We were very excited to start using the new Constant Contact Sync feature, so we don't have to upload new lists all the time. Unfortunately, the feature doesn't sync spouse emails, which excludes almost half of our constituents from the process. The list feature has no column for spouse emails or any info other than their name. It basically makes the feature useless to us.
It seems like an oversight to me, and I hope it is resolved soon so we can start using the feature.
