Copy a list of email addresses into the first column of this file. By pushing the button, all email addresses will be cleaned, formatted, and duplicates removed. The list will then be cleaned against all emails on the second tab.
The result is a list you have never emailed. The results are also automatically added to the second tab so that they won’t be used again in the future.
This will ensure that you never resend to any emails you scrape from any source.
