Below is a detailed description of how our entire process works. There are 7 steps we use when cleaning and scrubbing email addresses.

  • 1Remove duplicates, improperly formatted email addresses and syntax errors.
  • 2Removal of “Role Account” emails, such as: sales@, support@, info@, etc.
  • 3Keyword Scrub – We remove words like spam, junk, abuse, etc. from the list of emails.
  • 4Bounce File Compare – We have a list of 100+ million hard bounces and we remove these emails from your list when we run a compare. This incudes emails which have sent a challenge response or requested removal.
  • 5Complainers File – We compare our complainers file to your list of emails and remove any matches. We also remove emails if they are a member of Spamcop. 
  • 6Domains – We run a compare and remove any spam seed, BOT, honeypot, black list or bogus emails/domains from your list of email address domains. The list we own and maintain is approximately 156,000+ domains.
  • 7Throwaway, disposable email addresses – We remove all temporary and junk collector email addresses. These email addresses are usually implemented for a one time use to sign up or to bypass providing a valid, primary email address.

Once your uploaded email list has been processed, you will be provided with a clean list, filtered list and report showing all of the details of your Purelist order.
