By using the blacklist you make sure that hubsell does not collect prospects from specific domains. You can either add those each on its own to the blacklist
or add multiple domains by using the "bulk add" function.
If you want to avoid reaching out to single prospects, maybe for example because you already cold called them, you can do as follows:
Go to Data select the prospect and mark it as "unsubscribe". You will now no longer be able to send mailings by accident or by choice.
You have now successfully created your blacklist and go over to the next step, which is 'how to integrate your CRM with hubsell.'
