Upload a Suppression List

To avoid paying for contacts you already have, you will need to manually load a CSV file of email addresses so that we don’t collect them, as well.

Suppression lists loaded as a CSV file are converted into encoded MD5s for security reasons. We do not use, share, or resell this data for any purpose other than to prevent users from collecting and paying for contacts they already have.

To upload a Suppression List, click on Suppression Lists in the left-hand navigation.

Here are the file requirements for upload:

  • Your file should only contain ONE column, labeled “email”.
  • You’ll also need to save it as an Excel .CSV file.
  • Maximum file size is 100MB. If your file is larger than this, split it up into several smaller files.

Once the file has uploaded, you will see a green box in the top right corner that says your file has been uploaded and is in the queue to be processed. Once that’s complete, you’ll see the stored file listed under the corresponding date:

Remove the integration

1. To remove the integration, click Integrations > Dots Remove.

To access all of your sync history, click View Full History under Sync Summary. If there’s a failure, it will show the email address, what type of failure has occurred under ESP Feedback, and the date and time of the failure.
