Hi,
I have an email campaign which has been sent out but over 100,000 people had not been sent the email and marked as failed because there was too many connections to my ESP. Now because iv sent the same email campaign out to different lists im not able to do a re-send to the contact list that had the failed emails.
How can i do a re-send to the ones that failed?
