After you place your order online, we clean your list one final time. This final cleansing & verification process takes about 2-4 hrs during normal business hours. This process ensures that you only receive the most valid, up-to-date email addresses. After your list goes through this final cleansing and verification process, we will email you your cleaned-up list as an excel/.csv file. If we remove any email addresses, we will refund you back for the difference. On average, we remove 15-40% of the emails on your list.
