I want to assess an email campaign that is made up of many emails to determine which contacts are my most loyal. I want to maintain a Segment of those people so I can create campaigns just for them, and to conduct other kinds of follow up. I cannot see how to do that without a lot of effort.
You would want to create a segment based on Response History and search for contacts who have opened or clicked links in your campaigns. If a contact is opening your campaigns or even better clicking any links in your campaigns, these are your most loyal contacts. Head to your Audience page and click on the Segments tab. You can create the segment searching for contacts from your entire audience who have opened and/or clicked or you can specify an audience group as well as a particular mailing.
Take a look here for our Segments support resource where we discuss the different segments that you can create. We also have some great services available to you where you will work with a Service Specialist and they will help with List Segmentation to meet your goals. If you are interested in speaking with a Service Specialists to discuss some services that may be a great fit for you, give me a shout and I am happy to get you connected.
Feel free to reach out with any questions or if there is anything else I can do to help!
