At my previous company, they created a group on our (Salesforce Community) customer portal, invited customers within the segment that were targeted for the pooled model to join that group and had the Pooled CSMs work with customers within that group. They had a schedule where each CSM would proactively share useful tips and tricks, etc and the contacts could reach out via the Group and the CSMs would rotate shifts monitoring the queue to provide assistance and guidance.
Thanks @darkknight! so the customers knew they had a team supporting them and not just one exclusive CSM, right?
@andorfuhrer basically yes they did.
