Sending Email with Python¶

June 6^th, 2022

Before you send email from pyhon script, you should know that sending by email means you have to enter your credentials into your python script. So that means its' dangerous right? luckily google had taken care of that problem, google gives access to get login without actual password, so google will just make generated password in certain activity(email/callendar/etc).

so to make it clear, you can check how to make grant app google credential in this link (use it wisely, make sure no one knows your generated password)

after waching that video, you will have 16 generated password that you can use to login from your app

email = 'your_email@gmail.com'
password = '<16_generated_password>'
sender = email
targets = ['receiver@gmail.com']

msg = MIMEText('Hi, how are you today?')
msg['Subject'] = 'Hello'
msg['From'] = sender
msg['To'] = ', '.join(targets)

server = smtplib.SMTP_SSL(smtp_ssl_host, smtp_ssl_port)
server.login(email, password)
server.sendmail(sender, targets, msg.as_string())
server.quit()

    file_att = MIMEText(f.read())
# filepath_img = './file.jpg'

    # file_att = MIMEImage(f.read())

file_att.add_header('Content-Disposition',
            'attachment',
            filename=os.path.basename(filepath))
msg.attach(file_att)
