From my experience, this is honestly the longest burning fire for many customers, mostly because Braze does a good job de-duping email sends, so it's "might" be okay to have multiple user profiles with the same email address.
However, to clean up your user profiles, you'd have to use the users/identify API endpoint or delete the abandoned profile through the Delete endpoint.
There's definitely way more details on this topic, but leaving this response short and sweet until further asked!
