This example shows how to send an email with an attachment in Python, with the attachment being read from a file from the filesystem:
#!/usr/bin/env python3 import smtplib import mimetypes from email.message import EmailMessage # Create message and set text content msg = EmailMessage() msg['Subject'] = 'This email contains an attachment' msg['From'] = '[email protected]' msg['To'] = '[email protected]' # Set text content msg.set_content('Please see attached file') def attach_file_to_email(email, filename): """Attach a file identified by filename, to an email message""" with open(filename, 'rb') as fp: file_data = fp.read() maintype, _, subtype = (mimetypes.guess_type(filename)[0] or 'application/octet-stream').partition("/") email.add_attachment(file_data, maintype=maintype, subtype=subtype, filename=filename) # Attach files attach_file_to_email(msg, "myfile.pdf") def send_mail_smtp(mail, host, username, password): s = smtplib.SMTP(host) s.starttls() s.login(username, password) s.send_message(mail) s.quit() send_mail_smtp(msg, 'smtp.my-domain.com', '[email protected]', 'sae7ooka0S')
The utility functions in this code are:
import smtplib import mimetypes def attach_file_to_email(email, filename): """Attach a file identified by filename, to an email message""" with open(filename, 'rb') as fp: file_data = fp.read() maintype, _, subtype = (mimetypes.guess_type(filename)[0] or 'application/octet-stream').partition("/") email.add_attachment(file_data, maintype=maintype, subtype=subtype, filename=filename) def send_mail_smtp(mail, host, username, password): s = smtplib.SMTP(host) s.starttls() s.login(username, password) s.send_message(mail) s.quit()
Initialize your email like this:
# Create message and set text content msg = EmailMessage() msg['Subject'] = 'This email contains an attachment' msg['From'] = '[email protected]' msg['To'] = '[email protected]' # Set text content msg.set_content('Please see attached file')
and then attach the file like this:
attach_file_to_email(msg, "myfile.pdf")
and send the email using
send_mail_smtp(msg, 'smtp.my-domain.com', '[email protected]', 'sae7ooka0S')
