You are saying you want to send the registration email yourself, not automatically with FusionAuth?

(There are two possible verification emails. One is for a user creation, which verifies their email whenever someone creates a user, for any application. Another is for registration verification, which again checks their email but only when someone registers for a certain application.)

If that is the case, use the skipVerification and skipRegistrationVerification settings if using the API. There are analogous settings in the admin UI as well.
