can render the HTML template and include the base64 encoded image string.
- Some email clients may not support inline images or may display them as attachments. Be sure to test your email in different clients to ensure it works as expected.
