Here in this blog, I’ll be discussing with you a way in which you can send bulk mailers to people using Python via Linux terminal
We will leverage the power of the ‘smtplib’ module, which is a part of the Python Standard Library, to establish a connection with an email server and send emails.
I have divided the procedure into three simple steps as follows:
Step 1: Setting Up a Virtual Environment
This is optional, but If you setup a virtual environment, it will be easier for you to access the features and leverage the module.
Check whether your system has any updates using
If you haven’t installed Python 3, then it’s time that you do so.
then install virtualenv using ‘pip3 install virtualenv.
Now Create a Virtual Environment with ‘virtualenv email_project’ , and to activate the virtual environment, use ‘source email_project/bin/activate’.
Step 2: Installing Required Libraries
In this project, we’ll need the ‘smtplib’ module for sending emails and the email module for creating email messages. These modules are part of the Python Standard Library, so no additional installation is required.
Step 3: Writing Python Code to Send Bulk Emails Now, let’s write the Python code to send bulk emails to everyone. We’ll assume you have a list of email addresses in a file named recipients.txt, and the content of the email is stored in a file named email_content.txt.
Create a new Python file, for example,send_bulk_emails.py, and open it using your favorite text editor. Then, add the following code:
Here you have to replace smtp_host, user name, and password as per your email server host; for me, it was ‘smtp.gmail.com’.
Also, you have to mention all the mail IDs in files ‘recipients.txt, to which the mailer will be sent, and ‘email_content.txt, which will contain all the content of the mail.
Step 3: Run the Python script as ‘python3 send_bulk_emails.py’.
Warning: I won’t suggest using this method for daily usage or for things where privacy is a concern.
If you’re using Gmail as the SMTP server, you might need to enable “Allow less secure apps” in your Google account settings. However, keep in mind that this is not recommended for production use, and it’s better to use an email server that supports secure authentication mechanisms.
