Should I Clean First/Last Names Before Using Waterfall Enrichment for Email Addresses?

When using waterfall enrichment for email address, you have to provide things like first, last and company website. Should we clean the first / last name first? For example, we're pulling this data from LinkedIn so we have names like: John Doe, MBA Dr. John Doe etc, When the name is passed to the enrichment it's passed as Doe, MBA (last name) or Dr. John (first name). Sometime's it's returning the right email address, so I'm not sure if I should clean it or not.
