pythonmassmailer

pythonmassmailer is a very simple multithreaded mass emailing python script that uses smtplib.SMTP class. I tested it with 400 threads at a time and it sent 1000s of emails within few seconds using few (but working) SMTP servers.

HOW IT IS DIFFERENT

• It is multithreaded and can execute any number of threads configured in the script
• You can use unlimited number of SMTP servers at the same time
• It uses SMTP server(s) efficiently so they are not overloaded
• 10K emails can be sent without any problem using few SMTP servers

PREREQUISITES

if you get error like "socks" module not found then please install PySocks using

pip install PySocks

SMTP SERVERS and RECIPIENTS EMAIL ADDRESSES

• SMTP servers must be listed in smtps.txt file. Each line in smtps.txt file is a smtp server in following format ip_address:port,email_address,password,1(0 for no authentication)

• Recipients email addresses must be listed in emails.txt file. Each line in emails.txt is a recipient email address

PROXY SERVERS

• Proxy servers must be listed in proxies.txt file. Each line in proxies.txt file is a proxy server in following format ip_address:port,proxy_type(socks4,socks5,http)

EXAMPLE: 123.456.789.1:1080,socks5

ENABLE/DISABLE PROXY SUPPORT

• You can change sendWithProxy of class MassMailerConfig in massmailerhelper.py file to toggle the proxy support. True = use proxy False = dont use proxy

ADDING ATTACHMENT(S)

• You can add attachment to individual EmailToSend objects using their Attachments list property
• testmailer.py demonstrates how to use that

RUNNING THE SCRIPT

• After you have setup your SMTP servers in smtps.txt and recipients in emails.txt then you can run the script like this:

  python massmailer.py

CHANGING SUBJECT and BODY

• You can change values for subject and body inside load_config procedure in massmailerhelper.py. Following lines will require modification to change subject and body

  config.subject="this will be your subject"

  config.body="This will be the email body" #you can use HTML in body

CHANGING OTHER VARIABLES

• You can change values like number of threads to use, maximum number of email to send, sender name etc inside load_config procedure in massmailerhelper.py. For example if you want to set number of threads to 500 then you can set this line inside load_config procedure

  config.totalThreads=100

FUTURE PLANS

• SSL support
