Auto-detect and delete duplicate emails

To auto-detect and delete duplicate emails, you can use a script or programmatic method depending on where your emails are stored (e.g., in a database, spreadsheet, or email client). Here’s a general solution in Python using a list of emails:

Python Script to Detect and Delete Duplicate Emails

python
CopyEdit
def remove_duplicate_emails(email_list):
    # Convert to lowercase for case-insensitive comparison
    unique_emails = list(set(email.lower().strip() for email in email_list))
    return unique_emails

# Example usage
emails = [
    "user@example.com",
    "User@example.com ",
    "admin@example.com",
    "test@example.com",
    "user@example.com"
]

cleaned_emails = remove_duplicate_emails(emails)
print("Cleaned Emails:")
print(cleaned_emails)

If you’re using:

Excel or Google Sheets:

Use the Remove Duplicates feature:

• Select the email column.

• Go to Data > Remove Duplicates.

Gmail (using filters or Google Apps Script):

You can use Google Apps Script to scan Gmail threads and delete duplicates by checking subject/content/sender similarities.

Database (SQL example):

If emails are stored in a SQL database:

sql
CopyEdit
DELETE FROM email_table
WHERE id NOT IN (
    SELECT MIN(id)
    FROM email_table
    GROUP BY LOWER(TRIM(email))
);

Let me know where your emails are stored for a more tailored solution.
