Yes. ClaimWizard lets you store multiple email addresses for a contact.

In the contact fields, there is a primary email plus an additional Email 2 field (and multiple phone fields), so you can track multiple addresses for the same person without creating duplicate contacts. This is useful when a policyholder or attorney uses different emails for personal and business communication—both can live on the same contact record, even though you’ll typically choose one as the main address for outreach and archiving.
