How do I block emails from receiving my message based on a campaign or based on a list selection?
There is a way to send an email message to only a portion of a list. You can use a suppression list to block certain emails For example if you have 20 email addresses you don’t want to email, you can add these to a suppression list file and select suppression list this during campaign setup. This will send to everyone on the list except anyone listed on the suppression file. Basically what happens is our system cross references your mailing list with the suppression list and doesn't mail those email addresses on the suppression list.
