Scans through your email account and find all the unsubscribe links in all your emails.

AutoUnsubscribe.py

#!/usr/bin/env python3

# Scans through your email account,
# find all the unsubscribe links in all your emails,
# and automatically opens them in a browser.

# This program will have to log in to your email provider's IMAP server
# and download all of your emails.
# You can use BeautifulSoup to check for any instance
# where the word unsubscribe occurs within an HTML link tag.

# Once you have a list of these URLs,
# you can use webbrowser.open() to
# automatically open all of these links in a browser.

# You'll still have to manually go through and
# complete any additional steps to unsubscribe yourself from these lists.
# In most case, this involves clicking a link to confirm.
