Hi, I am searching for the best practice in RE, for a very common problem: send marketing emails to major donors, but exclude them from fundraising emails. We are recoding our usage of “Do not contact” solicitation code to specifically mark those people who asked us not to be contacted. However, there is the subset of people what wish to stay in touch with the organisation but to which we do not want to send small giving requests. I do not want to introduce yet an extra solicitation code and we believe this will best achieved with a dynamic exclusion list of some sort. What criteria should I use to flag to our data selection team “Exclude this person from next fundraising”? Again, I could use a combo of constituent codes, but it is getting very messy. A dynamic flag to switch on and off could be easily used to re-adjourn the exclusion list before the next fundraising ask is sent. Has anybody solved this common problem? If so, how? Many thanks for your help Nicoletta
