Yet another mail merge unsubscribe
The never-ending battle against unwanted emails!
Here's a sample code for a mail merge unsubscribe link in Python using the pandas
library:
Assumptions:
- You have a CSV file containing your email list, with columns for
email
andunsubscribe_token
(a unique token for each subscriber). - You have a mail merge template (e.g., HTML file) that includes a link to this script.
Code:
import pandas as pd
import smtplib
from email.mime.text import MIMEText
# Load the email list from the CSV file
emails = pd.read_csv('email_list.csv')
# Define the mail merge template (HTML file)
template_file = 'mail_merge_template.html'
# Define the unsubscribe link URL
unsubscribe_url = 'https://example.com/unsubscribe'
# Create a dictionary to store the unsubscribe tokens
unsubscribe_tokens = {}
# Loop through each email in the list
for index, row in emails.iterrows():
email = row['email']
unsubscribe_token = row['unsubscribe_token']
# Create a unique unsubscribe link for each email
unsubscribe_link = f'{unsubscribe_url}?token={unsubscribe_token}'
# Replace the unsubscribe link in the mail merge template
with open(template_file, 'r') as f:
template = f.read()
template = template.replace('{{ unsubscribe_link }}', unsubscribe_link)
# Send the email
msg = MIMEText(template)
msg['Subject'] = 'Your Mail Merge Email'
msg['From'] = 'Your Email Address'
msg['To'] = email
# Send the email using your preferred email service (e.g., Gmail)
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login('your_email_address', 'your_email_password')
server.sendmail('your_email_address', email, msg.as_string())
server.quit()
# Store the unsubscribe token in the dictionary
unsubscribe_tokens[email] = unsubscribe_token
# Save the unsubscribe tokens to a file (e.g., for later reference)
pd.DataFrame(unsubscribe_tokens).to_csv('unsubscribe_tokens.csv', index=False)
How it works:
- The script loads the email list from a CSV file and defines the mail merge template (HTML file) and unsubscribe link URL.
- It creates a dictionary to store the unsubscribe tokens, which are unique for each email.
- The script loops through each email in the list and creates a unique unsubscribe link for each email by appending the unsubscribe token to the URL.
- It replaces the unsubscribe link in the mail merge template with the unique link for each email.
- The script sends the email using your preferred email service (e.g., Gmail).
- It stores the unsubscribe token in the dictionary for later reference.
- Finally, it saves the unsubscribe tokens to a file (e.g., for later reference).
Tips:
- Make sure to use a secure method to store and transmit the unsubscribe tokens, such as using a secure token service or encrypting the tokens.
- Consider implementing a double-opt-in process to ensure that subscribers confirm their email address before receiving emails.
- Always include a clear and easy-to-use unsubscribe link in your emails, and make sure it's functional and easy to use.
