Currently, you cannot change vendor or client emails once they have been added to Hopscotch. If a vendor/client email has changed, you will have to add a new business contact through the Contact List page or on the Search page.
Why can't I change a vendor/client email?
To protect our community from fraud, Hopscotchers cannot edit vendor/client emails. We know this isn't ideal - we're working hard to remove this restriction. We'll update our community once this has been adjusted.
