Note: ✅ Verify can accept CSV files up to 200mgs which can be a few million records. If your CSV file is larger than 200mgs, segment into smaller lists to upload individually.

Next, we will create a Verify tool account and upload your Sierra Interactive data.

Next, you will need to create an account on Verify to upload your Sierra Interactive list for the DNC scan. Here's the step-by-step guide.

  • Note: when you export the CSV file it will be named: verify_contacts_(your list name).csv

Next, you are ready to import the DNC scrubbed file back into your Sierra Interactive account and use Tags to filter the scrubbed contacts in your CRM.

Sierra Interactive has a cap of importing 5,000 records at a time from a CSV file. You may need to break-up the Verify scrubbed file into smaller groups which we will show you next.

Verify CSV Export File Headers & Filed Information

Here are the basic name, phone, email and address fields.


These fields will map directly to your Sierra Interactive site via the Import wizard.

Verify Phone Scrub Fields

Below is the two primary fields of the verify phone scrub results with possible outcomes.

  • Phone DNC Registered: Yes = Listed on DNC, No = Not listed

  • Phone Deactivated: Yes = reported deactivated or reassigned in last 6 months, No = Not deactivated in last 6 months

You'll likely want to be able to filter your Sierra Interactive contacts by these primary filters as they indicate if the phone number is listed on the National Do Not Call registry list.

Verify Email Scrub Field Headers

These are the primary email scrub results with the headers. You can map all of this data into a note in Sierra or create custom tags using the field data.


We recommend filtering by the following:

  • Email Deliverability: Deliverable = valid email, Undeliverable = bad email

  • Email Score: numeric value. Higher is better quality email. Suggest 70 or higher.

Now that you Sierra Interactive leads are scrubbed against the DNC and emails verified, you can import the results back into using the following steps.


We have also created a Zapier workflow to easily update your leads using the Verify CSV file if you wish to skip the following step.

3. Importing Verify DNC Scrub Contacts Into Sierra Interactive

To import contacts from a CSV file into Sierra Interactive without creating duplicates and to assign tags, follow these steps:

  1. Prepare Your Verify DNC Scrubbed CSV File for Sierra Interactive:

    • Sierra Interactive has a maximum record import size of 5,000 records.

    • You may need to filter the scrubbed CSV file into smaller segmented files as indicated above.

    • Add Tags: Include a column for tags in your CSV. Assign relevant tags to each contact, ensuring these tags exist in Sierra Interactive for easy segmentation.

    Recommend CSV Lists to Import to Sierra Interactive

    Suggested Email Only Contacts: Filter your CSV file using the filter below to import that you should follow-up with only via email since contacts have phone numbers that are registered on the national Do Not Call registry or recently Deactivated and Reassigned but have a valid email address.

    • DNC Registered = Yes + Email Deliverability = Deliverable; this is a group of contacts that will you want to email only since the phone numbers is registered on the DNC with valid email addresses.

    • DNC Registered = No + Phone Deactivated = Yes + Email Deliverablity = Deliverable; this are phone numbers that may be deactivated and reassigned to a different person with deliverable email address.


    Likely Good Contacts: This filtered CSV file would be phone is not on DNC, not deactivated and the email is valid.

    • DNC Registered = No + Phone Deactivated = No + Email Deliverability = Deliverable; this would be your contacts NOT on the DNC, phones have not been deactivated or reassigned in last 6 months with valid email addresses.

    All Bad Emails: This filtered list would be all contacts with bad email address that
    are undeliverable. You'll want to tag these to prevent unnecessary bounce rates that will hurt you email reputation.

    • Email Deliverablity = Undeliverable; this are all bad email addresses that will bounce. You should avoid emailing this addresses. When you import these, add a tag like Bad Email to segment your contacts.


    Pro Tip: Use ChatGPT to segment your CSV lists easily and export as CSV files. Always check the file to make sure it looks correct.

    Remember max list import size into Sierra Interactive is 5,000 records. Get creative on your imports and tagging.

    You can also include all of the phone data and or the email data as a Note when importing the contact records.

    Click Save and Import

    Next, if you segmented specific list, you can add one or more tags based on the specific list you imported.

    Next, we are re-importing all of the leads that originally came from your Sierra Interactive account. These will all be considered Duplicates which is okay. Here's how to handle those files.

  5. Manage Duplicate Contacts:

    • Sierra Interactive identifies duplicates using email addresses and phone numbers.

    • When duplicate leads are imported, no existing contact data or agent assignments will be changed.

    • Additional contact information (such as secondary phone or secondary email) will be added when not already present.

    • Notes, tags, and other related items will also be added to the existing lead history when available.

    • If duplicates are detected, Sierra Interactive will prompt you to merge contacts or skip duplicates.

    • Select Import Duplicates to merge the contacts.


  6. Complete the Import:

    • After verifying all fields are correctly mapped.

    • Click Save and Import to initiate the upload.

    • Once the import is complete, confirm that contacts have been added without duplication and that tags are correctly applied.


      Note: You may need to repeat the above steps for each list depending on the size of your list, since max import size if 5,000 records.

  7. Reactivate Automations:

    • After confirming the successful import of all your Verify dnc scrubbed contacts, reactivate any automations that were previously disabled.

By following these steps, you can effectively import contacts into Sierra Interactive, avoid duplicates, and ensure proper tag assignment and segment your contact lists appropriately.
