Applies to all internal employees who manage prospect or customer mailing lists for a specific company within the Stochastic Marketing App.
The Company-Specific Do Not Mail Upload feature allows you to submit a list of addresses that should be excluded from mailings for a single company only.
When a file is uploaded, the system attempts to match the provided addresses to existing customer or prospect records for that company and updates their status to “Do Not Mail.”
⚠ Important: This process does not update the Global Do Not Mail list under Administration → Stochastic. The Global list blocks mailings across all companies, while this upload applies only to the company account you are working in.
Access to Hub+ with permissions to use the Stochastic Marketing App upload functions.
A properly formatted file (CSV or Excel) containing the following fields:
Name
Address
Address2 (if applicable)
City
State
Zip
Ensure your file contains only the required fields listed above.
Verify all addresses are accurate to avoid excluding the wrong records.
Save your file in CSV or Excel format.

If you want to add the matched addresses to the Do Not Mail list:

Confirm to return to the previous screen.
Data in the uploaded table cannot be edited within the system.
If incorrect data is uploaded, you must:
