A suppression list is a list of email addresses of users you want unsubscribed or blacklisted. Adopia allows you to load your suppression list(s), to prevent these blacklisted users from re-subscribing.
In your Adopia account, click Manage Suppression.
Under Manage Suppressions click Add New Suppression List. In the Add Mask(s) in Suppression List pop up window enter your
Suppression List Name. Choose between Import from file, where you are able to load your suppression list file or select
Enter Contacts in a box where you can enter the suppression contacts manually.
Click Upload when finished.
