Do Not Mail (DNM) List Scrubbing Process
To help maintain the accuracy of your Do Not Mail (DNM) list, we organize submitted records into four categories during processing:
NEW DNM Names to Scrub
This sheet is where you should add any new names and addresses you would like suppressed from future mailings.
After processing, records will be moved from this sheet into one of the categories below based on the validation results.
Verified Addresses
These are addresses that were successfully validated through Smarty address verification and were properly suppressed from your mailing list.
Invalid Addresses
These records could not be validated and returned one of the following results:
No Match — The address could not be verified. Common reasons include:
Incorrect house number
Misspelled street name
Missing street type (Rd, Ave, St, etc.)
Missing city, state, or ZIP code
Incomplete address information
Match – Non-Postal — The address exists, but USPS does not deliver mail to that location.
If you would like to correct or update any invalid addresses, you may add the updated information back into the NEW DNM Names to Scrub sheet for processing on your next order.
Missing / Incomplete
These records do not contain enough address information to process suppression. Examples include:
Name only
City, State, ZIP only
Missing street address information
You are welcome to update and resubmit these records through the NEW DNM Names to Scrub sheet.
Additional Information
Your DNM spreadsheet is yours to maintain and use going forward.
Due to the high volume of orders we process, we are unable to research or manually correct invalid or incomplete addresses, especially on large lists.
A link to your company’s DNM Google Sheet can be found in HubSpot under the Success Coach section on your company page.
If you have any questions about the process, please feel free to reach out to our team.
