I would like to be able to easily check contacts with emails on hold designate other emails as primary, so the contacts continue receiving emails. I can make a profile to show primary and home, billing, other etc email addresses to quickly see which contacts have other email addresses. However, I can't figure out how to easily see if a contact has more than one home email address, as the search view only displays the first one. Is there any way to make this visible in a search view or even searchable?
I found a way to do this with the Data Processor extension, but it isn't pretty.
Use data sources email and contact in group (filter to a group you've created, perhaps with the mail bounce report), with match on contact ID = email contact. Fields: raw field value email, raw field value contact ID, raw field value email location type (optional).
Output a CSV and then you can find duplicate contact IDs with non-matching emails in this spreadsheet.
