Suppression files contain the email addresses of the contacts you want to exclude from your Data.com Connect purchases or exports.
The file must be in CSV (comma-separated values) format, with the filename extension of .csv. Files in CSV format store data in structured lists, making it easy to import and export data across applications.
We recommend using a spreadsheet program such as Microsoft Excel to create a suppression file.
To create a suppression file
Enter email addresses of contacts into the spreadsheet, following this example:
The first row in the file must say email, with one email address per row. You can add up to 200,000 contacts per file, with a maximum file size of 10MB.
If you already have a list of email addresses to exclude you can import the addresses, or copy them and paste them into the spreadsheet.
Use Save As to name your spreadsheet, using the .csv file extension— Connect won't accept your file if it isn't in .csv format.
In this example, an Excel file is saved as MySuppressionList.csv:
Your suppression file is ready to upload into Connect.
