How to send attachments using SMTP in python?

To send email attachments using the SMTP protocol in Python, you can use the smtplib library for sending emails and the email library for composing email messages with attachments. Here's a step-by-step guide on how to send email attachments using SMTP:

  1. Import Required Libraries: Start by importing the necessary libraries:

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

  2. Create an SMTP Connection: Set up an SMTP server connection. You'll need to provide your email server's hostname, port, and authentication credentials (username and password).

    smtp_server = 'your_smtp_server.com' smtp_port = 587 # Typically 587 for TLS, 465 for SSL smtp_username = 'your_username' smtp_password = 'your_password' server = smtplib.SMTP(smtp_server, smtp_port) server.starttls() # Use TLS encryption server.login(smtp_username, smtp_password)

  3. Create the Email Message: Use the MIMEMultipart class to create an email message with attachments:

    msg = MIMEMultipart() msg['From'] = 'your_email@gmail.com' msg['To'] = 'recipient@example.com' msg['Subject'] = 'Email Subject'

  4. Add Text and Attachments to the Email: You can add the email body text and attachments using MIMEText and MIMEApplication classes:

    body = 'This is the email body.' msg.attach(MIMEText(body, 'plain')) # Add an attachment with open('attachment.pdf', 'rb') as attachment_file: attachment = MIMEApplication(attachment_file.read(), Name='attachment.pdf') attachment['Content-Disposition'] = f'attachment; filename=attachment.pdf' msg.attach(attachment)

    Replace 'attachment.pdf' with the actual path to your attachment file.

  5. Send the Email: Send the email with the attached file using the sendmail() method:

    server.sendmail('your_email@gmail.com', 'recipient@example.com', msg.as_string())

  6. Close the SMTP Connection: After sending the email, close the SMTP connection:

    server.quit()

Here's the complete code for sending an email with an attachment:

import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.application import MIMEApplication smtp_server = 'your_smtp_server.com' smtp_port = 587 # Typically 587 for TLS, 465 for SSL smtp_username = 'your_username' smtp_password = 'your_password' server = smtplib.SMTP(smtp_server, smtp_port) server.starttls() server.login(smtp_username, smtp_password) msg = MIMEMultipart() msg['From'] = 'your_email@gmail.com' msg['To'] = 'recipient@example.com' msg['Subject'] = 'Email Subject' body = 'This is the email body.' msg.attach(MIMEText(body, 'plain')) with open('attachment.pdf', 'rb') as attachment_file: attachment = MIMEApplication(attachment_file.read(), Name='attachment.pdf') attachment['Content-Disposition'] = f'attachment; filename=attachment.pdf' msg.attach(attachment) server.sendmail('your_email@gmail.com', 'recipient@example.com', msg.as_string()) server.quit()

Make sure to replace 'your_smtp_server.com', 'your_username', 'your_password', 'your_email@gmail.com', 'recipient@example.com', 'Email Subject', and 'attachment.pdf' with your SMTP server details, email addresses, subject, and attachment file path.

    • Description: This query seeks guidance on sending email attachments via Python's SMTP library. Attaching files to emails is a common requirement in automated email workflows.
    • Code Implementation:
      import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.base import MIMEBase from email import encoders def send_email_with_attachment(sender_email, receiver_email, subject, body, attachment_path, smtp_server, smtp_port, smtp_username, smtp_password): message = MIMEMultipart() message['From'] = sender_email message['To'] = receiver_email message['Subject'] = subject message.attach(MIMEText(body, 'plain')) with open(attachment_path, 'rb') as attachment: part = MIMEBase('application', 'octet-stream') part.set_payload(attachment.read()) encoders.encode_base64(part) part.add_header('Content-Disposition', f"attachment; filename= {attachment_path}") message.attach(part) smtp_connection = smtplib.SMTP_SSL(smtp_server, smtp_port) smtp_connection.login(smtp_username, smtp_password) smtp_connection.sendmail(sender_email, receiver_email, message.as_string()) smtp_connection.quit() # Example usage: sender_email = "your_email@gmail.com" receiver_email = "recipient_email@example.com" subject = "Email with Attachment" body = "Hello, please find the attached file." attachment_path = "path/to/attachment.txt" smtp_server = "smtp.gmail.com" smtp_port = 465 smtp_username = "your_email@gmail.com" smtp_password = "your_password" send_email_with_attachment(sender_email, receiver_email, subject, body, attachment_path, smtp_server, smtp_port, smtp_username, smtp_password)
