This video explains how to upload and manage global suppression records:
What the Global Suppression List Does
Use this feature to prevent Opta from accepting:
Users on a Do Not Contact list
Existing customers or subscribers already in your database
Duplicate or non-compliant records
The suppression list applies across all campaigns in your account.
Supported Formats
You can suppress records by:
Email
Phone number
IP address
Opta supports:
Plain text values (e.g., [email protected])
MD5 hashed values (halves only, no salts)
Download a sample file directly from the Suppression page to see formatting requirements for each field type.
How to Upload Suppression Records
Go to Campaigns > Suppression
Choose the suppression type (Email, Phone, IP)
Select the format (Plain Text or MD5)
Upload your file
Confirm successful upload—suppressed record count will update
Once uploaded, those records will be blocked across all campaigns. You can download the active suppression list at any time to share with partners.
Summary
The global suppression list is a simple but powerful compliance tool. It lets you centralize suppression and enforce rules across your entire Opta environment—no need to manage it campaign by campaign.
