Handling 3rd Party Suppression Files
Not sure if anyone has any suggestions on this, but we deal with a 3rd party advertiser who we send dedicated email campaigns for and they have a suppression file of about 1 million records. At our previous ESP we would just send the files over and they would be able to suppress them from our campaign. I'm not sure how that same scenario would work in Marketo as we don't want to upload these 1 million records to our instance. Any suggestions would be appreciated!
