Ubico lets you blacklist domains to prevent reaching out to current opportunities or existing customers.
Step 1: Navigate to your account settings.
Step 2: Add domains to your blacklist by entering it manually or copy-paste it to the text area below. If you're putting more than one domain make sure to separate it with comma, space or new line.
Once saved, these domains will not be contacted and will be used as a suppression list when searching and collecting data for your contacts.
