checking against negative list
We allow multiple records for leads for business reasons I won't get into. Changing this righ tnow is not an option. This means a lead can convert under one record while they could possibly have other records that indicate they have not converted.
I'd like to put converted leads in a smart list - easily done. Next, I would like any lead campaigns to check the email addresses in the smart list and remove leads from the campaign if their email address appears in the smart list.
Is this possible?
