  • 3How long will it take to receive my cleaned data once I upload it into Purelist?

    Purelist is a real-time, email processing platform. Depending on the size of your list and how many jobs are in front of you, normal turnaround time is only a matter of seconds or minutes, depending on the size of your list. For example, a list of 50,000 email addresses will take approximately 25 seconds, while a list of 1 million email addresses will take approximately 4 minutes to run.

  • 4What will my list look like when Purelist has finished cleaning it?

    You will receive back 2 lists. The first list will be all clean and usable email addresses. The second list will be all scrubbed email addresses we recommend you do not send emails to. Each list will contain email addresses only. You will also be able to view and download a detailed report for your Purelist order.

  • 5What do you do with my data after it has been cleaned and validated?

    We store all customer data on our secure, compliant internal storage server. After 5 days this data is truncated and destroyed. We save the report for viewing anytime through your personal account details page.

  • 6Is my data safe from being used by anyone other than me, the list owner?

    Yes, we use a PCI Compliant workflow with management and control of your data limited to our online processing system from start to finish. All customer provided email data is removed and deleted from our system within 120 hours of processing.

  • 7How can I be sure my data won’t be used by anyone other than me?

    There is a simple solution to be 100% positive your data is safe and unused by anyone else. Seed your data. Create a few new email addresses with ISPs such as; AOL, Yahoo, Gmail, etc. and add these new email addresses to the list you provide us and upload for cleaning. If you ever get an email to any of these newly created email addresses, you will know there is a problem. Make sure you never use these email addresses for anything else, as this will undermine their intended use.

  • 8If my database is collected and owned by me, why should I bother to clean it?

    Cleaning your email database or email list will protect your IP reputation; enable you to maintain good deliverability and keep your white listings in place. It will allow you to get better inbox deliverability with your email campaigns and avoid being blocked, black listed or shut down by your ISP or ESP.

  • 9Does cleaning an email list really help deliverability of my newsletters and marketing emails?
