Multiple campaigns in SFDC
We have a need to send out an email twice a month to a group of people, but the group itself changes based on whether or not they qualify for the smart list criteria at the time of the schedule. The challenge is that members can sometimes and often do overlap. So for example John Doe may be included in email send #1 and #4, but not #2, and so on. We essentially want to treat each email send as it's own campaign in Salesforce, but are having challenges trying to design.
Maybe to say another way, we could create/clone a Program in Marketo and a Campaign in Salesforce manually twice a month for a total of 24 during the year, but there would seem to be a better way. And we have many more campaigns like this, so relying on any manual steps is unrealistic.
Thanks in advance for any ideas/advice!
