How I Automated Sending Bulk Emails Without Any Cost

Lots of companies, just like mine, really depend on talking to people well to get their products or services out there. Good communication is the key to growing. Emailing folks, it’s still a super way to reach them, whether it’s marketing stuff, building’ relationships, or teaching folks stuff. But, you know, sending hundreds or thousands of emails one at a time is a real pain and easy to mess up. That’s where making it automatic comes in handy! Let’s look at how to send out lots of emails automatically with Python, which is a real useful computer language.

What’s Bulk Email Automation?

Bulk email automation, it’s just sending a whole bunch of emails to different people without having to do much yourself. Marketing campaigns, keeping customers happy, or finding new leads, they all use it a lot. Businesses save time, mess up less, and make sure they’re saying the same thing to everyone when they make email in automatic. Recent AI Market will not tell you this.

Python is a good language ’cause it’s easy to use and got real powerful tools. People use it for all sorts of stuff like looking at data, making websites, and making things automatic. Python’s great for sending lots of emails too. The reason I am saying this:

• Easy to Learn: Python’s language is not hard, so writing’ and understanding’ code ain’t that bad. It took me just 3 months to start working with python from scratch.
• Lots of Tools: Python has tools called libraries, like smtplib for sending emails and csv for working with lists, so making things automatic is easier.
• Can Handle Big Data: Python can work with big lists of people, so it’s good for sending emails to thousands of clients across the globe.
• You Can Change It: Python lets you change how the emails look, when they go out, and keep track of ’em to fit what you need.

How to Automate Email Outreach with Python, Step-by-Step

We’ll walk you through making’ a Python code for sending lots of emails automatically. We’ll use the code and talk about how it works.

Gettin’ Ready

Make sure you have Python on your computer. If not, go get it from the Python website. Then, use a code editor like VS Code or PyCharm to write your code.

Configuration

The first part of the code sets up the configuration for sending emails.

SMTP_SERVER = # Replace with your SMTP server'
SMTP_PORT = # Use 465 for SSL or 587 for starttls  
SMTP_USERNAME = ‘# Replace with your email’
SMTP_PASSWORD =  ‘# Replace with your password’
EMAIL_SUBJECT = '# Replace with your subject line”
EMAIL_BODY = “# Replace with your email body”

Reading Emails from a CSV File

The code looks at a list of email addresses, checks if they’re good, and sends an email to each person. Here’s what’s important in the code:

Reading Emails: The read_emails_from_csv reads email addresses from a file and skips the ones that say “sent” so you don’t send ’em twice.

def read_emails_from_csv(file_path):
    """Read email addresses from a CSV file, excluding those already marked as 'sent'."""
    emails = []
    with open(file_path, newline='') as csvfile:
        reader = csv.reader(csvfile)
        for row in reader:
            if len(row) > 0:
                email = row[0].strip()
                if len(row) < 2 or row[1].strip().lower() != 'sent':  # Check if the email is not marked as 'sent'
                    emails.append(email)
    return emails

Validating Email Addresses

Checking Emails: The validate_email makes sure the email address looks right using a special pattern.

def validate_email(email):
    """Validate email address using regex."""
    return re.match(EMAIL_REGEX, email) is not None

Sending Emails

Sending Emails: The send_email uses the smtplib tool to send the emails. It also waits a little bit, like 30 seconds to 2 minutes, so your emails don’t look like spam to the receiver’s server.

def send_email(to_email):
    """Send an email to the specified address."""
    msg = MIMEText(EMAIL_BODY, 'html')  # Set the content type to 'html'
    msg['Subject'] = EMAIL_SUBJECT
    msg['From'] = f'{FROM_NAME} <{FROM_EMAIL}>'
    msg['To'] = to_email

    try:
        with smtplib.SMTP_SSL(SMTP_SERVER, SMTP_PORT) as server:
            server.set_debuglevel(1)  # Enable debugging
            server.login(SMTP_USERNAME, SMTP_PASSWORD)
            server.sendmail(FROM_EMAIL, to_email, msg.as_string())
        print(f"Email sent to {to_email}")
        return True
    except Exception as e:
        print(f"Failed to send email to {to_email}: {e}")
        return False

Explanation:

This function constructs the email message, including the subject, body, and sender information. It connects to the SMTP server using SSL for secure communication, logs in using your email credentials, and sends the email. The MIMEText object allows for HTML formatting, making the email more visually appealing.

Marking as Sent

The mark_email_as_sent changes the list to say which emails have been sent so you know you’re done. After sending an email, the script updates the CSV file to mark it as ‘sent’. This keeps track of which emails have been successfully delivered.

def mark_email_as_sent(file_path, email):
    """Mark the email as sent in the CSV file."""
    rows = []
    email_found = False
    with open(file_path, newline='') as csvfile:
        reader = csv.reader(csvfile)
        for row in reader:
            if len(row) > 0 and row[0].strip() == email:
                row.append('sent')
                email_found = True
            rows.append(row)

    if email_found:
        with open(file_path, 'w', newline='') as csvfile:
            writer = csv.writer(csvfile)
            writer.writerows(rows)

Main Function

The main function is the entry point of the script. It coordinates all the functions, reads the email list, processes each email, and handles delays to prevent being flagged as spam.

def main():
    file_path = 'emails.csv'  # Path to your CSV file
    emails = read_emails_from_csv(file_path)

    for email in emails:
        if validate_email(email):
            if send_email(email):
                mark_email_as_sent(file_path, email)
                # Random delay between 30 seconds to 2 minutes
                delay = random.uniform(30, 120)
                print(f"Waiting for {delay:.2f} seconds...")
                time.sleep(delay)
        else:
            print(f"Invalid email address: {email}")

if __name__ == '__main__':
    main()

How can you also use the code?

Put in your email server details, username, and password where it says SMTP_SERVER, SMTP_USERNAME, and SMTP_PASSWORD.

If you use Gmail, for example, the server is smtp.gmail.com and the port is 465.

Change the EMAIL_SUBJECT and EMAIL_BODY to what you want your email to say. You can use HTML to make it look nice.

Once you set it up, you can run the code with Python. It’ll read the email list, check each address, send the email, and mark it as sent. It does all this by itself, so sending lots of emails is easy.

Being Ethical

When sending lots of emails, make sure you’re doin’ it right. Make sure you are only sending emails to those people who said it was okay.

• Use Clear Subjects: Make the subject of the email clear so it doesn’t look like spam.
• Personalize Your Email: Make the emails personal so people pay attention.
• Option to Unsubscribe: Let people get off your email list if they want to, it’s the law.

Sending emails automatically with Python is a great way to make your communication easier and save time. By using Python’s tools and being ethical, you can send personalized emails to your people without spending’ all day doin’ it. If you own a small business or work in marketing, this can really help you get to your goals.
