EmailBison offers two tools to help you manage which contacts should not receive emails: the Blacklist and the Unsubscribe List. While they may seem similar, they function differently and serve slightly different purposes depending on your workflow.
The Blacklist is used to block emails from being sent to certain email addresses or domains at the moment of sending.
You can still add blacklisted contacts to a campaign.
Before each email is sent, the system checks if the contact’s email address or domain appears on your blacklist.
If a match is found, the email will not be sent, and the sequence is stopped for that contact.
Blocking known bad or risky domains.
Avoiding outreach to competitors or internal domains.
Preventing delivery to unsubscribed contacts managed manually outside of Bison.
The Unsubscribe function operates at the contact or campaign level. It prevents contacts from being added to any campaign in the first place.
If a contact is unsubscribed, the platform will not allow you to add them to a campaign.
This check happens during list upload, import, or contact assignment.
The contact is excluded from all sequences by default.
Managing contacts who’ve requested not to be contacted again.
Avoiding accidental reactivation of cold leads.
Centralizing opt-outs across your system.
EmailBison does not automatically sync blacklist and unsubscribe actions.
If you add someone to your blacklist, they are not automatically unsubscribed (and vice versa). This is by design, so you can manage each list according to your specific workflows.
If your workflow requires both, you'll need to apply both actions manually.
