Both archiving and deleting an email or phone are soft operations. Neither one erases the underlying conversation history tied to that entry.
The key restriction
A primary email or phone cannot be archived or deleted while it's still primary. You need to designate another active entry as primary first, then the original becomes eligible.
Example: A candidate changes jobs and gets a new work email. Add the new email, mark it primary, and only then archive the old one — trying to archive it first will be blocked.
Things to know:
Hard delete is possible by clicking on the edit icon beside a number or email and deleting from the next modal as seen in the image below.
